The wheels on our KitchenAid dishwasher keep falling off because the retainer clips have degraded over time. There are several versions of this part across other sites, but I couldn't find one I liked so I modeled my own. It went through several iterations to ensure a good snug fit and function. Enjoy the satisfying “click” when it's fully installed!
If you like this design or if I've saved you some time, please consider giving this model a Boost!
