Title: LG washer erratic draining problem and resolution
Post by: wildimaginations on May 04, 2012, 09:26:28 PM
I had a customer with an erratic draining problem on her LG washer.  Most of the time, everything would work fine but about every 4th to 8th wash load, the OE error code would come up and would not drain.  I've come to her aid every time for the last 3 months trying to figure this thing out and every time I was there, it would work fine.  Today, I was able to get it to not drain and found the problem.  The drain pump was working fine but when it wouldn't drain, I could hear the drain pump cavitating like there was air inside the pump.  It would take about a minute of pumping till all of a sudden you could hear the water slowly get sucked into the drain pump and start draining out of the washer. 


In the picture below, I pulled the drain line siphon hose and found that it was clogged up.  I used some compressed air to blow it out and now the washer is draining perfectly.  What's happening is the siphon hose was plugged up and not allowing an air break at the drain line U turn when the pump stops causing the drain water to pull water out of the tub to the point of pulling air into the drain pump and trapping it inside the pump.  When the next time it tries to pump water out, the air is stuck inside the drain pump cavitating until some water from the tub gets into the pump area.  By clearing out the siphon break hose, the air break causes the water to go back down towards the drain pump and removes the trapped air inside the pump.  Now the pump is fully primed and ready to pump water out when it's called for.

<<<I had a customer with an erratic draining problem on her LG washer.  Most of the time, everything would work fine but about every 4th to 8th wash load, the OE error code would come up and would not drain.>>>

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

In 9 out of 10 cases---this is due to a weak/failing (intermittently slow) DRAIN MOTOR.

Since the MODEL & SERIAL number are not provided---it's hard to know for sure. Most often this occurs in LG washers at or about 5 years old and used often (a family of 4 for example).


The function of the black anti-siphon hose (pictured) is to prevent *continuous draining* of water---especially right after a drain cycle has completed---and rinse-water begins entering the tub.

Particularly in circumstances---where an installer has jammed the drain hose far into a drain standpipe (into the "trap") or secured the hose to a utilitub---with the outlet at the bottom of the utilitub.

Early LG washers were prone to complaints of : "Fills & Tumbles/Loses Water--- Fills Again & Tumbles/Loses Water---repeatedly.

The black anti-siphon hose was added to remedy this symptom.

<<<What's happening is the siphon hose was plugged up and not allowing an air break at the drain line U turn when the pump stops causing the drain water to pull water out of the tub to the point of pulling air into the drain pump and trapping it inside the pump.  When the next time it tries to pump water out, the air is stuck inside the drain pump cavitating until some water from the tub gets into the pump area.  By clearing out the siphon break hose, the air break causes the water to go back down towards the drain pump and removes the trapped air inside the pump.  Now the pump is fully primed and ready to pump water out when it's called for.>>>

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

Correction---the Pump Housing is *always* "primed" whenever water is in the tub.
At the end of a drain/spin cycle---at least 2 to 4 cups of water will remain in the Pump Housing.

The model number is WM3677HW (http://www.repairclinic.com/LG-Washer-Dryer-Combo-Model-WM3677HW-ID-684500-Parts).  Serial #508KWBY00165.




I always thought that way too but this job proved me wrong.  There was air trapped inside the drain pump and there was no way to get it out with the siphon hose plugged up.  The next time you come across an LG washer with the siphon hose, pull it out and plug the line and see what happens.  It's really interesting.

I believe a pump can cavitate with a tub full of water.  I've seen it a lot with dishwashers, especially Frigidaires.  Thanks for the heads up. You may have saved me from some frustrating callbacks in the future.

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

Anecdotal observation.

And incorrect.

The *original* LG washers did NOT have an anti-siphon tube at all and draining wash water was never an issue.

Improperly installed drain hoses---*was* a concern---hence the black tube/anti-siphon.

This washer was manufactured August 2005---more than 6 years old.

The DRAIN MOTOR is the likely culprit :)

Not trying to convince *you* to believe otherwise---however---others reading this thread should be informed.

