Customer Questions and Answers for Check Valve by Bosch

The Check Valve is an OEM part for Bosch dishwashers. It prevents the backflow of water into the dishwasher after it has been drained, ensuring that dirty water does not re-enter the appliance and contaminate clean dishes.

Causes of a bad check valve can include blockages from debris or food particles, wear and tear over time, or damage from improper installation or handling. These issues can impair the valve's ability to effectively prevent backflow.

Symptoms of a bad check valve include:

• Water not draining properly from the dishwasher
• Dirty water pooling at the bottom of the dishwasher
• Foul odors coming from the dishwasher
• Residual water remaining in the tub after the cycle ends

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.
