Is the washer leaking at the hose connections? Are the gaskets missing from the hoses?
Check to see if the washer is leaking where the inlet hoses are connected to the washer and to the faucet. Make sure both ends of both inlet hoses contain the hose washers that came in the parts bag with the washer. Make sure all the connections are tight. If necessary, tighten the connections to avoid leaks. See the Installation Instructions for details; enter your model number in the search tool below to find them.