The drain pump was replaced 3 weeks earlier.  Drain pump was not the problem. Customer still called me back with the same issues.

<<<The drain pump was replaced 3 weeks earlier>>>

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

What other critical details have you left out or forgotten ? :)

Was the drain hose attached to a standpipe---and wrapped with tape to prevent water from gushing out?

A partially-restricted drain can give the symptoms you've described initially.

The main point here is that---we don't want other servicers and DIYers---to say:

"Hey my LG washer drains erratic too---let's check that little black hose-thingy at the top of tub."

The function of the anti-drainback hose is to prevent siphoning of water during wash---if the drain hose has been improperly installed (not inhibit draining---even if it becomes plugged).

I have never encountered a problem with a blocked anti-siphon tube *preventing drain*.

The original LG washers (which did not have a siphon tube) drained just as fast and reliably.

In 14 LG training seminars---not once has this been discussed as a possible "Slow or No Drain" issue.

An incorrectly installed drain hose---is a possibility to consider when servicing an LG washer with the complaint that you've described.

Title: Re: LG washer erratic draining problem and resolution
Post by: john63 on May 06, 2012, 11:10:36 AM
Alrighty---I have just completed two loads of wash in my LG washer (both were Speed Wash cycles).

For this "laboratory test" (in our laundry room)---the "offending" black hose was disconnected from the nipple fitting at the top of the tub---and plugged/blocked.

The findings were stunning---the wash water drained precisely the same as it had when the little black anti-siphon tube was still attached to the tub. Confounding.

During my test procedure---it dawned on me that---perhaps when "Wild" had used compressed air to blast the little black hose *clear*---he had dislodged a partial drain restriction in the section of DRAIN HOSE that "runs" from the Pump Housing-to-the-plastic-gooseneck.

And then---incorrectly concluded that indeed---a blockage at the black anti-siphon tube was the source of the *erratic drain* complaint.

These findings can also be performed by anyone & everyone with an LG washer---for verification/confirmation.

I don't know why you're going to all this trouble to discredit Wild.  He has been the LG expert on this site and I appreciate his informative posts.  Since the drain problem is so intermittent, two wash cycles may not re-create the problem.  Try leaving vent hose plugged for a few weeks and see what happens.  As for me, if I find an intermittent draining LG washer, I will check for all possible causes including a plugged vent hose.

<<<I don't know why you're going to all this trouble to discredit Wild.>>>

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

So---if someone posted that a Whirlpool washer is not agitating or spinning but *does* fill and drain the water...

And has found that the DRIVE MOTOR is the cause...

To you---that is not only "accurate or possible" but also inappropriate to challenge?


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

<<<Try leaving vent hose plugged for a few weeks and see what happens.>>>

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

A moot exercise---if you've read any of the above posts carefully---you'll notice that the *original* LG washers did NOT have an anti-siphon tube.

There are still LG washers being used in this configuration---without issue.

John63... try leaving the anti siphon hose plugged for 6 months.  That's when the customer starting noticing the problem but let it go for 3 months before it got to me and I was on it for 3 months as well.  Also, this was an erratic problem so it didn't happen all the time. She says it happens about every 8th to 10th wash load.  This customer uses this washer 7 days a week, 2 times a day.  You only did it 2 times, but I kept testing this machine till it gave me an OE error code.  Fill and drain, fill and drain, fill and drain. 

Yes I did use compressed air to blow out the anti siphon hose, but before I did, the drain line would clear out properly whenever it was working.  After blowing the line clear, there was no difference in the flow of water drained out and there was no debris.  I checked by putting the end of drain hose into a 5 gallon bucket to see if any debris came out.  Little pieces of lint debris came out but that's it.

Another thing I forgot to mention is that this is a washer / dryer combo.  So the lint buildup problem may have something to do with it.  Don't know though.

I could see a siphoning drain hose siphoning all the water out of a drain pump, and leaving an air pocket inside the drain pump. 

You would think the drain hose would allow air to be pushed out of the pump when the tub filled with water again.

