This drain hose plug, also known as a hose cap, is a genuine OEM part for your washing machine. This plug caps the drain hose from the pump housing, and helps prevent leaks from your washer. Before beginning this repair, make sure the power and water sources to your washer are shut off. To access the pump housing, open the pump filter cover, pull out the drain hose, remove the old plug and replace it, first draining the remaining water from the drain hose.
