Customer Questions and Answers for Dishwasher Thermal Fuse Kit by Whirlpool

Hello Kris, You need to troubleshoot the heating circuit. There are five components: the heating element, the high limit thermostat, the door switch, the control, and the wiring harness. There should be a tech sheet behind the kick panel which will show the wiring diagram. This should enable you to shoot through the circuit with an ohm meter. If it reads open from the control board, you will need to test each component individually. It will also guide you through a self diagnostic test that is necessary to run through to clear the code so the unit can run a cycle once repaired.
