Help get an error code f21 on my whirlpool. I have new pump and i cleaned the hose, changed the pressure switch on it and still stop on rinse cycle
Wow, one of those should have fixed it. The diagnostics on this model are terrible, as you are finding out. If you are sure the hoses are cleaned out and there is no blockage I can only suggest you change out the control unit, but only because that’s the only thing left, not because it makes sense to do so.
