This dishwasher repair guide explains how to replace the dishwasher door seal—also called a tub gasket—if water leaks through the dishwasher door. Also replace the door seal if it becomes brittle or is no longer pliable, or if you see cracks or tears in the seal. Make sure to use the manufacturer-approved dishwasher part when replacing the dishwasher tub gasket.
This repair guide and video shows how replace the door seal in Kenmore, Whirlpool, KitchenAid, JennAir, Maytag and Amana dishwashers. You also can use the same basic procedure to replace the door seal in some GE, Frigidaire, Electrolux, LG and Samsung dishwashers.