I will definitely keep this tip in mind if I run into intermittent drain problems on an LG combo.
Title: Re: LG washer erratic draining problem and resolution
Post by: john63 on May 08, 2012, 05:01:33 PM
If the DRAIN HOSE is installed correctly...

Not installed completely into a standpipe---down to the drain trap...

No tape has been installed on the drain hose at the top of the drain standpipe...

Not installed in a utilitub near the bottom ---slow draining of the *utilitub* will cause siphoning of water from the washer---if the LG washer is an older model without the anti-siphon hose OR in a newer model with a plugged siphon tube...

There will be no issues or complaints with "slow" or no drain".

 <<<As for me, if I find an intermittent draining LG washer, I will check for all possible causes including a plugged vent hose.>>>

That's perfectly fine.

Others would be wise to avoid wasting their diagnostics effort/time trying to identify slow/no drain complaints---by incorrectly assuming that the small/black anti-siphon hose at the top of the tub assy---is the culprit.

I have an LG WM3360HVCA Front Loader, which was giving me an OE error. Of course I didn't get the extended warranty, am at 1 1/2 years..  Checked the inline filter, pretty clean, nothing that would stop water. I did the smart diagnostic check, the person on the end of the line figured it was the pump. OK. so this is a spendy washing machine, so I scheduled a repair visit. That was over a week out. No complaints, but what the heck. Did some online research.  Went back and tried the washer again, using the spin cycle like the diagnostician told me. Did not get any water out, water was visible in the tub. Took the drain hose, blew it back, heard water moving and was able to clear the line. Tried the spin cycle, water pumped out. Wheee! Only worked once. Could hear the pump humming, no other souncs. Found a youtube video on replacing the pump, thought what the heck, it isn't under warranty anyway, carefully disassembled it. Pretty simple process, I like the engineering and the video really helped a lot!  Pump looked pretty good, no debris. Pulled the pump out of the housing, pulled out the rotor assembly with the internal magnet, water drained from there. O ring sealed, don't think it should have any moisture there.  Reassembled, found some insulated female spade terminals and plugged her in.. no hesitation, slight ticking noise. Everything appears tight, no debris in the housing or impeller or visible behind the rotor shaft.  Put everything back in place. Ran a cycle, no problems. Yey!

But, it only worked a couple of times, then got the OE error again. Mind you, at this time, I had the hose Tywrapped to the utility sink faucet so I can observe water flow. Good to know about the hose being stuffed down the stand pipe too far, thank you for that.

So, ordered new pump online, 2 day freight, just replaced it, only took an hour this time. Secured the drain hose appropriately, started her back up, did a full cycle w/o clothes, seems to be running fine. Time will tell. Did I miss anything?

We have a lg wm2277hw and started getting OE code last night. I pulled drain hose and nothing came out. I unscrewed the filter and drained some water out and reset and it completed the load. This morning.....same issue. I pulled the drain hose, plug and attached my small compressor to the end and slowly applied air......plugged! I applied more air and POP! out rushed water a what looked like mud! I drained completely pulled screen and it was loaded with beach sand! Cleaned completely and it's running like a champ!

Ok, it worked for the day then thru a PF code last night......then OE again this morning. Naught new pump, installed and it started, stopped after 2 mins. I rested on speed wash, it ran then shut down. OE. Code again. It urns thru sometimes and sometimes it stops with code......need a possible reset?

Post by: john63 on July 14, 2013, 12:51:48 AM
<<<We have a lg wm2277hw and started getting OE code last night.>>>

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

LG WM2277 washers are now more than 5 years old---about the time a DRAIN MOTOR will fail.

Use the correct Drain Motor (4681EA2001T (http://click.linksynergy.com/fs-bin/click?id=omv7WULuxaw&subid=0&offerid=225193.1&type=10&tmpid=2111&RD_PARM0=http%253A%252F%252Fwww.appliancepartspros.com%252Flg-drain-pump-motor-4681ea2001t-ap5328388.html&RD_PARM1=http&RD_PARM2=%253A%252F%252Fwww.appliancepartspros&RD_PARM3=.com%252Flg-drain-pump-motor-4681ea2001t-ap5328388.html)) and verify that it's a new motor from an appliance parts retailer.

