Washer Door seal (boot): What It Does and Signs It's Failing

On a front-load washer, the door seal (or boot) is the thick rubber ring between the door opening and the tub. It keeps water in while the drum spins and flexes as the tub moves inside the cabinet. A spring clamp holds it to the cabinet front and another holds it to the tub.

How it works

The rubber folds flex every time the tub rocks in the spin, and over years the rubber cracks or tears, faster in a washer that's often overloaded. A tear or a loose clamp lets water run down the front of the machine.

Signs it is failing

• Water on the floor at the front of the washer
• Holes, cracks or tears in the folds
• A musty smell from the door area that keeps coming back
• Clothes catching in the rim

Water under the door often comes from this part. Overloading the drum wears boots out faster.

Can you replace it yourself?

Leave the door ajar between loads so the boot and tub dry out, which keeps mildew down. To replace it, unplug the washer, take off the outer clamp ring, peel the boot off the cabinet and work the inner clamp off the tub. The outer spring is tough to stretch alone, so a clamp tool or a second person makes it a lot easier.

Buying the right part

Some boots are sold without clamps, and on some LG models one version has a drain port and another doesn't. Compare the part number on the old boot before you install the new one.
