How to Replace a Front-Load Washer Door Boot
Why this matters
The door boot (also called the bellows or door seal) is the rubber sleeve that joins the stationary front of the cabinet to the tub, which moves on its springs and dampers every time the drum turns. It is the most common source of a front-loader leak at the door, and replacing it is a routine job that turns into a callback for one of three reasons: a clamp seated on rubber instead of over the lip, a boot rotated a few degrees so its drain holes sit high, or a spray or vent fitting left on the old boot. This card runs the job in the order it happens, with one real replacement carried alongside each step so the reason for the step shows up in the numbers.
The job used throughout. A front-load washer leaking a cupful onto the floor at the front during spin. With the door open and the boot folded back, a split about 2 in long runs through the bottom fold at the 6 o'clock position, with a coin lodged in the fold beside it. The maker's replacement boot has an alignment mark molded into the outer lip and two drain holes at the bottom of the inner fold.

The outer lip hooks over a flange on the cabinet front panel and the outer clamp ring holds it there. The inner lip hooks over a lip on the tub front and the inner clamp holds that. Between them, the fold lets the tub move. The drain holes at the bottom of the fold let water that collects there run back into the tub; rotate the boot and those holes sit up the side, the fold fills, and it overflows forward past the outer lip.
Before you start
Power and water. Unplug the washer and close both supply valves. There is no resistance reading in this job, but your hands will be inside the drum and at the door lock harness, and a washer plugged in can start a cycle from a bumped control. Drain the tub through the drain pump filter or emergency hose into a shallow pan before you touch the boot; water held in the tub pours out of the inner lip when its clamp comes off.
Spring clamps. The outer ring, and on many models the inner one, is a heavy spring wire under tension. Wear eye protection whenever you stretch or pry one. A spring that slips off a screwdriver flies, and it flies toward the face of whoever is crouched at the door.
Mold. An old boot that has held standing water often carries black mold in the fold. Wear nitrile gloves, and an N95 filtering facepiece when the growth is heavy, since flexing and folding the boot sheds spores into the air at face height; voluntary use falls under 29 CFR 1910.134 Appendix D. Bag the old boot in the drum before you lift it out.
Sharp edges. The cabinet flange and the tub lip are pressed steel and plastic with burrs. Gloves on for the whole job.
The job, step by step
1. Remove the outer clamp ring. Find the spring's hook or the band's screw, usually at the bottom or top. On a spring wire, slip a flat screwdriver under the spring next to the hook and lever it out from the flange a little at a time until it comes off, working around the circumference. On a band, back the screw out. Why: every other step depends on freeing the outer lip. Prying the rubber off with the clamp still on tears it, which does not matter on the old boot but marks the flange. On this job: a spring wire, hook at 6 o'clock. It comes off with the screwdriver in two places.
2. Peel the outer lip off the cabinet flange and fold the boot into the drum. On many models this is enough to reach the inner clamp through the door opening. On others the front panel or the top panel must come off first, and the door lock assembly may need to be unscrewed from the panel and left hanging on its harness; the tech sheet says which. Take a photo of the boot's position, including where the alignment mark and the drain holes sit, before going further. Why: the photo is the reference you check the new boot against, and it costs nothing. On this job: the inner clamp is reachable through the opening with the front panel in place. The photo shows the old boot's mark at 12 o'clock and its drain holes at 6.
3. Remove the inner clamp. A band clamp loosens with its screw, usually reached at the top. A spring inner clamp levers off like the outer one, and here it is harder to reach, so take your time with eye protection on. Why: this is the clamp that seals water. Its removal is also where the seating of the new one is decided, so look at how the old one sat: band centered in the boot's clamp groove, over the tub lip, all the way round. On this job: a band clamp, screw at 12 o'clock.
4. Remove the old boot and transfer fittings. Work the inner lip off the tub lip all the way around. Before it goes in the bag, check it for anything the new boot needs: a spray nozzle or recirculation hose connection on some models, a vent hose port, a door ground wire. Disconnect hoses from the old boot, noting which port each came off. Some new boots come with these fittings already molded in; others need the old nozzle moved over. Why: a recirculation nozzle left off sprays water onto the cabinet instead of into the drum, which looks exactly like a new leak. On this job: one recirculation hose to a nozzle molded into the boot at 12 o'clock. The new boot has the nozzle molded in; the hose transfers.
