Daren R Bellevue , NE November 24, 2017 F20 Fix F-20 with a new water inlet valve and water level pressure switch. Was fast and easy, once pulled out from wall and water lines removed. I think I could have talked my 12 year old through it. Works like new now. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
