4055993572 Genuine BLDC Wash Pump for Electrolux Group Dishwashers, Brushless Circulation Pump for Dishwasher Not Washing

Genuine Electrolux washing pump, part 4055993572, with a BLDC (brushless DC) motor. In a dishwasher the wash pump, often called the circulation pump, pushes water up to the spray arms during every wash and rinse. A brushless pump is driven electronically by the main board, which can adjust its speed through the cycle. Match 4055993572 to your old pump or your parts list, as pumps differ between models.

Dishwasher not washing or spraying properly

If the wash pump fails, water comes into the dishwasher but never gets thrown around the tub, so dishes come out dirty and the cycle may stop with a fault code. A brushless pump can also stall if broken glass, seeds or labels jam the impeller, and a grinding noise usually means something is caught or the bearings are worn. Before replacing the pump, clean the filters, check the sump for debris and turn the impeller by hand where you can reach it. A pump that is clear but still won't run, or one leaking from its housing, needs replacing.
