Elizabeth D Afton , VA May 19, 2015 Leaking hose upper spray arm and drain hose replacement Removed dishwasher to replace spray arm pine--I replaced washer on pipe, too, and would recommend doing this just on principal. Removing dishwasher requires disconnecting power, water, and drain line--tools will vary depending on connections. i replaced drain line because original install was not done correctly--hose too short--You could probably do just this w/o pulling unit. All parts arrived very quickly and fit correctly. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
