If your KitchenAid KUDC10XILB4 dishwasher isn’t starting, the thermal fuse may be bad and will need to be replaced. Here is a step-by-step procedure for replacing the thermal fuse:

1. Test the dishwasher for power

Before removing the thermal fuse, you will need to verify the dishwasher has electrical power. To do so, remove the kick plate located at the bottom of the dishwasher.

Once the kick plate has been removed, look underneath the dishwasher and locate the power cable that provides electricity to the appliance. Use a non-contact AC voltage tester to check the cord for power; if there is power, proceed to the next step.

2. Remove the front panel and control panel

On the backside of the dishwasher door, locate and remove the screws that hold the front panel and control panel in place. Once the screws have been removed, close the dishwasher door, then carefully pull the large front panel away from the dishwasher. Next, pull the control panel from the dishwasher while simultaneously disconnecting the wiring harness.

3. Check the thermal fuse

After you removed the front panel and control panel from the dishwasher, locate the two black wires leading from the thermal fuse. Check each wire with a non-contact AC voltage tester to determine if power is passing through the fuse; if one wire is still “hot”, but there is no power in the other wire, then the thermal fuse is bad.

4. Replace the defective thermal fuse

To remove the defective thermal fuse, you will need to first remove the plastic cover that conceals the fuse. This cover is attached to the underlying computer with several tabs. Carefully pry each tab loose, then pull off the cover to expose the concealed thermal fuse. Next, use a screwdriver to pry the tabs holding the fuse in place to the computer, and pull the fuse out toward you.

Next, remove the “hot” wire from the fuse, then remove the other wire from the fuse. The thermal fuse is now detached and can be replaced with a new part. Attach the new fuse to the wires and reinstall the components in reverse order from above.
