I removed the screws on the dishwasher door using a T-15 torx screwdriver. I then separated the outer and inner door. I then removed the 5 3/16 screws holding the lower door gasket seal. I replaced the old gasket seal with a new one that I purchased from AppliancePartsPros.com. I then reattached the inner and outer doors. I made sure that the dishwasher unit was level afterwards.
