Title: LG Dishwasher with LE error code
Post by: y4697 on November 30, 2007, 04:32:55 PM
LG Dishwasher Model# LDS5811BB

DW will fill then stop with an error code of "LE" prior to wash cycle. Turn unit off, then back on, the drain cycle works to pump unit dry. I have tried cutting power to unit for about thirty minutes to clear, also with no change in condition.

Any suggestions on repairs?

Thank you in advance for any help.

Hello and welcome,

Display Condition LE = Motor Error

Possible Cause For Error Occurrence:

Wiring connection is OK?
The Impeller of Washing Pump is
locked.
The rotor of Washing Motor is
locked.
The Blade is locked.


Remedy:

Check the wiring connection.
Replace the cause of restriction.
Replace the Washing Motor.
Replace the PCB.

le means locked motor   disassemble the filter and work your way down to the macerator(steel chopper blade) remove it and see if the side labeled "this side up" is really up, its in english... dont think the chinese labourers paid attention to the warning cause i have seen alot that were wrong way

if it was installed correctly order the complete motor/sump assembly btw you do know LG d/w came with a 2 year warranty right? and some of the water distribution system had a longer limited warranty
read your manual, it states warranty, then price the part, then call warranty depot to ask them their service call and labour to install motor/sump

its not a fun job, you have to remove the machine from the cabinets and tip it over and back a few times to make it all work

i used to work for a company that did frigidaire and LG warranty, left there to work for a retail company, the frigidaire dealers followed me and courted my boss and now he has a friggy warranty contract (i dont mind the friggy product) but i warned him if he takes LG on i'm looking for a new job

it might be a quiet d/w but my noisey 20 year old maytag is always noisey most quiet LG are DEAD quiet half their 10 year life while they wait for parts

i'd spend the what.... almost one thousand dollars? on a maid instead of a machine that spits out motors

btw, take the front panel off your door and look for leaks, the vent tube on the blower is backwards and they all leak in time

sorry if i seem harsh but i expect more from a machine as pricey as an LG that is not servicable without removing it from the wall

I'll bet you find the motor is either locked up or "chunky" when the shaft is spun by hand. I replaced a lot of d/w wash motors. The drain pump is a separate pump/motor from the main wash motor.

Lg dishwasher started getting LE error code!
High Five to the broken wire posts!

Right on the money! Took off the door panel and sure enough a broken wire! Mine was blue. Spliced it back together and works like a charm!

Thanks! Just save me $200.00 for a simple repair.

I have the same problem, I contacted the service contract company to send a technician.  The Tech said it was low water pressure.  Does this sound possible?  Everything else I've read here and elsewhere says a problem with motor or wiring.  Was it just a lazy tech?  He barely looked at the dishwasher.

Help!

Our LG dishwasher was getting the same LE error code.  It turned out to be a simple fix, just a broken wire.  To fix it, first remove all the screws along the perimeter inside the door.  The front of door will come off, there will be some glue holding the insulation inside, just pull it off.  You'll see a bunch of wire at the bottom of the door running through a white plastic guide.  Just above that, a small grey wire and a blue thicker wire were kind of jammed into the tar-like coating of the inner door on ours.  The thin grey wire was broken, the blue one slightly cut.  The white plastic guide unclips to get access to both halfs of the wire. Just strip and solder the broken wire, wrap in some tape.  Simple fix.  I can't really see what would cause this problem.  Hope this helps.

Well, looks like I posted too soon.  After re-connecting the wires and putting it all back together, and being sure that had to be it, I'm still getting the error code.  So either I still got a bad connection or something else is wrong.  Hard to believe that it was working with these wires cut all along and something else went bad.  Guess I'll try some testing with the multi-meter tomorrow.  I'll post if I have any luck.

I had the same broken blue wire problem w/ the LDS58xx, identified after removing the front panel.

The LE code is now completely gone, and the piece of crap is back working again.

Completely sucks that I had already dismantled this to replace the washing motor (that diagnostic flowchart in the service manual is a complete joke), but, hopefully having done that gives the POS machine a few extra months of life. Also like pretty much everyone else, it was necessary to replace the drain pump after the first year.

LG appliances are to be avoided.

My LG, 6810st model, had the same LE error.  Wasn't to keen on peeling the front cover off, but after removing the 12 screws the front 'dropped' off and the wireharness was plainly visible.  After a couple minutes of staring, and not pulling on any of the wires, (1) wire was clearly 'broke'.  A red wire, with the break about dead center of the front assembly.  One end was clearly stuck into the tarlike sound deadening black substance. 

It was such a clean break that I wonder if it wasn't a combination of careless handling during manufacture, as well as the continual movement of the wiring harness at close and open.   It is no surprise that the break occured directly below where the wire was embedded into the tarlike substance. 

With a wire nut I secured the two ends of the red wire and tested the 'fix'.  The DW is running without issue.

