WPW10077898 Whirlpool Lower Wash Arm Support

This Gray Plastic Lower Spray Arm Hub measures 3 inches in length and 1.5 inches in width. It is designed to improve dishwasher performance when dishes are not being cleaned adequately. It is compatible with various brands including Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, Admiral, as well as some Sears-Kenmore and Ikea models.

The Lower Spray Arm Hub is an original equipment manufacturer (OEM) replacement part specifically for Whirlpool built-in dishwashers. Its primary function is to hold the lower wash arm in place during the wash cycle.

The deterioration of a lower spray arm hub can result from normal wear after many wash cycles or from mineral deposits that accumulate, which can damage the connecting surfaces over time.

Signs that the lower spray arm hub may need replacement include:
- The lower wash arm becoming loose or detached, preventing it from rotating correctly.
- Blockages from mineral deposits or food particles in the hub, which hinder arm movement.
- Unusual noises, such as clanking or vibrations, coming from the lower basket.
- Inadequate cleaning of the lower rack, leaving food residue after the wash cycle.

For optimal performance, it is recommended to also replace the Spray Arm Seal with part number WP8268340.

This part is also suitable for certain KitchenAid, Jenn-Air, and Kenmore built-in dishwasher models.
