Do-It-Yourself Stories from Customers like You Leaking hose upper spray arm and drain hose replacement   Elizabeth D. • Afton , VA • May 19, 2015

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. Read more
