Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Visible tear, crack, deformation, or loss of tension in the rubber boot
• Water pooling or dripping at the lower front of the door
• Persistent mold or mildew embedded in the gasket that does not clean away
• Musty odor originating from the door-seal area
• Boot edge pulled out of its retaining groove or visibly loose

Check Before Replacing

• With the washer unplugged, visually inspect the entire boot for tears, cracks, pinholes, deformation, or sections pulled out of the retaining groove.
• Wipe the gasket dry and check the lower fold and drain openings for trapped debris or water.
• Run a brief supervised rinse or wash cycle only if safe to do so, and observe whether water emerges specifically from the door-seal area rather than from a hose, dispenser, or bottom-panel leak.
• Confirm that the washer door closes evenly and that no clothing or foreign object is trapped between the glass and gasket.
• Do not remove the boot or retaining clamps unless following the appliance service documentation for the exact washer model.
