How to Replace a Maytag Dishwasher Door Gasket

The perimeter gasket compresses when the door closes to make the watertight barrier, and over the years it hardens, cracks, or takes a permanent set until it stops sealing. Maytag's higher-pressure heavy cycles can expose a weak gasket that a gentle cycle would not. Water running down the door sides points to the perimeter gasket, while water pooling at the very front points to the bottom seal.

Before you start#

Safety warning: No electrical disconnection required for gasket replacement. The gasket is accessible with the door open and no panels removed. However, if you are also replacing the bottom door seal that sits under the door, turning off the breaker is prudent to prevent accidental cycle starts while your hands are near the mechanism.

Step-by-step#

1 - Confirm which seal leaks. Water down the door sides is the perimeter gasket; water on the floor right in front is the bottom seal. Both are cheap and easy, so replace both together if one is clearly worn.

2 - Pull the old perimeter gasket. Starting at the top center, grip the gasket and draw it out of the channel that rings the tub opening; it is held only by its hooked lip, with no screws. Work down both sides and finish at the bottom, using the flat-head to coax stubborn sections without scratching the tub.

3 - Clean the channel. Scrub away mildew, scale, and old debris with warm soapy water and dry the channel fully, since a damp or dirty channel keeps the new gasket from seating. Inspect the channel for dents or corrosion in the bottom corners where water collects.

4 - Relax and lubricate the new gasket. Straighten the new gasket on a flat surface or warm it briefly so it is pliable, then wipe a thin film of glycerin or silicone lubricant on the lip that inserts into the channel. Skip petroleum lubricants, which degrade rubber.

5 - Seat the perimeter gasket. Press the lip into the channel at the top center and work outward to both sides at once, thumbing it firmly every few inches. At the corners, press the gasket in without stretching it so material stays available for the straight runs, and finish at the bottom center with no gap or overlap where the ends meet.

6 - Replace the bottom door seal if needed. Slide the old bottom seal out of its track along the door's lower edge and slide the new one in, hanging with its lip angled toward the tub and free of twists.

7 - Test the seal. Close the door, which should shut with slight resistance from the fresh gasket. Run a short rinse and check the whole perimeter and bottom for moisture. A paper strip held between gasket and tub should resist pulling at every point.

8 - Let it break in. A new gasket is stiff and may seep slightly at the corners for the first few cycles as it conforms to the tub, reaching a full seal within about a week.

When to call a professional#

EasyBear technicians serving Sacramento and the Bay Area carry Maytag-specific diagnostic tools and replacement parts on every service call.

• The tub edge is visibly warped or dented and blocks proper seal contact.
• The leak comes from below the tub rather than the door edge, pointing to a hose or pump-seal fault.
• The door will not close parallel to the tub, indicating a latch or alignment issue.
