TOP SPIN ARM NOT SPINNING TO CLEAN TOP RACK OF MY KITCHEN AID DISHWASHER. IT IS ONLY 1 1/2 YEARS OLD AND MY TOP TACK IS SUDDENLY NOT CLEANING

Check the arm for plugged holes Make sure the screen at the bottom of the dishwasher is clean. Take it out and look to be sure.

Hi,

On your model, upper rack cleaning issues are most often linked to debris in the inlet to the pump. I have put some instructions together on cleaning this. If you follow the link it will explain how to check and clean this.

Possible that the motor impeller has good particles in it, causing poor water pressure, which would be most evident on the top rack. You would have to remove the spray arm, then the filter, then the torx screws to get at impeller....unfortunately, that model of dishwasher isn't the greatest in the first place for washing, since it only has the one spray arm.

the spinning of the arms is created by the force of the water shooting out of the holes. your top arm may have debris build up in it that prevents proper water flow. u can also remove the arm and see it there is build up on the contact point were it rotates. clean it if its dirty. "dishwasher magic" is good for cleaning mineral build up in your system. also, make sure your not putting dishes on the top rack that are too tall and prevent the blade from rotating

replace the top spray arm and it should work ok again

Sounds like you have 1 of 2 problems. Either your pump is clogged or you need a bigger drain loop.

You'll need to clean the food chopper in the base. Make sure you've got a torx screwdriver.