Many thanks to the folks at this site and all who took the time to respond.    O0

I have an LE LDF6810ST - about 4 years old.
I have had the dishwasher go bad 2x with the LE code.

Both times it was an easy fix. I took the dishes out, and undid all the plastic at the bottom where the drain is and the thing that spins and washes the dishes - all the way down to the chopping blade. all you need is a screwdriver. I cleaned everything up. ends out, both times, some sort of string got hung up around the bottom of the turbine - and it collected garbage so it was pushing against the screen below it that protects the chopper. so the motor was being restricted from moving. the LE actually stopped itself from burning the motor out...
anyhow, that took about an hour. make sure you drain the water out first. hit rinse and then start and close it up. Listen for the water to stop drainaing as it always does before it washes - a minute or two. then open the washer. then work in a dry area...

note - the screw for the turbine is lefty tighty, righty loosy...opposite the norm

dont get me wrong tho, this thing is horrible. takes forever to wash the dishes and it never dried them. the water it might save by running longer it wastes in electricity to run so long. its always been loud too.

hold off. that did not work this time
now even with no "hardware" in the machine - just the post from the motor sticking up, the motot is making a terrible noise - a grinding noise. but there is no blade or anything attached to the motor - just the post sticking up, think my motor went bad. oh well.
how do i order one?

I really started inspecting the wire harness and found a larger white wire with the insulation broke also. These wires appear to have been really hot.  I think its time to pull this beast and find a different unit on craigslist  :-\ I just cant trust something like this. By the way, the motor spins freely.

 ;D I wanted to say thanks to everyone that posted the wire fix with the LE error code issue.  At first glance, I didn't see any broken wires - in fact I was looking more for a loose harness.  It was hard for me to believe that there would be a broken wire.  When I didn't see any broken wires, I moved to the bottom of the dishwasher and took the motor out.  I have solved this issue once before by taking that motor out and checking for obstructions - we found a piece of glass.  This time though, no obstructions and the motor looked fine.  So I was just about to order a damn motor for like 60 bucks then I found this website.  I read the thread and saw so many of the wire fixes, so I decided to look again.  This time, I looked behind the mass of wires that go into the harness at the bottom of the unit.  Sure as poop, there it was a black wire broken in half.  It was stuck to that black crap.  Fixed it and all is working now.  One other note, my 13 year old was really hard on the lower drawer of the dw when she pulled it out this morning, I am wondering if that didn't have something to do with the break of that wire?  First and last LG appliance I buy.  This thing is terrible.  Thanks again to all of those that took the time to post!!!

     I hate working on LG products.   Difficulty getting info,  parts,  etc,.    Have to pull out dishwasher completely to check certain parts.   Profit margin must be high for LOWES,  Home Depot,  etc to be pushing these products.    But with so many people getting them,  no choice but to learn their little quirks and repair them for most techs.  Fortunately for myself,   I have enough other work that I don't need to.    For my previous customers,  I do work on them. 
     I just wanted to mention that I had 2 similar instances.   One,  had a clean cut in the red wire upon removing the door panel.    This is what happens when you (Korea) pay the workers 1 dollar or probably less an hour to assemble your products.    Almost looked like it was done on purpose to me.      I repaired it,  dishwasher was fine.   
     2nd one was not so lucky.    A cluster of 2 wires were cut and shorted,   and this one took out the computer board.   of course,  past warranty period.   
     I've had several LG refrigerators recently that had bad main boards and only several years old.     
      LG - LOTSA GARBAGE!!!!

I have the same model. It's 4 years old. It has always been whisper quiet. We love it. A few days ago, it began returning the error code: LE.

It was a broken wire inside the door at the bottom. I spliced it back together and it's running normally again.

You all are right on the money... I have an LG 7810ST/POS  (I added the POS) Anyway this unit had an LE issue right after installation in 11/2005 and since it was under warranty, it was no big deal. Since that time it had been working good. A bit loud but it washed the dishes with no problem.
On 5/21/2010 my wife and I had returned from the beach and I wanted to wash the dishes and BAMM I get the "LE" error code. I was like, damn... So I started Googleling and I found this site.

I thought... attack the easy problem first... look for the broken wire. I thought I looked pretty good, but RATS no broken wire.

I ordered the $91 motor to install today. Then I thought since I am so lazy, see if there is an blockage going on... I removed the screen and the rotataing wand. No blockages... However the turbine screw was very loose. I torqued that down some... (left-hand screw) lefty tighty righty loosey.

The only issue I didn't see on this thread is that when you remove those parts at the bottom of the DW... be careful of the gaskets underneath... They pop off and I had to re-install them using a bit of liquid soap to make the gasket stick. So there were no issues there...

Then I said, lets look for the broken wire one more time... and BAMM there it was, a cut wire stuck to the black tar crap inside the door behind the cover.

