Clean your Whirlpool Quiet Partner 1 dishwasher to wash away hard water minerals and other buildup. Whirlpool recommends cleaning the interior, exterior and the drain air gap. Clean the dishwasher as often as you want or particularly when you notice build-up. Regular cleaning may protect and prolong the life of the dishwasher and its components. You can clean your Quiet Partner 1 with common household ingredients.
Wipe the exterior of your Whirlpool Quiet Partner 1 dishwasher with a damp sponge or cloth. For extra cleaning power, use a squirt of liquid detergent on the sponge or cloth. If your model is stainless steel, use a stainless steel cleaner instead of water and soap.

Wait for the dishwasher to cool before cleaning the interior. Mix a paste of powdered dishwasher detergent and water, or use a liquid automatic dishwasher detergent. Apply either to a damp sponge and wipe the interior, including beneath the door, thoroughly to remove hard water mineral build-up. Run a normal cycle after cleaning.
Clean the drain air gap, located on top of the sink or near the dishwasher, when you either notice build-up in the drain air gap or if the dishwasher isn't draining well. Lift off the chrome cover and unscrew the plastic cap. Wipe away sediment buildup with a sponge or cloth and use a toothbrush to get in between crevices. Replace the chrome cover and plastic cap.
