Wheel axle broke off and top rack was flopping

Screwdriver to release the 2 components that wraped the rack. removed broken part and reinstalled the new part. I expect that I will be buying more parts from Part Select because the Kitchen Aid dishwasher is a piece of crap. we paid $800 for an appliance that I hate. 2 years old and the top rack breaks, the cycle buttons are crap. poorly designed appliance! Part Select saved the day. I first went to Kitchen Aid web site and the model didn't exist! Stay away from KItchen Aid!
