4055790549 Genuine Inner Sump Cover Non Return Valve for Westinghouse Dishwashers KEE27200IW

Genuine Electrolux part 4055790549 is the inner sump cover with its non return valve, listed for Westinghouse dishwashers. Our records tie it to model code KEE27200IW. The valve lets dirty water drain out of the sump and stops it flowing back in. Check the model and product number on your dishwasher's door label against the parts list, or compare with the old cover, to confirm the fit.

Dirty water flowing back into the dishwasher?

At the bottom of the wash tub, the sump collects water for the wash pump and the drain pump. The inner sump cover with its non return valve guides draining water out while a flap blocks it from running back. If the flap sticks, tears or gets jammed with food, waste water can siphon or flow back into the tub. Signs include dirty water sitting in the base after a cycle, a sour smell, grit on clean dishes and poor wash results. Cleaning the filter and checking the drain hose loop are good first steps.

Fitting the sump cover

Switch off at the wall and turn off the water tap. Remove the lower basket and filters, then bail and sponge out any water in the base. On most models the cover is reached from inside the tub once the filters are out. Note which way the valve flap faces before you remove the old cover, seat the new one fully and run a rinse to check it drains cleanly.
