I looked up the parts schematic for my KitchenAid dishwasher on the website, then watched the helpful video on how the parts go together. That let me know exactly what parts and tools I needed, so I ordered the parts and installed them. The only difference I noted was the fact that my machine was slightly different: The spring on mine mounts in the center of the handle instead of on the side. Very easy installation, though, and now it works like new.