5. Clean the tub lip and the cabinet flange. Wipe both clean of detergent scale and mold, and look for a nick or crack in the tub lip. Why: scale left on the lip holds the rubber off the surface, and a crack in the tub lip leaks however well the boot is seated, which means a tub or tub-front repair, not a boot. On this job: scale wiped off; no damage to the lip.
6. Seat the new boot's inner lip on the tub lip with the mark at top. Line up the alignment mark at 12 o'clock as the maker shows (usually a triangle or arrow), which puts the drain holes at 6. Start at the top and work the lip onto the tub lip in both directions with your fingers, ending at the bottom. Some makers suggest a little soapy water on the lip to help it slide; follow the instructions in the box, and never use oil or a petroleum-based lubricant, which swells some rubbers, and skip silicone spray, which leaves the lip too slick to hold under the clamp. Why: the mark sets the drain holes. A boot seated a quarter turn off works for a week, then the fold fills and overflows. On this job: mark at 12, holes at 6, lip seated all the way round by running a finger along the joint to feel that there is no gap.
7. Fit the inner clamp in its groove. Set the band or spring into the clamp groove molded in the boot, centered over the tub lip. On a band, tighten the screw to the maker's torque if one is given; overtightening a band can crack a plastic tub lip. On a spring, a second pair of hands or a clamp tool helps. Why: a clamp sitting on the rubber beside the groove instead of in it squeezes nothing against the lip, and that is the single most common cause of a leak from a new boot. On this job: the band is tightened, then the boot inspected all round. At 4 o'clock the band had ridden up onto the rubber outside the groove. It was loosened, pushed back into the groove, and retightened. Missed, that spot would have leaked on the first fill.
8. Reconnect fittings and the outer lip. Push hoses back onto their ports and refit their clamps. If the front panel came off, it goes back on now, along with the door lock assembly and its harness, since the outer lip seats on its flange. Then fit the outer lip over the cabinet flange, starting at the top. Why: doing hoses before the outer lip keeps your access open. On this job: recirculation hose back on its clamp at 12 o'clock.
9. Fit the outer clamp ring. Start the spring hook at its position, hold it with one hand or a helper, and work the spring around the groove of the outer lip, stretching it into place over the last few inches with a screwdriver or a clamp tool, eye protection on. A band, if that is what you have, tightens with its screw. Why: this clamp keeps the outer lip on the cabinet. Loose, the boot can pull off during a spin. On this job: spring on, groove checked all round.
The finish test
- Close the door and check the lock. A boot fitted proud of the cabinet can hold the door off its strike, and the washer then refuses to lock. The door should close with normal force and latch.
- Restore water, check every hose you disturbed, restore power.
- Run a full cycle with a small load, not just a rinse. The fill, the tumble, and especially the spin each load the boot differently, and a leak that waits for spin will not show on a fill.
- Watch the bottom of the door during the fill and tumble, from beside the machine, and look under the front edge of the cabinet with a flashlight at the end. Dry paper towel laid under the front edge before the cycle makes a small drip obvious.
- After the cycle, open the door and look in the fold. A little water in the fold that drains away through the holes is normal. A fold holding a puddle means the drain holes are not at the bottom.
On this job: door latched and locked; full cycle with paper towel under the front edge; towel dry at the end; the fold held a few drops that drained away.
Write on the ticket: what was found in the old boot (tear location and cause), fittings transferred, the clamp reseat at 4 o'clock, and that a full cycle ran with no drip. Tell the customer what the coin did, and to leave the door ajar after a wash so the fold dries, which slows mold.
If it still drips
The order to check, from most to least likely: the inner clamp not in its groove somewhere, a hose fitting on the boot not clamped, the boot rotated so the drain holes are not at the bottom, a nick in the tub lip under the inner lip, and suds escaping on an overdosed load (too much detergent, or a non-HE detergent, foams past the door on any boot). The last is not a boot fault, and the customer conversation is about the detergent.
