LG Pump Casing Assembly (ABT72989202)

The pump casing assembly is the housing that contains the dishwasher's drain pump motor and impeller. It draws water from the tub and forces it through the drain line to remove dirty water during the drain cycle, working in coordination with the control board to manage water flow at the right time and pressure.

Pump casings can fail due to debris like food particles or mineral deposits clogging the impeller, cracks from freezing water in cold environments, corrosion from prolonged water exposure, or wear on the motor bearings inside the housing. Over time, internal damage can reduce pump pressure, cause leaks at connection points, or prevent the pump from spinning entirely.

Watch for these signs that your pump casing may need replacement:

- Water remaining in the tub or not draining completely after the cycle ends

- Slow draining or water backing up into the dishwasher during operation

- Leaking water underneath or around the pump area during the drain cycle

- Unusual grinding, squealing, or rattling noises coming from the pump during drainage

- Humming sound from the motor but no water movement or weak drainage

- Burning smell or visible corrosion around pump connections

- Error codes or control board signals indicating pump or drain system failure
