How to replace a dishwasher vent and fan assembly

How to replace a dishwasher vent and fan assembly

This DIY repair guide gives step-by-step instructions for replacing the dishwasher vent and fan assembly. The vent opens during the drying cycle, and the dishwasher fan exhausts hot air through the vent opening at the bottom of the dishwasher door. If the dishwasher fan fails, the control panel goes blank and the dishwasher stops in the middle of the cycle. Replace the vent and fan assembly with a manufacturer-approved dishwasher part.

Use these steps to replace the vent and fan assembly in Kenmore, KitchenAid, Whirlpool, Maytag, Amana and JennAir dishwashers. You also can use the same basic process to replace the vent and fan assembly in some GE, Frigidaire, Electrolux, LG and Samsung dishwashers.

Instructions

  1. 01.

    Shut off electrical power

    Unplug the dishwasher or shut off the house circuit breaker for the dishwasher.

    To verify that power is disconnected, make sure the control panel doesn’t light up when you press a control button or the power button.

    Tip: If you want to confirm that the fan is the problem, do steps 1 through 4 and 6 through 8, skipping step 5. If the control panel lights up with the fan unplugged, the fan is the problem.

    Remove the outer door panel and control panel

    With the dishwasher door open, remove the Torx screws from the inner door panel. Support the outer door panel with one hand as you remove the final 2 screws so the outer door panel doesn't fall.

     Separate the outer door panel and control panel slightly from the inner door panel and rest the outer panel on the floor while you disconnect the user interface control wire harness from the control panel.

     Pull off the outer door panel and control panel.
