Fold the seal in half to find its midpoint.
With the correct side of the seal facing out, press the seal's midpoint into the center point of the channel on the top of the dishwasher.
Press the seal into the channel across the rest of the top and evenly down both sides of the door, without stretching the gasket. Press the seal as far into the channel as possible without stretching the seal. An inch or two of seal extend beyond the bottom of the channel on each side to help seal the bottom of the door opening.
Shut the dishwasher door to firmly push the gasket into the channel. Open the door and check the alignment and seating of the gasket. If necessary, remove and reinstall the gasket to ensure a good fit and seal.
Leave the door shut for several hours to permanently set the gasket and help it seal properly
Tip: It's normal for the dishwasher door to be a little more difficult to close and latch for several days after you install the new door seal.
