Dishwasher filling but not washing? The circulation pump may be at fault

During a cycle the circulation pump draws water from the sump and pushes it under pressure to the spray arms. If the pump fails, the dishwasher can still fill and drain as normal while the dishes come out dirty, unrinsed or coated in detergent. Other signs include a hum with no sound of spraying water, a loud grinding or rattling from under the tub, a burning smell, or an error code linked to the wash motor. Broken glass or a fruit pip stuck in the impeller can mimic a failed pump, so check the sump first.

Replacing the wash pump

Turn the dishwasher off at the wall, shut off the tap and pull the machine out from the cabinetry. Bail out the sump and lay towels down, as the hoses hold some water. Photograph the clamps and wiring plugs before removing the old pump. Use new clamps if the old ones are tired, and check every joint for drips on the first wash before sliding the machine back in.

Questions about this part

My dishwasher hums but won't spray water. Is it the pump?

Quite often. A hum with no spraying commonly points to a jammed or failed circulation pump. Check the sump and filter for glass or seeds first. If the impeller is clear and the pump still won't run, the pump itself is the likely cause.
