The Pump Housing is an OEM part for Whirlpool dishwashers. As a central component, it contains the circulating pump that drives wash water through spray arms for thorough cleaning.
Symptoms of a bad pump housing include:
- Puddles or leaks from under the dishwasher main unit
- Limited or no water pressure to upper and lower spray arms
- Water that does not properly drain at the end of a cycle
- Drying issues caused by residual water collection
Causes can be cracks that develop from regular pump cycling stresses over time, or impact damage compromising seals and gaskets.
This OEM Whirlpool part is also compatible with some KitchenAid, Jenn-Air, and GE dishwashers.
