Unplug your appliance from its power outlet to disconnect the supply of electricity. Disconnect the gas supply to gas appliances before continuing to step 2.
Locate the thermal fuse in residential washers or dryers by removing the bottom toe or back panels. Remove the bottom toe panel of your dishwasher to access the thermal fuse. Use a screwdriver to remove the screws that hold the panel to the appliance. Some appliance panels are held in place with metal clips; apply pressure to these clips with a flathead screwdriver or putty knife to free the panel.
Locate the thermal fuse among your appliance's exposed components. Look for a strip of white plastic with two connected wires. This is the appliance's thermal fuse. Disconnect the two wires from the thermal fuse by gently pulling on them.
Note the small screw at the center of the thermal fuse. Remove the screw to free the faulty thermal fuse. Discard the faulty thermal fuse, but reserve the small screw for use in step 5.
Hold the replacement thermal fuse to your appliance so that the screw hole in the thermal fuse is aligned with the screw hole in the appliance. Insert the small screw that you reserved in step 4 and tighten it with your screwdriver to secure the replacement thermal fuse to your appliance.
Attach the two wires to the new thermal fuse to complete your thermal fuse replacement.
