Jeff D Aurora , CO July 15, 2017 Sagging upper tray in dishwaser I went online to see the schematic on this particular Whirlpool dishwasher. After assessing the problem I was able to order the required parts easily online. They were delivered in three business days and I installed them in less than thirty minute. The new parts totally eliminated the hassle fighting with a sagging shelf. Very pleasant experience. 17 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
