Part 12008381 Circulation Pump and Heater Assembly
Purpose
Circulates and heats water for thorough cleaning cycles.
Details
The 12008381 is a genuine OEM "heat pump" assembly used in premium Bosch, Thermador, and Gaggenau dishwashers. This highly integrated component combines the circulation motor and the flow-through heating element into a single unit. It is responsible for pressurized water distribution to the spray arms while simultaneously elevating water temperature for effective sanitation and drying. A common failure point for this part is the integrated heater, which often triggers the "E:09" error code on the control display. Other symptoms of failure include noisy operation due to worn motor bearings, poor cleaning results, or a failure to start the wash cycle. Replacing the full assembly restores the mechanical and thermal performance of the appliance.
