Customer Questions and Answers for Diverter Valve Seal by Bosch

The Diverter Valve Seal is an OEM part for Bosch dishwashers. This rubber seal sits within the diverter valve assembly to protect internal components from liquid, debris and other particles during operation.

Causes of a bad diverter valve seal can include degradation of the rubber material over time from continuous exposure to hot water and detergents. Small cracks or splits can develop and widen.

Symptoms of a bad seal include:

• Water or other leaks originating from the diverter valve area
• Loud squealing or squeaking sounds during certain wash cycles
• Incomplete fills or sprays from spray arms as water diverts incorrectly

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