I have a customer with the above model LG washer. the original complaint was that it wouldnt turn on.
I went out and it appeared to be dead. no lights nothing when I pressed the start button.
So I unplugged it to check the connections. All looks good.
I plugged it back in, and it works fine.
She ran a cycle and said it completed.
She called back later saying it was dead again.
I went back, removed the top and noticed the red light on the board was on.
nothing happens when the power button pressed. Unplug it, plug it back in and it works fine. completes another full cycle. She said she is able to use it as long as she unplugs it and plugs it back in if it doesn't work.
The only thing I can think of is that something on the main board is weak and gets energized when its unplugged and plugged back in.
Any advice is appreciated.
