Brad D Mission , KS November 30, 2017 Appliance: Model KENMORE HE2 WASHER F20 error code. Replaced the water inlet valve. Suspecting it was a sensor issue and generally electronic issues just completely quit working, not working sometimes. I heard that the seals in the water inlet valve can begin to fail (not electronic, explaining why it would work sometimes and others not. It was great fixing the problem myself.
