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.

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.
Steve

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.

cheers
