For JUDYII.
Well it goes like this, your drain hose in connected to your disposal and that I found was the problem with what I have, So what I have done to correct this issue; Is I removed it from the disposal and re connected above the p-trap. if you can see the elevation for the drain is to high attached to the unit. And while you us your disposal, what ever you are disposing it go back into your drain hose that causes a blockage. And after doing so try your dishwasher again, rest to sure the problem is gone. remember to plug the disposal drain for the D/W .so try doing this your self and stop paying the high dollars when the problem as been justified. see ya.