This one was RED and cut pretty cleanly. I so soldered it back together... and ran the rinse cycle to rinse out the liquid soap used to make the gaskets stick and it seems to have run ok...

So currently the POS is back in business... THANK YOU ALL!!!

I just bought my house (built in 2007), and know this d/w was installed after the fact. I got the LE code last night and after trolling the forums here (thanks for the great tips by the way), I disassembled down to the motor. Turns out there is a "rough" spot as I turned the wheel to see if the motor was bound or not. The motor still turns, but I think the shaft is slightly bent or something else internal to the motor is resisting at that one point. I already have an appointment to have somebody come out (falls under my home warranty, I have no paperwork on the d/w itself). Turns out the warranty company is sending someone from Sears. Anyway, reassembled everything, and it appears to be working, but I can hear a noise where the motor is spinning and hitting the "rough" spot. Not a loud noise, but I am sure that is what it is. No LE code yet, but it is still not right obviously. I really like the d/w, but I would be pissed if I had paid a bunch of money for it to have all these issues that I have seen throughout the forums here. I'll keep you posted on anything else that happens with it.

The SUMP ASSEMBLY is covered under warranty for 2 years (part only/not labor).

You'll need a sales receipt (purchase date).
If not available--try contacting the previous homeowner for a faxed copy of the bill.

The *serial number* provides information about the dishwasher build date. This may be a model built before the month of May 2008.

Cut Wires Confirmed!

The DW is about 4 years old, no issues.  Suddenly last night we started receiving the LE Error Code.  I followed the instructions found online to look for corrosion or cut wires but we didn't find that looked broken.  Inspecting the PWB(PCB) showed that there was an apparently blown 330K resistor.  Since the resistor is in a circuit it can be a little odd to test, but I showed a climbing resistance that started at 90K Ohms and reached 150K Ohms within 20 seconds.

  I thought I would go ahead and check for continuity on the wires related to the motor and sure enough both the RED and BLACK wires from the motor were not only CUT, but they had been seated well inside the 'black tar'.  I suspect the only reason this DW worked for all of this time is because the wires were being firmly held together by the black tar until one of them worked it's way loose last night.

  I definitely suspect foul play by the person who assembled the DW.  It looks to me like a box cutter type blade was used to sever the wires, they even have the bent/pinched look that wires get if you crimp them to cut them like this.  There is no moving part near the wires were they were cut and there is no evidence of an object striking the rest of the wires or the 'black tar' in the area the wires were embedded into.

  I think this might be planned failure.  I have put putty in with the wires so I will know if there was any force being applied in that area from now until the next time I open it up.  I think 3 months is a good sample time if nothing else fails by then.

  This has caused to me reconsider buying anymore LG appliances, especially after seeing how many other people have had this issue and posted about it online.  If 1% of 1% of the people who experience this issue actually go through the trouble of registering/posting about it, I would be surprised.  BTW:  That is a 10,000 to 1 ratio, and just my opinion.

Either way, thank you all for your help and support.   O0

Hey guys, I'm new to this forum. I did the broken blue wire fix about 8 months ago and I got the LE error code the other day. I went back into the wires under the front cover to see the blue wire had broken again and it had not, but looking at the other wires I found another wire borken, a white one this time, and still looking further I also found two more wires about to break, a red one and a light blue one. Fixed all three wires and the error code went away.

I agree with the earlier post about a planned failure or bad handling of the wires because all the wires fixed were pushed deep into the tare stuff and none of the others were.

This forum rocks.

Thanks.

Well I'm brand new to the forum. I too am having trouble with my dishwasher. I haven't quite solved the problem yet but I am determined to get it fixed.

I need some help...... It started yesterday when i had to remove the dishwasher because we are replacing our floors. When i hooked it back up everything went well. However, that night we ran the dishes. During the last 30 minutes of the cycle the it started making a funny noise. Then it shut off and showed the LE code. Luckily, (with deep sarcasm) LG doesn't  list this code in their manual. I have so far rechecked the power source wiring, removed washing blades and rinsers down to the grinder blade, and looked through all the wiring closely by the door. I have reassembled the unit and put it on rinse cycle and it goes for 2 minutes and then prior to the motor turning on it shuts off and gives me the LE code.

Prior to me moving the unit it has been working fine for 3 years. It has always been extremely quiet but takes forever. Not to mention it washes dishes like a 7 year old would.

However, i am out of warranty and need some advice. After reading this post I am going to go back and look even more closely for the broken wires.

Let me know what you think.

Thanks,
Nick

Door wires are always the first place I check, sounds like you are on the right track, if they get embedded in th sound dampening material they will break down towards the bottom of the door.  Seems you have already checked the interior of the sump for something restricting the motor.  The biggest other reason I have seen is a main seal leaking into the motor, you might be able to see it by taking the toe kick off and use a mirror to inspect for water or rust in the base.  That would mean a new sump as the seal is molded into the housing.  If that is the problem, call LG and see what they can do for you...  Never hurts to ask.

