My dishwasher will not heat the water or dry my dishes. Is this a thermostat problem or a heating element problem?
You will want to make sure that the water temp coming into the unit is at least 120 degrees and make sure that you are putting the unit on heated dry. If this checks ok then you will want to check the heating circuit of the unit. Make sure that the heater checks ok and that the thermostat is ok. Also check to make sure that there is 120 vac going from the control board to the heater assembly.
