The Sump Assembly is an OEM part for Bosch dishwashers. It collects and channels water to the pump, ensuring proper circulation and drainage during the wash cycle.
Over time, the sump assembly can become clogged with debris, suffer damage, or wear out, leading to compromised performance. Causes of a bad sump assembly include buildup of food particles and mineral deposits, physical damage from sharp objects, or wear from continuous use.
Symptoms of a bad sump assembly include:
- Water not draining properly from the dishwasher
- Persistent leaks or pooling of water at the bottom
- Unusual noises during the wash cycle
- Dishes not being cleaned effectively due to poor water circulation
This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.