PS - start a new thread, everyone else will see it easier. :)

this site was very helpful in diagnosing my dishwasher issue.  Unfortunately I was not one of the lucky ones who just needed to repair the broken wires to resolve the issue.  I did find 3 broken wires(its amazing the dishwasher ran at all before dying).  all three were embedded into the sound proofing and snapped at the base.  I made sure to pull free any wire that was stuck to the door as that is obviously a place the wires are supposed to have some movement when the door is opened. quick note to anyone removing the door cover, place a pillow on the floor(thicker the better) under the door to catch it once you have removed the screws.  also, there is no need to remove the 2 screws closest to the center top where the latch catches, it doesn't hold the door face on.  so after splicing the wires back together, and crossing my fingers, the problem did not go away.  I gave a close listen to the dishwasher as it cycled and after it drained and filled, I could hear the capacitor in the the main control panel attempting to start the motor with no response from the motor.  it sounds like a very high pitch sound, sorta like a disposable camera flash charge.  have your kids give it a listen, they will be more likely to hear it.  after three attempts at starting the motor, the dishwasher gave up and threw up an error.  I inspected the main circuit board so see if anything had fried from the severed wires and noticed the two large capacitor(black and gray cylindrical things) looked swollen, most likely from failure to get that motor started.  $79 later(plus shipping) I had a new motor shipped.  you can double check the motor number if you take off the kickplate on the front and use a flashlight to see the sticker.  you will most likely need to pull the wiring harness clip off temporarily from the motor to see the sticker.  Unfortunately, you do need to remove the dishwasher to get at the motor.  we had to take it outside to dump the residual water, although I suppose I could have sopped up the nasty water with a towel or something.  make sure you start the dishwasher once last time to let it drain whatever it can before starting all of this, just make sure to open the door before it refills again.  once outside, actually replacing the motor was a breeze and took maybe 20 minutes tops.  you have to disassemble the filter and get down to and move the chopper blade.  the impeller does have a left handed thread.  lean the dishwasher over, but beware, the water does not drain OUT of the dishwasher, it will drain INTO the door and soak everything(learned this the hard way....only adding to the issue, I figured I'd take the opportunity to hose the stinky broken thing out...lots of water in the door....lots)  keep the door pretty much closed when you lean it to get the residual water out if there is any.  once you have it empty, lean it on its back(unfinished side) and remove the 2 screws holding the cover plate on.  removing the motor is super simple, 3 screws holding 3 ground wires to the bracket, the wire harness that clips into it, and the 4 screws that actually hold it to the dishwasher. the motor just slips right out, and the new one just pops back in.  re-assemble and reinstall.  the whole process would have taken about an hour, but having to dry out my door insulation and circuitry with a hair dryer before turning the breaker back on added a bit of extra time. its working like a charm now and is much quieter than it has been for years(it was quiet when it was new but started getting a high pitch squeal sometimes when it ran....intermittent).  $90 and an hour verses a new $800 dishwasher and all the time that involves is well worth giving it a shot yourself in my book.  I know LG keeps getting knocked by everyone, but honestly...every appliance I have ever bought has had some sort of issue.  the forums of every brand are full of people saying the exact same thing.  learn to fix it yourself and you'll save yourself money, learn something new, and maybe even surprise yourself that its much easier than you think.

OK, add me to the list of disappointed LG owners.  My DW also came up lame after 5 years with an LE error.  Thanks to all that posted.  I know there has been a good deal of discussion about why the wires are broken.  In my case the purple and grey wires were broken; purple all the way and the grey almost all the way through.  The break was about one third the way up the door, not at the bottom as i thought it would be.  The reason for my breakage was the extra cable, which there was plenty was above the black tar substance; the black tar held the wires in place, causing the bottom sections to tight and then stretched each time the door was opened.  Finally the wire /s broke.  It was due to the black tar, if this was not holding the wires in place this failure would not have happened.  Happy the repair was simple.  Thanks again

Why do yall suppose the black tar is there to begin with? Couldn't a zip tie been just as effective in holding the wires in place?

The black tar is used in the door as insulation against sound.

I'm new to this forum. But the info is excellent.  I have the same LE code issue. Still trouble shooting it though.
After reading I was convinced it must be a wire.  And I peeled the wires out of the black tar/insulation,
but all "look" clean for a 4 year old machine. My question is really a verification that the replacement part,
if necessary, is the motor assembly.

when disassembling down to the grinder I noticed the black gaskets will not reseal.  Does anyone have a part no.

