Tom for Model Number SHE43R55UC My dishwasher stopped cleaning the dishes and took forever to complete a cycle. This seemed to be due to the heater not working. The local repair guy came a diagnosed it and says the heater is bad. I bought a new one, replaced it, and the problem persisted. I checked the control board output and it was delivering 120V when heat was supposed to be running, so was pretty confident the problem wasn't the controller. The only thing left that seemed like it could be holding off the heater was the flow switch (which is new with the new heater) so I opened everything up again and bypassed the flow/pressure switch in the heating circuit. The heater now runs, finishes in normal cycle time and the dishes are much cleaner. So, is it possible I have two heaters with two bad flow switches, or is it likely that the circ pump is degraded and not delivering enough pressure to make the water flow switch reliably. The water is definitely being sprayed into the washer through the arms and they are moving... Is there anything else that could be preventing the flow switch from closing to allow the heater to run? I took the whole heater, pump, drain assembly apart and checked for blockages and found no problems.
Answer Hello Tom. It is possible you got a bad heater. However, you will need to check your wiring first and make sure it is good. Read More... Answered by AppliancePartsPros.com | Thursday, January 7, 2016
