Use this component when your dishwasher fails to clean dishes efficiently. It fits models from brands such as Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. Whirlpool also produces parts used in Sears-Kenmore and Ikea appliances. The pump and motor system in the unit directs water through this spray arm.
