Andrew for Model Number gdf620hmj2es All the dishwasher LED display lights show up and it does the correct cycles and drains but the water is not hot and it does not dry the dishes either. I took it out and tested the heating element and got 16 ohms. When I turned the power back on and ran the diagnosis tool for the heater I did not get any voltage readings coming into the heating element lead connections. Is the issue the Service Machine control? Have not taken it out and looked for the LED light flashing yet but was not sure what code to look for as well.
Answer Andrew, There is a thermostat that you will want to check to make sure that it is good. If it tests good for continuity then the issue will be the control board. Read More... Answered by AppliancePartsPros.com | Tuesday, May 5, 2020
