William for Model Number SHX68T55UC/02 I replaced the inlet valve as I was getting a water tap code. Ran the dishwasher now I’m getting an E20 code. Unplugged it for 15 minutes, checked the screen and sump area. Plugged it back in and the code still comes up. Ran the code and it’s a circulation pump? Any suggestions? I see this model has the pump and heater?
Answer William, with the power supply to the dishwasher turned off, the heat pump on the circulation motor 00753351 would need to be tested for resistance and it should measure 15.2 Ohms across any of the terminals for the heater. If the heat pump fails the test, it would need to be replaced. If it has the correct resistance, the main power control 00752739 would need to be replaced. Read More...
