Bosch Check Valve 00165262 OEM Part

Guide to Replacing the Dishwasher Pump Check Valve

When a dishwasher struggles with proper drainage, replacing the pump check valve might be required. This part plays a crucial role by stopping water from returning into the machine after being expelled. Located within the drain line, between the pump and the drain hose, the check valve ensures water moves in one direction only—out of the dishwasher—thus preventing backflow.

The Bosch dishwasher pump check valve is an authentic OEM component compatible with Thermador and Gaggenau dishwashers as well.

Replacing the check valve can address several common issues:

- Accumulation of water at the bottom of the dishwasher after a cycle
- Sluggish or incomplete draining of water
- Leaks or drips from the drain line or surrounding the check valve
- Unpleasant odors emanating from the dishwasher due to stagnant water

If any of these problems are present, consider replacing the check valve to maintain optimal dishwasher performance.
