Jim for Model Number MHWZ600TW00 Washer does not stop filling. Eventually stops and flashes error code F20. Per various fix suggestions on your site, have checked that water is running correctly through both temperature hoses, replaced water inlet valve - didn't fix issue. Next put in new water level pressure switch - didn't fix issue. Your helps said to try adding a new electronic control board so did that - still same issue. So, far you are 0 for 3. Any additional suggestions? Thank you.
Answer Jim, it would be recommended that the pressure hose is inspected for any clogs as this could prevent pressure from accumulating and pushing into the pressure sensor. Commonly, detergent residue accumulates where the pressure hose connects to the tub. If there is not a clog, the hose would need to be checked for any pinholes by placing the hose into a bin of water, holding one end shut, and blowing air into the other end. If any bubbling occurs, the hose W11252474 would need to be replaced. Read More... Answered by AppliancePartsPros.com | Sunday, June 13, 2021