I'm new to this forum. But the info is excellent.  I have the same LE code issue. Still trouble shooting it though.
After reading I was convinced it must be a wire.  And I peeled the wires out of the black tar/insulation,
but all "look" clean for a 4 year old machine. My question is really a verification that the replacement part,
if necessary, is the motor assembly.

Wow lots of information on this site.  Thought I would update with my dishwasher.

This morning I saw the LE code.  After reading this thread, I opened the front and checked for wiring, can't find any loose/broken ones.  I put it back and decided to start it up and see what happens.  My dishwasher starts up with draining whatever's in there, then it sprays.  However, when the motor is supposed to start, it is stuck.  I then disassembled the filter assembly and cleaned it up a little.  However, when I try to manually turn the motor, I can't get it past a point with my fingers.  If I use a pair of pliers, it goes through but then would just get stuck on the next revolution.  I placed an order for a new motor from the link in this thread, as well as a gasket since one of them doesn't reseal.  Should get them on Wednesday and I will report back on what happens.

Okay guys.  Got the motor and gasket this morning.  Disconnected the water line and the drain line, took out the dish washer, disassembled the filter assembly, tilted it forward, some water came out, took off the bottom plate held by two screws, disconnected three ground wires, took off the four screws that held the motor, took off the motor and disconnected the harness, put the new motor in, put the filter assembly back in, put the dishwasher back in, connected the water and drain lines, and it starts right up.

It really is very simple.  Good luck to anyone in the future with the LE code!

Hi guys. I've had my LG Dishwasher since 2007 and I have to say that I love it and its been pretty problem free until now. I was getting the 'LE' code so I did a google search and found my way here. I read this entire thread to find out what was wrong and it was the BLACK wire behind the front door. It somehow got cut. I tried connecting it without turning off the power to the dishwasher and got shocked so remember to turn the power off if you're going to try this at home. I turned off the power, spliced the wires a bit more, soldered the connection back together, taped it up with electrical tape, and then it was back to normal. I did notice that the insulation on the inside of the door had a small burn mark and it looks like it was in the same spot as where the BLACK wire got cut. Since it shocked me, it only makes sense that this is a LG design error. They should do a recall if its happened to most of us. Thanks again to everyone who posted in this thread. Saved me money and time.  O0

I have the LE problem with a different twist.  I pulled off the front door to check for the wiring problem many have had and couldn't find a break.  However, there was evidence that water had been entering the door along the left side.  Poking around, I found that the bottom gasket was twisted on the right side, allowing water in.  It appeared that the water had reached coil at top left.  However, the coil tests for continuity.  Of course, I want to investigate all possibilities before replacing the motor.  Has anyone replaced that gasket?  Just how to reach it isn't immediately obvious.  One irony is that there's a sizable LG plant here in Huntsville, AL, and my wife is friends with the wife of the plant manager, not that it will help.  They really just manufacture electronics here.  I once tried to buy an Onan generator from the plant here and was told that it would have to be shipped 100 miles south to Birmingham and I could pick it up there...   ???

Learned a bit more since my initial post.  There does appear to be moisture in the door, but it may be from the air vent connected to the vent fan.  After disassembling the filter  down to the pulley attached to the rotor shaft, it appears to be immovable.  Since the wires appear intact, it may be the motor itself...

Well, the motor came in from RCI*, and it was so wimpy I thought I must have ordered the wrong part.  Checked the old spindle in the machine and it's the same size and the shape, etc., look the same as in the blowup diagram I have.  I started remembering back.  I bought the house where I live in.  Fairly soon after moving in, the KitchenAid dishwasher failed.  It had been installed in 1961.  It was a backbreaking task to get that sucker out to the curb (200' away).  I replaced it with a Kenmore which only weighed about 2/3 as much and was easy to manhandle.  I was afraid that the lighter weight meant that the Kenmore wouldn't last as long.  It lasted 23 years.  Three years ago, when I bought the LG and installed it, it was even lighter than the Kenmore.  It, of course, lasted only 3 years before failure.  It was signaling that it was in trouble, taking multiple tries for the motor to start.  I'm already researching other brands, which I should have done before buying the LG...

Well, new motor in and dishwasher humming along.  The only problem was I punched a hole in the mesh in the sump cover with my screwdriver.  I'm going to order a replacement, but we really wanted to test the dishwasher.  After discussing various cements, my wife suggested soldering the hole and it worked, at least through one cycle and it still seemed solidly stuck.  I had various types of solder around and I looked for one that was lead-free.  I found a spool from Alpha Metals, made in USA, which I used.  Later, I happened to look at the back and there was a hysterical warning "This product contains LEAD!"   ???

Thank you guys!  After hanging around from 12 to 4 and getting stood up by the repair company I ended up here. Sure enough the blue wire, stuck in the tar, was broken clean.  Repaired the break and shes working again!

I had a burn spot on the insulation too, this seems like a factory defect that could lead to fires.  I wonder if there is any silent recall on it.

