The electrical issue seems to have gone away...well at least it hasn't returned since I last spoke of it.
Did you have any more problems with the electrical issue? Our machine just started doing the same thing today. We had joked about plugging it into a power strip that could easily be turned off to reset the machine since the plug is behind the machine & it isn't very practical to slide the washer out for every load. I'm glad to know our "silly" idea wasn't so silly after all.
Thanks for your posts!
I did a lot of reading on the computer and could not really find a answer to my fix. I was leading toward the main control box in the left rear corner of the washer. (Part is not cheap). I decide to try to open box up and tap relays and see if would reset. I had to undo several screws and tie wires to get room to pull the cover off of control box. Once inside I tapped the relays and plugged back in, didn't change. I unplugged the power cord again and pulled the yellow top plug off which has two wires red and yellow. I then plugged washer in and front control board lit up but no drum light. I then unplugged power cord and attacked the yellow plug again. When I plugged power in again drum light was on I then shut machine off and in 4 minutes the drum light went out. Tied several times before reassembling. Hope this helps someone because LG support was worthless call for service callThe electrical issue has returned just once. So I was glad the power strip was still there.
IIRC, I can induce the electrical problem by manually spinning the drum with the door open. It's as though spinning the drum induces enough energy in the coils and hall effect sensor to confuse the unit. I've somewhat concluded in my head that the issue somewhat was caused by the bad bearing causing more rolling resistance to the drum than it expected and that also confused the unit. That being said, the unit could have been manually spun the one time mentioned above, but I'm not sure as I wasn't there.
How does your unit spin? Any excessive noise or play in the bearings? Might be worth pulling the back cover to see if the seal is perhaps leaking.
Wish I had better answers. Good luck.
Here's a tip: My LG Washer stopped working today and I tried everything I knew to find out what the problem was but nothing worked. None of the digital display was on, just the light inside the washer that would not turn off. This was very strange, if it was the circuit breaker the light certainly would not be on. I could not find any information on this on the internet so I am going to share this tip with you.
My son works at a big home improvement store and I asked him if he knew what the problem was and he found out that if you unplug your washer and push down the power button for 5 seconds and let go, then push down the start button for 5 seconds and let go, then plug the washer back in, you should be able to push the power button as you would to run a load and the washer should work again. It's like a reboot for the washer. I hope this helps anyone with the same problem out there, it saved me an expensive visit from an appliance repair person.
I had the exact same situation for another customer and with some help from LG, we replaced the PCB, display board and the power filter to try and resolve the problem. Nothing worked. That was over a year ago. LG tech support wanted to have the machine at their repair facility to see what's going on but the higher ups in LG customer service didn't want to buy the customer a new machine since it was way out of warranty. So the customer has to keep unplugging the unit to reset the controls so she can use the washer. Strange but once the machine finishes it's cycle, the controls will still work for at least 10 minutes before the display board freezes up.
Now that the same situation has come up on your machine, I'm suggesting this. Replace the wire harness that connects the display board to the PCB. That part number is 6850ER2002N. I suspect that there is a short in the wire harness since it uses tiny wires. Let me know if that resolves the issue. I'm really curious!!!
This seems to have worked after 5 tries for my 10 yr old washer that started doing this. Model WM2501HWA. Thanks!Here is THE solution I tried that WORKED with my LG washer (a WM2501HVA) - to finally cut the drum light off: A) Completely cut the power to the unit - either by unplugging it or by switching it off the breaker box; B) Wait just 20 seconds or so and while the power to the unit is still cut, press and hold down the power switch for 10 seconds and then let your finger back off; C) Cut the breaker box on / or plug the unit back in (whichever you did to cut power). D) Turn the unit back on by normally pressing the power switch (but this time don't keep it held down) - and the unit should turn back on - and don't panic - as the drum light will come back on; E) Leave the unit on and just wait until the timer censor automatically cuts the unit off, and the drum light should also cut off, and STAY off. Important: You may have to try the same sequence above (A-E) a second time - as it did not work for me the first time, but the second time it was successful (which means you might need to try this even a 3rd or 4th time). Also, the first time I powered turned the power to the unit back on (I cut the power and then turned it back on at the breaker box), the unit automatically powered on without me turning on the power button. If this happens, just do step E above. Hope this helps someone!
