ABT72989204 Genuine Wash Pump Casing Assembly Including Heater for LG Dishwashers, LG Dishwasher Heater Casing

This genuine LG casing assembly, part ABT72989204, houses the dishwasher's wash pump and comes with the heater included. Because the heater is part of the assembly, a failed heater on these machines is fixed by fitting the whole casing. We don't have a list of the LG dishwasher models it fits, so compare ABT72989204 with the number on your old casing or check your model number with us before ordering.

LG dishwasher not heating or leaving dishes dirty?

The wash pump pushes water up to the spray arms, and the casing is the housing it pumps through. With the heater built into this assembly, it also warms the water as it circulates. When the heater fails, the wash runs cold, cycles can drag on, dishes come out greasy or wet, and the dishwasher may show a heating error. A cracked casing or failed seal can also cause leaks under the machine. Test the heater for continuity and check the wiring plugs before ordering, since a loose connection gives similar symptoms.

Fitting the casing assembly

Switch the dishwasher off at the wall, unplug it and turn off the water tap. Sponge out water from the sump, then slide the machine out and lay down towels, as more water drains when the pump area is opened. Photograph the hoses and wiring before you strip it down. Fit the new casing with clean seals, reconnect everything, then run a short program and check underneath for leaks.

Not under this number. ABT72989204 is the casing assembly with the heater included, so it is ordered as one unit. Check the part number on your old casing or send your dishwasher model through the parts enquiry form to confirm it's the right one.
