How to replace a dishwasher detergent dispenser

How to replace a dishwasher detergent dispenser

This DIY repair guide gives step-by-step instructions for replacing the dishwasher detergent dispenser. The dispenser in the dishwasher door houses the main wash detergent cup and the rinse aid compartment. A hinged cap covers the detergent cup until the electronic control board—or the timer, in some models—signals the cap's latch to pop open. During the last rinse, the rinse aid compartment releases a small amount of rinse aid. If you find any dispenser parts damaged or the dispenser doesn't open when activated during the cycle, replace it with a manufacturer-approved replacement part.

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