Whirlpool power surge
« on: December 06, 2020, 11:37:24 PM »

Hello all,
Washer is Whirlpool
Model #: WFW75HEFW0

Never had issues before. Recently had a power outage with the power flickering off and on 6 times and then a power surge when it was returned. It damaged a radio, 6 light bulbs, and the washer.
The washer was making a high pitched buzzing sound while plugged in but not turned on. Unplug the machine , no noise, plug it back it and immediately buzzing sound. The dial and mode selectors are fully responsive , the door locks and unlocks and when you start a cycle it locks and then nothing ever happens. Not throwing error code. Always buzzing sound throughout all of this.
I have tried unplugging for several minutes and plugging back in.
The sound appears to be coming from the stator? But could be motor.
Thoughts or suggestions? Is it total junk now?

There's a tech sheet inside your machine that will help in troubleshooting.

It would be useful to ascertain exactly where the noise is coming from.  A 3 foot long 1/2" diameter rubber hose can be used like a stethoscope to zero in on the noise that is occurring at all times when washer is plugged in.

Noise could be drain pump.  If washer pressure switch determines water is too high, pump will run until forever which usually means pressure switch is bad.  My first inclination though, is that your electronic control board W11201274 has gone bad as they are sensitive to "dirty" power.

Check the in-line power filter - look at schematic and follow the power cord to the board there should be an inline power filter that went bad.
