The Retainer is an OEM replacement part for Whirlpool built-in dishwashers. It is a plastic clip located within the lower wash arm assembly. This retainer securely holds the pivot hub bearing and ensures smooth oscillation of the lower wash arm during cycles.  

Causes of retainer failure commonly relate to plastic material degradation from regular heat and chemical exposures over many uses. Crack propagation weakens the clips ability to precisely position bearing elements.

Symptoms of an inadequate retainer may include:

• Grinding or scraping noises coming from the wash arm area
• Restricted movement or binding of the lower spray arm assembly
• Potential loose wash arm parts that could interrupt spray patterns  

This OEM Whirlpool replacement is also compatible with KitchenAid, Maytag, and some Sears/Kenmore dishwashers. 

This manifold channels wash water to the dishwasher's spray system for full coverage. Replacing a cracked or warped manifold restores proper water flow and wash performance while helping prevent leaks at the feed connection.

• Directs recirculated water from the pump to the spray arms/feed tube
