The Circulation Motor and Heater Assembly is an OEM part for Bosch dishwashers. It includes both the circulation motor, responsible for moving water through the dishwasher during the cleaning cycle, and the integrated heater, which raises the water temperature for effective cleaning and drying.
Symptoms of a bad Circulation Motor and Heater Assembly include:
- Dishwasher fails to clean dishes properly
- Water does not heat up, leading to poor drying results
- Unusual noises during the cycle
A bad part can result from several causes, such as electrical failures, mechanical wear and tear, or blockages in the system that prevent proper water circulation or heating.
If you notice any of these signs, it's time to replace the circulation motor and heater assembly. This OEM Bosch part can also be used on Thermador and Gaggenau appliances.
