The Impeller Jug is an OEM part for Bosch dishwashers. Located inside the wash chamber, the impeller jug is responsible for evenly distributing water throughout the dish rack during the wash cycle. It features strategically placed holes and channels that work with the spray arms to direct water flow and ensure all dishes receive thorough coverage.
Symptoms of a bad impeller jug include:
- Incomplete cleaning even on short or heavy wash cycles
- Dirty dishes remaining at the end of the cycle
- A buildup of food or grime deposits inside the wash chamber
- Off-balanced or excessive noise levels during washing
Causes of failure can be mineral or scale buildup inhibiting water flow, cracked or damaged casing allowing leaks, or worn impeller fins no longer efficiently dispersing water. Over time, hard water deposits and normal use can degrade performance.
This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore dishwashers.
