Check and see if the water line going from the dishwasher to the disposal has enough slack to run up and over the connection to the disposal.If its just running along the cabinet floor and straight up into the disposal that's the problem.Its called an anti siphon loop

Can you run the dishwasher if the garbage disposal is not connected?

The disposal has to be in place so that the drain on the dishwasher is connected. 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.
