LG wm2010cw (Tromm) front load IE error - drain pump stuck on

11 posts in this topic

My front load LG washer has been working great since I bought it new 2 years ago (just now beyond the extended warranty). Last week a heavy bath mat caused an unbalanced load and the washer shook quite violently when it was spinning before I shut it off. Ever since, the washer displays an ie error after trying to fill for 10 minutes or so.

I've followed the recommended steps to fix the IE error, checked the inlet hoses, cleaned the inlet filters (weren't very dirty), and even tested the fill level switch inside the machine. all checked out fine.

I believe the problem has to do with the drain pump being stuck on during the fill cycle. As the washer is filling with water, it is constantly being drained so it never fills up. As a test, I deliberately clogged the drain trap with a rolled up sock and the cycle continued without any error, although I stopped it since it obviously took forever to drain. It is not a drain siphoning problem - the drain is fed into a standpipe above the top of the washer and it has plenty of room to breathe. I also ran through the diagnostic test in the LG service manual and during the test it sounds like the drain pump is running the entire time.

Anyone familiar with this problem or have any suggestions? Could it be a wire was disconnected somewhere while it was shaking? I've got the top and back panels off the machine now but I'm not sure where else I should look for the problem?

if you disconnect the pulg to the pump does the machine fill up to the proper level and start to wash or does it wash for a minute and then start to fill again...check the pressure tube from the switch to the tub and make sure it doesnt have a pin hole in it.

If that looks good and the machine fills to the proper level and performs normally in the wash cycle when the pumps disconnected from power then your main board got messed up during the violent shaking

Today I disconnected the ground wire from the pump and ran another cycle. The water filled to the proper level and started washing with no IE error. At the same time, I hooked up my multimeter to the drain pump wire (brown) at the back of the main board and it read 119V throughout the entire cycle. Eventually it gave me an 'OE error' after the first wash cycle finished and the water level didn't go down after a few minutes. I guess that means the main board will have to be replaced?

Enter DIAGNOSTICS MODE by doing the following:

1) Press & Hold the SPIN SPEED & SOIL LEVEL buttons

2) Then press/release the POWER BUTTON.

3) Wait until the door locks (single click sound)

4) Read the SOFTWARE VERSION CODE in the display.

If the software version is: "IU:00"

You'll need a new MAIN BOARD (EBR43249701) and three new STRUTS (383EER3001F)

This only applies to the WM2010CW washer with SERIAL NUMBERS *up to* 906KWxxxxxx

A flaw in the ***software*** caused excessive spin-vibration----which also usually damaged the STRUTS.

NOTE: The new MAIN BOARD will have a ***software version*** of: IU:03

Well I just called LG Canada and explained my problem. I was happy to see that LG Canada has a 3 year warranty on the controller (as opposed to 2 years in the US). Unfortunately I still have to pay $100 for a service call so they can confirm the problem. I am still wondering if the problem may be something other than the control board? Is there any other component that would trigger the controller to keep the drain pump running?

Thanks John. I just did what you suggested and I can confirm I have version IU:00 and my serial number is 906KWSB03xxx

I also failed to mention that when I first checked behind the machine after removing the back panel, the first thing I noticed was that one of the struts had completely detached (I assume because of the heavy vibration). It wasn't hard to slip back together.

Does this mean I should get these components repaired free of charge. It is just beyond 2 years since I bought the machine so the labour warranty expired 1 year ago.

In the US market...

A call to the CUSTOMER SERVICE REPRESENTATIVE (and ask to speak to their *supervisor*) usually results in a free repair for a documented (known) problem such as yours.

Good luck!

Called customer service again and was told that they have no records of any problems with the the software for the main board of this model washer. They're still going to make me pay for any labour.

The LG technician just left. He replaced the control board with a new one (software version IU:03 just as you said) and it's working great again. He thinks the drain pump relay somehow got jammed closed in the old control board, which he let me keep. He still claims there was no service bulletin for this machine despite all the evidence I showed him that there is one, but he was nice enough not to charge me labour since I had already taken the machine apart and correctly diagnosed the problem (but I was charged $95+tax for the service call).

Thanks guys for all your help!

The STRUTS/DAMPERS should've been replaced as well.
