Deborah D Eldersburg , MD June 12, 2017 Appliance: Model KITCHENAIDE Dishwasher not cleaning properly First time I took it apart and cleaned out the filter and debris under the screen. Still didn't clean properly so I realized I needed to look at the chopper assembly. That was mangled and not even attached to the motor shaft. Watched several youtube videos that gave me enough info to proceed. I did need to buy a special star shaped socket set. Needed t15 and t20 I believe. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
