Robert P Cincinnati , OH December 09, 2016 Upper spray kept falling off when using dishwasher I was unable to remove the screwed snap outlet, therefore only replaced the upper spray arm and the wash arm retaining clip. This fixed the problem. It would have been helpful if a tip were given as how to remove the screwed in outlet snap nut. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
