I replaced the door gasket, then the lower seal but it still leaked. The leaks were located near the hinges. Finally, I called Sears repair to come and check it out. The repairman was nice but had to consult Whirlpool. Whirlpool told him to immobilize the spray arm 12 to 6 and run the DW. No leaks, so it was the lower spray arm. I ordered the part and replaced it as soon as it arrived. Thanks, no more leaks.
