Chris J Hyde Park , NY November 07, 2023 Appliance: Whirlpool Dishwasher WDTA50SAHV0 Whirlpool Dishwasher Wdta50sahv0: Leaking from bottom of dishwasher door. How to replace Lower Door Seal. Replaced inside rubber door seal and door bottom seal. The bad seal was only slightly damaged but enough to leak. Looking at the slight damage I would never have guessed it would cause the leak. The bottom door seal was a pain in the neck. Getting the screw holes lined up was tedious even with taping seal in place. My suggestion is to use a self tapping screw from bottom seal removed earlier and to start the screw in the seal to 'tap' the plastic. Do not screw all the way in just start it so that when seal is taped on place the screw will 'bite' easier when installing the bottom door seal . This will save lots of frustration.
