Remove the lower dish tray and set aside. Remove two Phillips screws on each side of inner liner, then close door. You should then be able to slip off the external facing (set aside). Pull lower gasket toward tub until fully removed. Reinsert the new gasket into the same tight slot, making sure that the notch inserts into the slot and the flexible gasket runs the full length of the tub. The gasket should bow out slightly toward the tub. Also make sure that the side seals do not interfere with the bottom seal fully mating with the floor of the tub. Close the door and check to make sure the lower gasket reveal is the same across the length of the inner liner. Reinstall the dish tray, then reinstall the external facing, using the same four Phillips screws to secure. Test sealing by running a short cycle on the dishwasher.

Still have a slight leak, but I'm thinking it may just need time to seat itself.

watched a video, really easy fix. Solved the problem!
