Ken for Model Number MHN30PDBWW0 Hi Guys, A follow up on my F20 code problem. I tried the procedure with the quick wash button, but could not get it to clear. I rechecked the fill switch hose but there is no obstruction or any water left in the pump. Is there anything else that could cause that or am I dealing with a faulty control ? Thanks for the help, Ken
Answer Ken, this could potentially be a failed pressure switch W11417620, broken wire, or failed main control WPW10311189 (part has been discontinued by the manufacturer). The pressure switch can be tested for continuity from pin 21 to pin 24 then pin 21 to pin 22 while gently blowing into the pressure switch. There should be continuity. If there is, and there is not a broken wire, the main control has failed. Read More... Answered by AppliancePartsPros.com | Tuesday, October 26, 2021
