Dishwasher not draining? The drain pump may be the cause

At the end of each wash and rinse, the drain pump pushes the dirty water out through the drain hose. If the pump fails, water sits in the bottom of the tub, the cycle stops with an error, or dishes come out sitting in murky water. A pump that hums but doesn't empty may be jammed by broken glass, a fruit label or a bone fragment, while one that stays silent may have an open winding. Before replacing it, clean the filters and sump and check the drain hose isn't kinked or blocked at the sink spigot.

Swapping the pump

Switch off at the wall and turn off the water tap. Bail out or towel up any water left in the tub, then lay towels down, as more water will come out when the pump is released. Note how the pump is clipped or twisted into the sump and photograph the wiring plug. Fit the new pump with its seal properly seated, then run a rinse program and check underneath for leaks.

Questions about this part

How do I know it is the pump and not a blockage?

Clear the filter and sump first and check the drain hose. If water still won't pump out and you can hear the pump humming, or nothing at all, the pump is the likely fault. A multimeter test across its terminals can confirm an open winding.
