Heather D O'fallon , MO March 04, 2016 The tube that the water goes through to the sprayer arm on the underneath side of the top rack fell off and melted against the heating coil I purchased the kit that replaced the sprayer arm, water tube, and the plastick hook that holds the tube to the rack. Once those three pieces were in place the dishwasher was back operating as desired. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
