Water leaking from Inlet Valve
Remove the bottom cover plate. Disconnect the water inlet and black rubber hose. Remove 2 mounting screws. Pull out electrical connector. Reverse order. Be sure to get the brass inlet connector really tight so it won't leak. I did the final tightning after the part is mounted. Not a bad repair at all. The only problem was that it leaked in the first place and messed up my subfloor and laminate flooring.

Bottom Door Seal fell apart and started leaking.
First I opened the door all the way. Second I reached down to the bottom gasket then grabed it on the right end of the seal that is on the right side of the door. Then I pulled the end outward from the bottom of the door toward the heater coil in the bottom of the washer. It came out real easy. You see it just snaps into a little plastic groove under the door. I then cleaned up the area for food and soap particules. I then placed the new gasket in place by lining up the notch toward the right end with the piece of plastic that encloses the right end of the plastic notch on the bottom right end of the door. Then push it in untill it stops going into the notch. It snaps in but does not make a snaping sound. It just won't go in no more.