The Drain Motor is located on the left side of the Pump Housing---if looking at the washer from the front.
The Recirculation Motor (an entirely different motor than the drain motor) is located on the right side of the pump housing. These two different motors are *not* interchangeable.

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

<<<<I pulled drain hose and nothing came out.>>>

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

The small black drain tube at the pump housing strainer?
This small tube is used---to allow a means of draining water from the tub---if the Pump Housing has a blockage or a failed Drain Motor.
It is not uncommon to find the little tube plugged by debris (scum/grit/sand/etc).
A blocked/restricted drain tube at the pump strainer---does not affect washer performance.

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

<<<Naught new pump, installed and it started, stopped after 2 mins. I rested on speed wash, it ran then shut down. OE. Code again.>>>

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

If the Drain Motor is verified to be the correct type...

Unplug the washer and remove and inspect the *bellows hose*---which is located at the bottom of the tub assy. This black/soft hose---runs/routes from the bottom of the tub---to the Pump Housing. Check for debris/blockage.

Verify that the Drain Hose (gray color) is correctly installed.
If the Drain Hose goes to a *STANDPIPE*---check that it is inserted only 6 to 8 inches and secured to the standpipe with a zip tie or tape.
The top of the standpipe should *never* be taped or have a rubber cap on it. This is sold at some hardware-type stores---as a seal/cap to prevent water from backing up from the standpipe.
The top of the standpipe should be "open-to-atmosphere"---to allow proper draining of water.

If the Drain Hose goes into a utility-type tub---check that the hose is shaped/formed into a "gooseneck" and secured to the side of the tub (again 6 to 8 inches into the tub---not all the way into the tub).

If the Drain Hose is fine---unplug the washer and then remove the top cover of the washer.
If facing the washer from the front---locate the MAIN BOARD at the rear/left corner of the washer (at the top).
In this location---you'll notice a small diameter black hose attached to the WATER LEVEL SENSOR.
Pull this hose off of the Water Level Sensor---and either blow into it or use compressed air to clear any possible obstruction within the hose---or within the AIR BELL at the bottom of the tub.
Never blow air into the WATER LEVEL SENSOR itself (only into the black tube---back into the tub assy).

Compressed air can also be used to check/clear the DRAIN HOSE (gray color).
This is best done by disconnecting the Drain Hose at the Pump Housing---and pressurizing/blasting air in the same direction as drain-water flow in the drain hose.
If there's any blockage/restriction in the Drain Hose (Gray)---it'll usually occur at the drain gooseneck located at the rear corner of the washer (on the left side).
Sometimes a bright flashlight can be used to shine light through the white-colored drain gooseneck.
If a blockage is there---it'll appear as a dark shadow.

After re-assembling everything (and double-checking)...

Test washer function.

John, I have a couple of questions.  I've got a washer with a noisy circulation pump and it's not pumping, the hose is clear.  I disconnected the power from the pump until I can return with the part. The parts diagram only shows the drain pump, so that's what I ordered.  Since reading your post, I checked again and found the circ pump, 4681EA2002H (http://click.linksynergy.com/fs-bin/click?id=omv7WULuxaw&subid=0&offerid=225193.1&type=10&tmpid=2111&RD_PARM0=http%253A%252F%252Fwww.appliancepartspros.com%252Flg-motor-pump-assembly-4681ea2002h-ap4438603.html&RD_PARM1=http&RD_PARM2=%253A%252F%252Fwww.appliancepartspros&RD_PARM3=.com%252Flg-motor-pump-assembly-4681ea2002h-ap4438603.html). What happens if replace the circ pump with a drain pump? How important is the circ pump, it seems to run fine without it?
I'm having trouble rescheduling the call, probably because it's working and quiet now.  At least now when I do go back I'll have the correct part.

