Stephen M Carmel , CA June 17, 2020 Poor cleaning especially the top rack / glasses Restored pressure to the top rack spray arm by replacing the water supply tube. The tube in my model has two valves, one of them is supposed to be closed while the other is open and supplying water to the top rack spray arm. This fixed my washer and now it's working fine. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
