ABT72989207 Genuine Wash Pump Casing Assembly with Built-In Heater for LG Dishwashers, Dishwasher Heating Element Housing

Genuine LG part ABT72989207 is the wash pump casing assembly for LG dishwashers, supplied with the heater built in. In this design the heating element sits in the casing that the wash water flows through, so the water is warmed as the pump circulates it to the spray arms. No model list is on file, so match ABT72989207 to the label on your old casing or your dishwasher's parts list before ordering.

LG dishwasher not heating water

If the heater in the pump casing fails, the dishwasher still runs but the water stays cool. Dishes come out greasy or wet, detergent tablets may not dissolve fully, and cycles can run much longer as the machine waits for a temperature it never reaches. Some LG models show a heating error code when this happens. A heater that has shorted can also trip the safety switch as soon as the heating stage begins. Leaks from the casing, or a cracked housing, are another reason to replace the assembly.

Replacing the pump casing

Switch the dishwasher off at the wall, turn off the tap and pull the machine out carefully. Have towels ready, as water sits in the sump and hoses. Photograph the wiring and hose connections, then transfer them to the new casing exactly as they were. Check the seals are seated properly and run a short cycle while watching for leaks. If you're not confident with the wiring, use a qualified technician.
