Whirlpool Lower Wash Arm Support WPW10077898 OEM Part

This gray plastic Lower Spray Arm Hub measures 3 inches by 1.5 inches and is specifically crafted to enhance dishwasher efficiency when dishes are not properly clean. It fits a range of brands, including Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, Admiral, and is also compatible with select Sears-Kenmore and Ikea models.

As an original equipment manufacturer (OEM) component, this part is intended for Whirlpool built-in dishwashers, securing the lower wash arm during operation.

Over time, normal use or mineral buildup may cause wear to the lower spray arm hub, potentially impairing its function.

Indicators that a replacement might be necessary include:
- The lower wash arm is loose or detached, disrupting proper rotation.
- Obstructions caused by mineral deposits or food particles within the hub, affecting arm movement.
- Unusual sounds, like clanking or vibrations, emanating from the lower basket area.
- Ineffective cleaning of the lower rack, resulting in food residue post-cycle.

To maximize performance, it is advised to replace the Spray Arm Seal with the part number WP8268340 as well.

This hub also fits specific KitchenAid, Jenn-Air, and Kenmore built-in dishwasher models.
