WPW10330588 Whirlpool Lower Wash Arm

The Lower Wash Arm is a genuine replacement part designed for various Whirlpool dishwashers, including models from brands such as Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. Additionally, this part is suitable for certain Sears-Kenmore and Ikea dishwashers. Located at the bottom of the dishwasher, this component plays a crucial role by rotating to evenly distribute water and detergents over the dishes and utensils placed on the lower rack.

Factors that might lead to the malfunctioning of the lower spray arm include the accumulation of mineral deposits or sediment, which can prevent it from rotating, wear and tear on its internal bearings from extensive use, or damage from physical impacts.

If the lower spray arm is not functioning properly, you might notice several issues: dishes on the lower rack may not be cleaned thoroughly, there could be unusual grinding or scratching sounds due to hindered rotation, the arm might detach from its mounting during operation, or dishes may not be fully coated with rinse agents.

This replacement part is also compatible with dishwashers from Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore.