Out of the dishwasher and into the fryer.

Guys,  I really need your help! I have had my LG dishwasher for about five years and aside from the LE error code, have really liked it.  It does take a long time to run a cycle,  butwhen running, you can't even tell that it is on, it is so quiet.  My problems with my dishwasher started about one year ago when i got my first LE error code. A repairman told me about the cut wire situation, and sure enough, I had a blue wire cut. After repairing, the dishwasher was as good a new.

Then about one week ago,  I started getting a new LE error code.  Knowing what to do, I took apart the door and carefully checked every wire. Seeing that no wire was cut, I assumed that it was my earlier splice job.  I took that apart and respiced and retaped that blue wire,  put the door back on and prayed that that was the last of that problem.  Unfortunately, the LE error code came back.   Having read through this thread carefully, I assumed that it may, in fact be a motor problem. So i dismantled the grey piece in the middle of the unit (I will call this the top motor housing)  which had eight screws holing it down.  Upon checking the motor,  i happily found a large piece of glass.  In trying to put he top motor housing cover back together,  there was a thin rubber gasket that fell off.  It was extremely difficult to get this gasket back on.,  and i leaned on the open door to better position myself. Ultimately, I broke the thin gasket. In trying to screw the motor housing cover back on,  I accidentally punched through one of he mesh filters with a screwdriver. Drats!  Worse yet was when trying to close the door,  I realized that my weight bent the hinges or something and the door doesn't close properly (I'll search for hat fix in the forums after sending this email. Worse yet, when running the unit (by forcibly keeping the door shut),  I still get that damn LE error code.

Any help would be appreciated.  When describing the parts of he motor,  or parts of the dishwasher, please be descriptive.  Although it wouldn't be apparent from this posting, I am actually quite handy.

Thanksin advance for all of your help.

You never mentioned if the impeller was free spinning when you took out the broken glass.  You should check the impeller to see if you can turn it freely.  If it feels sticking or hard to turn, replace the entire sump assembly.  If you're going to replace the sump assembly, you might as well change the wire harness as well to get rid of the broken wire issue.

As for the door, you may have bent the door frame.  The inner liner is covered by LG's lifetime warranty.  You can order it from LG and just tell them it's rusting.  They will send you a new inner liner.

Hope this helps.

Post by: ApplianceGuru on March 30, 2012, 10:58:58 PM
If you fix the broken wire, make sure you also fix the root of the problem.  It looks like LG started adding a thick sheet of clear plastic at first, and now the newer models ship with tar that has some type of fabric attached to it  This prevents the wires from sinking into the tar, and absorbing so much heat that they end up melting/breaking apart.  (I assume. I don't have any official comments from LG)

Some techs have been known to throw a large piece of thick plastic between the wires and the tar.  I bet fiberglass insulation would do the trick also, as long it doesn't have any ignitable paper on it.

We just bought our LG dishwasher (fridge and gas range) 1 1/2 years ago and we've had problems with all. Unfortunately we only got extended warranty on range and fridge and now we are having issues with the dishwasher-again. The dishwasher (model #LDF7920ST) is now displaying the LE error. Would it be the motor already??? I ready an earlier post that said that we have a 2 year warranty but I phone LG already and they said that we only had a 1 year warranty (we're Canadian, if that makes a difference). If we were to DIY, where do we go first... pull dishwasher out of cabinet, open up back?? look at loose wires?

I also removed the front panel and found a broken grey wire (completely severed) I also found another grey wire with a dimple in it, when I pulled on it the plastic coating was the only thing holding it together. I spliced both and the dishwasher works fine. The wire that was only held by the coating was a live wire, be sure to turn off power.

Hey guys first post

Have the dreaded LE error.  read through all the posts. not cut wires so assuming its the sump motor.  all threads ive read say to replace the "sump assembly" but the motor can be purchased separately (part of the assembly).  is it that difficult to simply replace the sump motor by itself? anyone have any instruction?

thanks for your help

Update: pulled apart the sump assemble down to the slicer/cutter.....no obstruction.  Turned the motor by hand and had one rough spot not seized but a noticable drag at that point the roatation.  took off the pully and then tightened it back down, put everthing back together and started it up.  Ran a full cycle with no LE code but can definitely hear the motor whining.  Good think I ordered the sump motor.  Looks like i will just replace it anyway before I put everything back in place.  Will update again after install.

I have a 4 year old LG LDF6810 and I've read through all of these postings but didn't find any that stated how long the dishwasher ran before getting the LE code.  I've gone 30 to 40 minutes before it stops and displays the LE code.  Should it run so long before stopping?  I run a 14 minute rinse cycle without problem.

I took off the door panel and didn't see any obvious breaks/opens in the wiring but I should take another thorough look because of the large percentage of posts seem to find that to be the ultimate problem.  But I'm hoping someone will tell me that it's not the motor if it runs 30 to 40 minutes before failing.  Could the long duration into the cycle mean it's a build up of heat causing the problem?

