Okay so i have a 4 year old Hotpoint Ultima dishwasher FDFAO 32121K so all of a sudden have the displaying F15 which is pump blockage so i have stripped the pump down and check hose and pump for blockages or anything else nothing found, flap moves in the pump outlet and nothing blocked while i was there i check the resistance of the motor it was 83 ohms. i also keep seeing the filter blocked symbol on the display at the turn on stage.
so am i looking at a faulty pump or a suspect PCB, to added to this when it started in was on the 65 degree wash but the duo 50 wash worked fine all the way to the end and within a week its now not getting past the initially pump out before the first fill on all programs…
also occasionally get a F2 fill but works on other programs. but now not working at all.
Help please.