<<<I've got a washer with a noisy circulation pump and it's not pumping, the hose is clear.>>>

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

In most cases---if the circulation pump is either noisy or does not run---there's something (debris) in the pump housing. Usually a small button.

This type of symptom can throw off a tech at times---since the recirculation pump is only energized a few times during the cycle.

Customers will explain/describe that the washer is very noisy at a specific point(s) in the cycle---but then continues to functioning perfectly thereafter.

If a blockage occurs---it'll usually be at the nozzle on the door gasket (clump of lint).
This can be removed---in most cases---by grasping the ball of lint at the nozzle and pulling it out. It helps to then put the machine in Test Mode---add a little water into the tub---activate the Recirculation Pump Motor.
If there's additional lint within the hose/nozzle---you'll be able to remove that as well.

I've never had a failed Recirculation Motor---but that's not to say they're bullet-proof. The total run time of a recirculation motor is so low---that wear and tear is minimal.

The Recirculation Motor used on the LG washer is the same as the Drain Motor used on 1st generation LG dishwashers (not the current D/Ws).

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

<<<What happens if replace the circ pump with a drain pump?>>>

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

The Drain Motor has a much higher flow rate than the Recirculation Motor.

If installed---as a replacement for a failed Recirc Motor---the washer will continue to function normally.
When the Main Board energizes the recirculation feature---the water will come through the nozzle on the door gasket---too strong/harshly (but cause no malfunction).

It's when a Drain Motor is replaced with a Recirculation Motor---that there will be a slow-drain complaint/symptom.

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

<<<How important is the circ pump, it seems to run fine without it? >>>

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

The washer will perform perfectly fine---without the Recirculation Pump Motor (unplugged).

As I'm sure that you know---many LG washer models (except high-end units) do not have a Recirculation Motor at all.

Good Luck :)

I contacted LG and they said the drain pump and the recirculation pump are the same thing.  I took it apart and the two motors clearly look different.  I'm trying to confirm if 4681EA2002H (http://www.repairclinic.com/PartDetail/Drain-Pump/4681EA2002H/1461702) also fits for my LG wm2277hw washing machine. Can anyone confirm? Many thanks!  :)

With all this talk about pump problems I have a question: Since you all are out working on all brands and type machines and seeing how different people use different brands of detergent, have you ever noticed there was a certain brand that was better on machine parts and one that seemed to be worse on them?


I can remember a guy working on a Kenmore machine for my Mom back in the 70's. The pump wasn't letting the water out which lead into the detergent talk. He asked her what detergent she used and she said Tide. He said that he had noticed over time that Tide seemed to be more harsh on pumps. He said his wife used Cheer because he had seen in other machines using Cheer that they seemed less  corroded and it seemed less harsh on parts.
Several years back my neighbor had a problem with her Kenmore which she used Tide w/bleach all the time. When the guy got it apart she said she was shocked how Tide had built up under the inside tub. She said the guy told her Oh, they all look like that. He then told her if she would use Wisk all the time she wouldn't have build up. I guess because it was liquid?? or because there was an ingredient in it that helps keep the tub clean.?


So, just wondered if any of you ever run into messes of built up soap, or any machines you could tell the parts looked worse than others due to using certain products.


Thanks!

This is an old thread but I hope someone can answer my question. My drain tube started leaking on my LG washer so after seeing a video I decided to replace it my self. My machine is only a couple of years old so I was surprised the tube had developed holes in it already. Oh well. The problem I encountered is that when I took it apart, the small air tube that hooks onto the top of the tube is not connected to the drain tube as you can see in the picture. But my new hose came with the hose so should I hook it up or leave it capped off on the tub like it is right now?  Thanks for any replies.

The original poster's issue of his customer's OE pump issue seems exactly like what I am experiencing with my LG WM2016CW.  When it runs without the error, the flow out the drain hose is solid and fast.  Every 4, maybe every 6th, maybe every 8th load (no real rhyme or reason) the machine will cease operation and display the OE error code.  As I am not an appliance repairman, I am not sure where to start with the siphon method of correction like the original poster described.  John
