4055978425 Genuine Drain Pump LELI 13mm for Electrolux Group Dishwashers, Dishwasher Waste Water Pump

This genuine Electrolux drain pump, part 4055978425, is listed as a LELI 13mm pump. It's the pump that empties the dishwasher at the end of each wash and rinse, pushing dirty water out through the drain hose. Electrolux sells several drain pumps that look much alike, so the LELI 13mm description and the number on your old pump are what to match.

Dishwasher not draining? Check the pump

At the end of each stage the control switches on the drain pump, which spins a small impeller to force water out through the hose. Faults show up as water sitting in the bottom of the tub after a cycle, a long hum or buzz during the drain stage, dishes left wet and dirty, or a drain error on the display. Before replacing the pump, clean the filters, make sure the drain hose isn't kinked, and check nothing like broken glass or a seed is jammed against the impeller. If all of that is clear and the pump still won't run, it's time for a new one.

Changing the drain pump

Switch off at the wall, turn off the tap and pull the dishwasher out of its cavity. Sponge out the water in the sump first, and lay towels down because more will come out when the pump comes off. Most pumps twist or unclip from the sump. Photograph the wiring, fit the new pump with its seal seated properly, then run a short cycle and check for leaks.
