My Whirlpool dishwashers upper track broke and I searched everywhere for this part, even on Whirlpool.com and could not locate the correct part needed. I fell upon PartSelect in my searches, and there it was! It was exactly what was needed, easy instructions and install. My dishwasher was fixed quicker than I could find the part. I'd recommend this site for genuine appliance parts need for your home. Parts were not plastic, which was why the others one broke so quickly, and work as though it was never broken. Don't hesitate to use this site.
