Jim for Model Number FPHD2485NF1a the Frigidaire dishwasher I'm working on gets to the heated dry cycle then flashes PF. My first thought would be the circuit breaker is getting bad and it can't take the load the heater draws, or the heater relay on the board is getting week?
Answer Jim, the heater could be drawing too much amperage and can be tested for resistance. The heater 154825001 should read 16 ohms of resistance. If the heater tests good, and the circuit breaker is not tripping, you may want to check the wiring connection at the terminal housing. If the wire connections are secured properly, then the failure would be with the control board 5304514670. Read More... Answered by AppliancePartsPros.com | Friday, August 23, 2019
