leaking alittle water behind drain valve solenoid

I removed 2 lower front axcess panels,removed "e" clip on plastic cam on drain solenoid with a small pick,removed 2 springs with needle nose pliers,remove 2 mounting screws holding solenoid to drainvalve. remove push on nut on drainvalve shaft with a set of side cutters I bent it in half and cut it off then used the pick again to remove the seal. i soaked the new seal in warm water with a little dih soap so it was more flexible when sliding it into the seal seal , then with a deep well socket just big enough to go around the drain valve shaft i pressed the push on nut into place. i then revirsed the steps to reinstall valve sloenoid screws,cam & springs ran the dishwasher to check for leaks and then reinstalled the lower covers. total time took about 30 min ps have a magnet around for when you drop the "e" clip (and you will) trying to reinstall it! good luck.
