Hello, I got this washer second hand and all of the buttons for the extra options and childlock do not work( I can feel the switch making) I am also having trouble with the soil level button. It will work intermittently about 20% of the time. The unit still functions and washes but I do not have all of the extra features. I was wondering if it is the display brd or the control brd. Is there anyway to test the circuit brd like in a service mode or do I just need to replace the brd. I am assuming that if it has those buttons it has those options.

My wife and I just received this model washer from my mother-in-law with the warning that the "buttons stick" and need to be pushed several times before working. Which part do I need? F110 or F210? Thanks!!

Someone asked the exact same question. My unit tripped a breaker in my basement also. It seems strange because it must have done it right at the end of a wash. (clothes were washed and spun.) Anyway, no lights at all on control panel. I removed the washer cover and checked the circuit board in the back and there appears to be no burns on the circuit board. (It was replaced a year ago anyway by a service company) I removed the control board in the front and checked it also. It looks fine as I also removed both circuit boards, and neither showed any sign of burns. It has 3 harnesses. One with 3 wires, and 2 with @ 10 wires each. All 3 are thin -1 is blue and 2 are white. The small white one has 3 wires and there is power (120v) at this point when the machine is plugged in. Again, no lights at control panel whatsoever. Thanks for any help you can give me.

I have two buttons missing on the control panel( rinse +spin and extra rinse). Do I have to purchase the control panel or see it more simple?

My washer stopped suddenly and tripped the breaker. I flipped the breaker back on and there are no lights. Nothing happens when I press the start button. The breaker has not flipped off.

I am pretty sure I need part number AP4457379 but may need another board. Can not even begin the QC check. Have LE code alot which requires unplugging, sometimes draining water. Periodically can not switch to another mode besides normal. Can not do customer settings.
