I ordered replacement roller tracks which arrived quickly; original equipment in original packaging. I studied the YouTube videos which were detailed and helpful. The only hard part of the repair was rolling the dishwasher out from the cabinetry to gain access to the sides. My dishwasher was screwed to the cabinet sides, not the top as shown in the video. In my case, the water supply line was soft copper and had to be disconnected. Problem was that my shutoff valve would not shut off so I had to bring in a plumber to replace it. The plumber also gave me a flexible stainless steel water line to replace the copper which means I can roll the DW out more easily next time without disconnecting anything (my electrical and drain connections have enough slack). Actually replacing the roller tracks was simple.
