The Arm Spray is an OEM part for Whirlpool dishwashers. This component is crucial in the dishwasher's ability to effectively clean dishes, as it distributes water evenly throughout the unit during a wash cycle. Located beneath the upper rack, the arm spray rotates and sprays water at a controlled pressure and angle, ensuring that all dishes, regardless of their placement, are thoroughly washed.
Causes of a bad arm spray include clogging from food particles or mineral deposits from hard water, physical damage that can prevent it from spinning, and wear that reduces the effectiveness of the spray holes.
Symptoms of a bad arm spray include:
- Dishes remain dirty or spotty after washing
- Decreased water pressure in the spray
- Unusual noise during operation as the arm struggles to rotate
This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
