Have you found a solution to this problem? I have this very some problem but I can not put my finger on the exact time it started? I called KitchenAid service and the service man told me that the wash water was not hot enough and said to always run the washer with "HighTemp Wash" turned on. This did not make the difference.
So, where are you on this?
: I installed a new KitchenAid dishwasher without an air gap. Also, I have a single basin, farmhouse sink with a new garbage disposal. We have installed all new plumbing in the kitchen. The dishwasher doesn't work. We are now on our second dishwasher and it has the same problem - the dishes are murky, there is white residue on everything and food particles throughout the dishwasher. It appears that the dishwasher isn't draining before it starts the next cycle. Could the lack of airgap be the problem? We looped the hose as high as possible as recommended. My mother has the same dishwasher and it works great. We feel there is something wrong with our plumbing but not sure what.
