Dishwasher Circulation Pump (Heat Pump)
The circulation pump (Heat Pump) utilizes a Brushless DC motor to drive the impeller. In this model, internal bushing wear or debris ingress into the impeller housing leads to a reduction in RPM, which prevents the unit from generating the necessary hydraulic head to reach the upper spray arms. Replacing this assembly restores full system pressure and ensures the heating element correctly maintains thermal targets for soil suspension.

Water Inlet Valve
Bosch dishwashers rely on precise water volume for the circulation pump to prime without cavitating. If the internal diaphragm or mesh filter of the inlet valve becomes restricted by mineral scale, the unit will not fill to the required level within the timed cycle. This low-water condition results in weak spray pressure and poor mechanical agitation during the wash phase.

Top Spray Arm Assembly
Specifically addressing the 'Top Rack' mention, the spray arm orifices can become occluded by calcium deposits or micro-debris that bypasses the filtration system. Furthermore, if the plastic weld on the arm integrity fails, it causes a 'pressure leak' where water escapes through the seam rather than the jets, resulting in zero rotation and poor cleaning of the upper basket contents.
