Understanding the Problem
The door boot (also called the bellows or gasket) seals the front of a front-load washer door to prevent leaks and keep laundry inside the drum. Over time the boot can tear, become permanently deformed, or develop mold and hard-to-remove residue that prevents a watertight seal. When that happens you may notice water leaking during fill, wash or spin cycles or a persistent mildew smell. Replacing the boot is a common repair and is typically done by removing the door retaining band or outer clamp, taking out the old boot, cleaning the mounting surfaces, fitting the new boot into the lip on the tub and door, then securing it with the clamp. Always disconnect power and water before starting and verify the replacement part number matches your model — small variations in boot shape exist between models and revisions.
Common Symptoms
Visible tears, cracks or holes in the bellows; water leaking from the front lower area of the washer during fill/wash/spin cycles; strong mildew or musty odor coming from the door area.
Common Causes
- Normal wear and age causing rubber to crack or become brittle
- Sharp objects (coins, zippers, bra wires) trapped between drum and boot
- Chemical damage from bleach or harsh detergents or repeated high-heat cycles
- Improper loading or frequent overloading stressing the boot material

Helpful Repair Tip
Confirm the boot is the problem by visually inspecting for tears, soft spots, or separated seal. Run a short cycle with the machine empty after partially pressing the boot inward; watch for moisture or leaks around the lower front seam to pinpoint the leak area.
Frequently Asked Questions
Can I replace the door boot myself or should I call a technician?
Yes — many homeowners can replace the door boot themselves if they are comfortable with basic appliance work. Required skills: disconnecting power and water, using simple hand tools (screwdriver, pliers), removing the door clamp, and reseating the new bellows. Allow 45–90 minutes. If the boot is glued, if the inner tub clamps are corroded, or if you’re unsure about matching the correct boot part, call a technician.
How do I prevent the new boot from failing or developing a moldy smell?
Prevent problems by removing sharp objects from pockets, using mesh bags for small items, avoiding overloading, and using the correct detergent and amounts. After washes, leave the door slightly ajar to air out the drum and boot. Periodically clean the gasket with a mild detergent and water or a vinegar solution, and wipe dry to prevent mold build-up.
