Gaggenau Dishwasher Pump

Rear pump housing for the washer drain/pump assembly. Replaces the worn rear housing that supports the impeller and bearing, helping restore proper draining and reduce leaks or unusual pump noises when the housing fails. What it does:

• Houses and supports the pump impeller and bearing, forming the rear half of the drain pump assembly.
• Restores a sealed mounting surface to help prevent water leaks from the pump area.
• Helps re-establish correct water flow and draining when a cracked or worn housing impairs the pump.
• Addresses symptoms such as poor or no draining, water at the base of the appliance, or loud/grinding pump noises.

• Disconnect power and shut off water supply before starting; drain any standing water to avoid spills.
• Remove the washer access panels and pump assembly; transfer the impeller, seals, and any hardware as required.
• Inspect and replace pump gaskets/seals and the impeller if worn; tighten mounting fasteners to OEM torque where specified.

Dishwasher not spraying water or dishes staying dirty? The circulation pump motor distributes water to spray arms. Moderate DIY repair, about 3 hours.

Dishwasher not draining or water pooling at bottom? A cracked sump disrupts water flow to the pump. This housing restores drainage and prevents leaks.
