H0120400566 Genuine Wash Pump Heating Module for Fisher & Paykel, Haier Dishwashers DW60FC2X1 DW60FC4X1 DW60FC1W1 HDW13V1S1 HDW15V2S2 HDW15G3X

Fisher & Paykel DW60FC and Haier HDW dishwashers rely on this genuine wash pump heating module, part H0120400566, to both circulate and heat the water. It replaces H0120400178A. Listed models include the DW60FC1W1 and DW60FC2X1, the DW60FC4X1, plus DW60U2I1 and DW60UC2X, and from Haier the HDW13V1S1, the HDW15V2S2 and HDW15V3S1, and the HDW15G3X.

Dishes dirty or cold at the end of the cycle

This module combines the circulation pump with the heater, so one part does two critical jobs. The pump forces water up through the spray arms at pressure, while the heater brings the water up to wash temperature. If the heater fails, dishes finish cold and greasy and detergent may not dissolve properly. A failing pump shows up as weak or stalled spray arms, humming with little water movement, or dishes that are barely touched. Either fault can also trip the safety switch or bring up a heating or circulation error.

Changing the heater pump

Turn the dishwasher off at the wall and close the water tap. Pull the machine out of its cavity and lay towels down, as water sits in the hoses and sump. Photograph the hose clips and wiring plugs, then release the module and fit the new one the same way. Run a short cycle to check for leaks and heat.
