Lance for Model Number WFW8400TW02 My WFW8400TW02 washer shuts off by itself right before the draining or spinning process of a cycle. The cycle finishes when there are no clothes in the washer. The error code F20 is shown even though the pump filter was cleaned. The pump has a loud noise when draining. What is the problem with the washer? Thank you and have a nice day.
Answer Lance, The F20 error is detecting a possible pressure switch fault. Including water valves in no water is entering or pressure hose possible pinhole. Even check the connector on the pressure switch itself and the control where the pressure switch harness plugs into. You should have a tech sheet with your unit that gives you testing info on that specific error code. Read More... Answered by AppliancePartsPros.com | Wednesday, October 6, 2021
