The Sump is an OEM part for Whirlpool dishwashers. It serves as the central component of the dishwasher's water circulation system, housing the pump and filters. This part collects water during the wash cycle, which is then pumped through the spray arms to clean the dishes. The sump also traps food particles and debris, preventing them from recirculating and ensuring dishes come out clean.
Symptoms of a failing Sump include:
- Poor cleaning performance, with dishes still dirty after a cycle
- Water not draining properly or remaining in the bottom of the dishwasher
- Unusual noises, like grinding or humming, indicating pump issues
- Leaks under the dishwasher due to cracks or seal failures in the sump
Causes of a bad sump often include regular wear and tear, accumulation of hard water deposits, or blockages from large food particles and debris. Additionally, the seals can degrade over time, leading to leaks.
This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
