How to Replace the Chopper Assembly in Your KitchenAid Dishwasher

  1. Open your dishwasher door and take out your appliance’s lower dish rack.
  2. Disengage the locking tab on the water supply tube while rotating the bottom half of the tube clockwise. Then, pull out the lower spray arm and the bottom of the water supply tube.
  3. Using a Phillips screwdriver unthread the screws securing the lower wash arm support assembly and its filter, and then lift the assembly up and out of your dishwasher.
  4. On the sump assembly, unthread the screw that secures the foreign object protector to the assembly. Next, lift the protector up and out of your appliance.
  5. Now take out the screw that holds down the pump inlet protector, and then take the protector off the sump assembly.
  6. Under the pump inlet protector, you’ll find the chopper assembly. To remove the chopper, insert a flat-head screwdriver behind the chopper blade and push the blade forward to release the assembly’s central pin. Next, pull the chopper assembly off its shaft.
  7. Take your new chopper assembly out of the box and start the installation process by placing the more narrow side of the chopper screen into sump pump housing first. Next, insert the chopper assembly onto the motor shaft. To lock the chopper in place, use a screwdriver to rotate the part’s central pin.
  8. Now it’s time to put your dishwasher back together. To start, reinstall the pump inlet protector and the foreign object protector.
  9. Next, replace the lower spray arm support assembly and secure it with the screws you took out earlier, and then reinsert the lower spray arm and the bottom half of the water supply tube.
  10. To finish up, reinsert the lower dish rack and close your dishwasher door.
