Front-loading washing machines have built-in rubber seals that prevent water and soap suds from leaking out through the seams between the door and machine opening. Over time, a seal can become cracked, warped, or develop leaks. Replacing the door seal yourself can prevent further leakage from a bad seal.
Unplug the washing machine's power cord from the wall outlet. Turn off the water supply, either the main house supply or the individual valves on the water-supply lines running into the back of the machine.
Open the machine's door. Inspect the edges of the machine opening where the door-seal rubber meets the metal of the opening.
Locate the outer clamp band that keeps the door seal in place. Place the tip of the flathead screwdriver under the outer clamp band and gently pry it up off of the seal. If the band is stuck, inspect the area for plastic clamps holding it in place. Remove the clamps and finish removing the band and door seal.
Rub a small amount of liquid fabric softener on a rag and apply to the groove on the machine opening where the previous seal was located. This helps the new door seal slide into place.
Position the new door seal and work it around the machine opening. The seal goes into the groove and slightly overlaps onto the outer metal of the machine opening.
Locate the clamp adjustment on the band and tighten it until the band's circumference matches the machine opening's circumference. Start from the bottom, pushing the band into the groove on top of the door seal, working around the edge until the band clamp is fully in place. Replace any plastic clamps removed earlier.
Turn the water supply back on and plug the washing machine back into the wall outlet.
