Part WPW10491331 Dishwasher Lower Wash Arm Assembly
Purpose
Rotates and sprays water to clean dishes.
Details
The WPW10491331 is a genuine OEM lower wash arm assembly (also known as a spray arm) for Whirlpool, KitchenAid, and Maytag dishwashers. This component is situated at the bottom of the dishwasher tub and uses water pressure to rotate, distributing water and detergent evenly throughout the wash cycle. If the spray arm is cracked, warped by heat, or if the tiny nozzle holes become clogged with hard water deposits, your dishwasher will fail to clean dishes effectively. A damaged arm can also lead to leaking or unusual knocking noises if it strikes other components. Replacing this part ensures proper hydraulic pressure and full coverage for a thorough clean.
Included Items
Lower spray arm assembly; no tools required for snap-on installation.
