This drain pump assembly is responsible for expelling used water from the dishwasher tub during the drain cycle. It uses an impeller driven by a small motor to push water out through the drain hose.

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.

Replacement spray arm assembly that installs in the dishwasher tub to restore water distribution. Needed when the original is cracked, worn, or missing.

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. 

This is the cap that seals the rinse-aid dispenser reservoir on the inside of the dishwasher door. It threads or snaps into place to keep rinse aid contained until it is dispensed during the rinse cycle. Replace this cap if rinse aid leaks out prematurely, the cap is cracked or warped, or dishes are coming out spotted due to improper rinse-aid dispensing.

Spring-style hose clamp secures water and drain hoses to fittings, preventing leaks. Replace when connections loosen or clips lose tension. Confirm fit with your model number.
