Probably the drain hose from the dishwasher isn't high enough to keep the water from running back . The hose should be above the level of the disposal at some point.

Some states require an "air gap" which is a device that is placed in the drain line to prevent this. Some states require a simple high loop in the drain hose. Many dishwasher manufacturers are now installing backflow preventers in the dishwasher.

If you do not have a disposal or are removing it, there is a extension tube for the drain that has the dishwasher tube in it. The disposal does not have to work for the dishwasher to drain. The water is run through the disposal so that any food particles get ground before going in the drain. After a while, the disposal will begin to smell if it is not run.
