Dishes were not cleaning.

One of the upper rack wheels mounting pegs broke off and fell into the chopper assembly which broke it. It took about 1 hour to figure out how the dishwasher comes apart. The assembly is under the protector cover assembly. To get to this you need a TORX screwdriver. The feed tube assembly is held on by two clips. Rotate it clockwise to free if from the accumulator assembly. Four screws remove this cover and one more screw takes off the protector cover. You remove this cover by lifting it straight up. The whole assembly needed to be cleaned from food particles. It was difficult inserting the new chopper assembly. After a few tries , it finally fit. Putting it back together took only 30 minutes. Cleaning took more than 2 hours.
