Front-loading washers have a seal on the door that prevents water from leaking out the front of the machine. After years of mineral deposits collecting on the seal as well as opening and closing the door, the seal may break down. Small holes and cracks will appear in the seal which lets water leak through. Replacing the seal does not require a professional repairman. Order spare parts from the manufacturer of your machine to ensure a good fit.
Open the door of the washing machine.
Pry off the metal clamp band from around the seal of the machine, using a flathead screwdriver.
Pull the seal away from the door.
Clean out the groover for the seal using a clean rag.
Rub petroleum jelly into the groove for the seal. Push the new seal into the groove.
Push the clamp into place.
