I had this problem. Here is the solution. You'll need a compressed air source, even a small compressor.Remove the hose from the pvc trap pipe under the sink. (one screw) Using a blow gun, force air back through the hose until water gurgles up in the dishwasher. Then watch the water drain.! Works every time. Hose needs to be bigger, bad design. Technician will charge you big bucks for same procedure. Good luck.
