We have had this dishwasher a little over a year now. We made a service call on this unit because it started making an awful noise while it was still on warranty. I would open the door when it was doing this and there was no water in the unit. It appeared to clean the dishes, and contained a lot of steam. Closing the door again, this noise would continue.
Service cleaned the food chopper and it seemed to be ok for a bit. But the noise continued. Another service call and another look at the device. They had no idea what was causing it.
By now, its off warranty. And of course KitchenAid will not cover labour even though they never solved the problem. I will never buy KitchenAid again.
So, finding articles on this forum and elsewhere. I removed and inspected the food chopper. It was clean. I reinstalled the same chopper. And it sounded fine. Now 10 washes later and the noise returns.
So, do I replace the chopper? Or is there something else going on?
It seems to make this noise near the end of the wash.