OK I have the same problem with the LE code on my LDS5811ST Dishwasher.  I took the pump apart from the inside and found a hard plastic baby bottle straw that could have been preventing the blade from turning.  I cleaned it out and it turns freely now by hand.  I took it apart from the bottom and saw that there was some of the soap tablet stuck in the drainage pump.  I also took the door apart, noticed two wires that had a clean cut in the plastic but did not cut the wire.  I taped that up. 
I put it all together again and after about a 90% cycle, there is the damn code again.  Could it still be the pump even though it runs during most of the cycle?  It will drain in the rinse cycle as well.  Or, is it a problem with a computer...... 

Please help..... :(

Hey guys,
I got the LE error code recently & have a few questions.  (LDF6810ST)
This is the 2nd time, the first was a few years ago & I found this thread most helpful.
I fixed the wires that time & it worked.

However, this time wires were fine, so I assumed it was the motor (the one that has the blade &  plastic impeller on it).  I've swapped that out, but I'm still getting the LE error.
I've double checked the wiring (spent an hour today checking each one),  so I'm 99% wiring is fine.

However, the largest gasket (with all the bends) was torn up/broken in a few spots.

I'm going to order one this week, but I was wondering if anyone knows if a bad gasket could be the sole cause for the error?

I've seen a few threads where people have said it's the sump motor or Recirculation pump... Like above.
Title: Re: LG Dishwasher with LE error code
Post by: john63 on January 31, 2013, 12:57:02 AM
<<<However, this time wires were fine>>>

**********

Verify that all previously repaired/taped wires are fine (especially the thin low voltage wires).

Inspect the wires at the bottom of the door too---inside the plastic sheathing.

Re-tape the entire harness from the bottom of the door up to the detergent dispenser housing.

Add a small section of cardboard between the wire loom and the tar-like insulation on the door.

************

<<<so I assumed it was the motor (the one that has the blade &  plastic impeller on it).  I've swapped that out, but I'm still getting the LE error.>>>

************

It's common for DIYers to *forget* to plug the new WASH MOTOR.
Verify that it's plugged in---from the bottom of the dishwasher---with the lower kickplate removed.

Purchasing a WASH MOTOR only---is a huge risk.
Check the Build Date on the bottom of the WASH MOTOR---if the date is June 2008 or newer---should be good.
If an older build date---a flawed motor.

I recommend replacing the entire SUMP ASSY (AJH31248604 (http://www.repairclinic.com/PartDetail/Pump-and-Motor-Assembly/AJH31248604/1472730)) to avoid accidently receiving older/obsolete/factory-defective-as-new/no longer used inventory.

<<<However, the largest gasket (with all the bends) was torn up/broken in a few spots.

No.

An improperly installed or damaged Sump Assy gasket will cause poor wash performance.

Thanks.

I checked all connections, re-checked all wires, and re-spliced all previous wires.

We paid $800 for this think 5-6 years ago.  Both upper & lower trays have rusted spots/broken  tongs.
I've spent $200 parts over the last 2 years on this thing.
No way am I going to spend another $150 for a bottom end.
I really liked it when we got it, but its what what I consider a piece of junk.

I'm going to hit some sales & get an non LG washer this week.

Anyone need any parts from this thing?  (I may need the plug wire & hoses for the new unit).

I'll make a deal on the motor I just bought.

Hello,

  I had this same issue which just occurred within the last week. The LG dishwasher is 4 - 5 yrs old and was working fine until recently it started making a whining noise and would quit with a LE error code. I was able to get it working fine now although I am not sure if what I discovered will solve everyone's issue.

  Step 1: Use the rinse cycle to drain the unit of any water. Listen to the machine for when it stops draining and turn it off before it actually starts the rinse cycle.  Either unplug the unit or turn the breaker for it off/remove fuse at panel at this point. Hit the power button to ensure there is no power to the unit.

  Step 2: I first checked the wire harnesses and all wires within the door including removing the top button/cluster (2 top-center screws to remove it). Some of the wires in about 3 places within the door were touching the black sound barrier material & void of insulation. With close inspection I did not see any breaks in wires although to avoid future issues I used some pink insulation to patch up where the manufacturer neglected to put insulation (anywhere where wires were or could touch the black sound barrier material). I screwed the door back on and continued my inspection..

