KitchenAid Dishwasher Circulation Pump Replacement

This KitchenAid dishwasher circulation pump replacement involved a unit that was filling with water but not washing. The customer reported poor cleaning results and unusually quiet operation during the wash cycle.

The Issue

The dishwasher would fill and drain normally, but the spray arms were not operating with proper pressure. Dishes remained dirty at the end of the cycle, indicating a total circulation failure.

Diagnosis

Our inspection confirmed the pump motor was not generating pressure to drive the spray arms. In our experience across Hamilton, heavy mineral sediment can often accelerate wear on these internal seals, leading to the motor seized or electrical failure we found here.

Repair Performed

We replaced the faulty circulation pump assembly and inspected the filtration system. All water connections and seals were verified to ensure long-term, leak-free operation.

• Confirmed circulation pump motor failure
• Removed defective pump assembly
• Installed a new high-efficiency circulation pump
• Inspected internal filters and spray arm ports
• Verified full wash pressure and cleaning performance

Result

Wash pressure was fully restored and cleaning power returned to factory standards. The customer avoided the high cost of a full appliance replacement with this targeted component repair.
