Shut the water off under the cabinet. Remove the handle and the #3 cap assembly STOP!! don't remove any more. Pull straight up on the spout #4 and see the diverter #10 in the front of the valve body. Clean everything inside and out. Make sure the "O" ring on the diverter. If you have any doubts take the diverter in to a Delta dealer and replace it. Good luck, Tom