  Step 3: The next step for me was removing the screws in the bottom-center of the unit (within the dishwasher) around the impeller. This is where I found an issue with this model concerning the black gasket located underneath the removed plastic housing. The gasket seemed too large for the groove as I could not get it all to fit into place without some slack popping out no matter how hard I tried. In fact when I lifted the plastic housing, part of this gasket was not in the groove before I touched it imo because it is too large!! Dishwasher soap scum had made it past the faulty gasket and caked around the area where the motor spins the impeller. Use some paper towel with a bit of rinse aid on it which will clean the soap scum nicely. Give the motor a manual spin with your fingers a few times and make sure no goopy soap scum is around where it spins (clean it nice). For the one piece black gasket, cut it on the left side then make sure it fits in the groove nicely all the way around and cut the very small bit of slack but ensure the 2 ends more or less meet. Use some gasket sealant (ie. high temp might be best but as long as it can handle the machines hottest temperature) on the end of your finger to seal where the break in the gasket is. Screw back on the plastic housing and let the gasket sealant dry a bit. 

Step 4: Run the dishwasher through its regular wash cycle. For me it still made the noise for the first 10 minutes or so and then it went away.  After this I have not had an issue since & hopefully the issue has been resolved. If I am wrong, I will report back to say so but imo the issue was the over sized gasket that popped out during assembly that let moisture and soap scum around where the motor spins the impeller.  I am by no means an appliance tech although I am somewhat automotive and electrical savvy. The supplied gasket is too long for where it is being used!

<<<The gasket seemed too large for the groove as I could not get it all to fit into place without some slack popping out no matter how hard I tried.>>>

*************

This type of GASKET---and the difficulty of handling/installing/keeping-in-place---is an indication that it's the *original* style gasket.

Used from 2004 thru 2008.

In your case---the SUMP ASSY has a *flawed* WASH MOTOR.

Because of this type gasket---it is NOT recommended that only the WASH MOTOR be replaced.
Newer LG dishwasher SUMP ASSYs have a different gasket design---which is far easier to handle and allows for (if needed) the possibility of replacing a WASH MOTOR rather than the entire SUMP ASSY.

In most cases---the original gasket will become too stretched---when the FILTER HOUSING has been removed (pulling).

Replace the SUMP ASSY (AJH31248604 (http://click.linksynergy.com/fs-bin/click?id=omv7WULuxaw&subid=0&offerid=225193.1&type=10&tmpid=2111&RD_PARM1=http&RD_PARM2=%253A%252F%252Fwww.appliancepartspros&RD_PARM3=.com%252Flg-motor-pump-assembly-ajh31248604-ap4447671.html))

Inspecting the WIRE HARNESS from the bottom of the door---up to the area of the Detergent Dispenser---is a good thing to do on 2006 and older LG dishwashers (possibly very early production-run models for 2007 as well).

Repair any wire(s) that have been pulled apart.
Wrap the Wire Harness with electrical tape---from the hinge of the door up to the dispenser.
Place a small section of cardboard between the Wire Harness and the black tar-like insulation.
Re-install door panel.

*******************

<<<imo the issue was the over sized gasket that popped out during assembly that let moisture and soap scum around where the motor spins the impeller.>>>

*******************

Incorrect.

The cause of the "LE" error in LG dishwashers built prior to 2008---was a manufacturing issue.

All Wash Motors were highly prone to premature failure ("LE" error).

A good attempt at failure analysis though---considering that you are not an appliance servicer :)

john63,

  Thanks for the response. I understand what you are saying regarding the gasket being stretched when the plastic housing was removed but this does not explain why there was stuff (water/dishwasher soap) getting past the gasket prior to taking it apart which was clearly evident. If I understand you correctly regarding a new SUMP that comes with a new type of gasket, I would not buy a SUMP solely for that purpose as that would seem to be a waste of money. Imo fixing the gasket in the fashion that I did seemed a better choice and furthermore could one not just order a new gasket instead of the whole SUMP assembly? Also I believe using insulation as opposed to electrical type was a better solution.

Regards.

 :oops: I meant electrical tape in the last sentence of the previous post and can't seem to edit.

Mine made it through wash, but would not drain.
I took the advice for the easy fix, and took a look at the wiring behind the door.
I found about 1/3 of the way up from the bottom of the door, where all the wires run, A blue, white and larger gauge orange.
The white and the orange were either burned or worn through.  There (fortunately) was enough slack to strip and solder.  Rather than heat shrink, I used elex black tape, and wrapped enough to provide some cushion and separation.  Works great now.  Thanks to you folks for posting to check the easy first.    A dozen screws and a close look at the wires is WAY easier than plumbing, seals, sealers, etc. etc. that you find in abundance in a beast like this, Re-joining a couple wires is easy.  Good soldering iron and some patience checking wire,  AND I won't be worrying about dish pan hands, either!

Great thread. My LG dishwasher is the LDF6810ST, I have this same problem. I inspected the entire wire harness in the door panel, up to the control board and saw no broken wires and taped up spots where it was pressing into the sound dampening material. Error persisted. Then I replaced the entire sump assembly. Error persists.

Argh. From what I've seen elsewhere the next step is to replace the PCB control board. Has anyone had this be the solution?
