I've checked many of the forum topics on this, and I think this might be different..
My dishwasher is a Whirlpool Quiet Partner IV and has worked perfectly for 2-3 years in my old house. We moved it to the new house and I installed it. The supply plumbing and wiring was simple, but in the old house we had the drain hose installed over the disposer (although not correctly) and the dishwasher still worked correctly. In this new house, the drain hose goes from dishwasher to high loop to basement where it meets a dedicated p-trap. My question is -- is all of that necessary? The dishwasher doesn't drain correctly and I wonder if all these backflow preventions are causing drain problems. My other option would be to run the 8 feet of hose around to the disposer. I'm thinking the trap prevents gasses, but does it prevent sewage backflow per requirements? I've also heard rumors some newer dishwashers have internal hose loops? Many questions.. help, please and thank you.
