Rebecka W for Model Number wm0642hw I have a FE and a PE code on my washer, I recently had a drain back up, could this have caused the error, and would I have to replace both water valves?
Answer Rebecka, A backed up drain could potentially cause the unit to come up the error codes. The PE is a pressure sensor error and the FE is overflow error. If the water backed up into the washer it could have gotten debris into the pressure hose which would cause this issue. If that is not the case then you will want to replace the pressure switch which would be out of order. Read More... Answered by AppliancePartsPros.com | Wednesday, May 22, 2013
