Background:

https://www.lg.com/hk_en/laundry/combo-w...

My washer dryer lives on my covered balcony and is covered by a plastic sheet for some protection. This I guess was not enough during a recent typhoon in my area, and I suspect it got wetter than it could tolerate.

What still works:

• The machine is still switching on when I turn the mains power on.
• The display comes on as expected.
• WiFi connectivity and the LG ThinQ app can see it successfully.
• I can run a diagnostic report in the ThinQ app and it says it’s 100% normal.

What is wrong:

• The chime it normally plays has a very elongated final note
• The physical and touch sensitive buttons are not responding
• The knob is not responding
• After running the diagnostic report in the app, the machine sounded like it was stuck in some sort of loop as the chimes it was playing were continuous and quite erratic
• No wash or dry cycles can be initiated

Video showing original symptoms:

What I’ve tried so far:

1. Left the machine unplugged for several very dry days. No difference.
2. Sourced a replacement knob controller unit (original EBR331191, replacement EBR339279) and display board unit (both EBR356611) and replaced. Machine power button works as expected, but the machine powers off if I start to twist the knob or press other buttons.
3. Video showing symptoms after replacing parts above:

I read it's typically dampers problem, makes sense to me, so I said hey, they are cheap, why not try it, but now when i have them home, I am surprised - the new ones look exactly the same as the ones in the washing machine, but the force needed to move them is like half of the originals...

Now I think I either bought wrong type or I am stupid for thinking new dampers should be harder to move... But I guess the old dampers are simply alright, no need to change them, they are nicely firm, look alright (I can return the new ones, so no problem)

Can someone help me decide what is it? Maybe even help me with some other suggestions what can cause washing machine to not do the last fast spin cycle and instead just spin slowly with pump running indefinitely, but only if the load is not balanced well? balanced load works without problem.

Thanks to all that might try to help me.
