This replacement pump filter, also known as a filter assembly, is a genuine OEM part for your washer or washer/dryer combo. Before beginning this repair, turn off the power and water supply to your washer. The filter assembly may need to be replaced because it is broken or is leaking water. To locate the filter assembly, pry open the small door on the front of the washer, using a flat-blade screwdriver. Unplug the drain hose next to the filter and drain the water into a bucket. Then unscrew the pump filter, and replace with your new one.
