The sink drain is plugged,or you have the dishwasher hose hooked up in wrong place.
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.
replace the connector
You would have to put a casing around it, find a different incoming water hose, and adapt the drain hose.
If if won't pump all water out, the d/w hose or sink drain is plugged.
If the dishwasher is hooked into a garburetor, there is a plug in the garburetor where the hose drain attaches that needs to be knocked out. The drain hose might be plugged where it joins to the plumbing drainage. The other problem, plumbing-wise, is the drain hose has to be fed as high as it can go under the sink and back down into the drain.
Shut the electrical breaker off and lock it out. Undo the drain hose under your sink. Shut off the water supply under the sink to your dishwasher.Take the bottom front panel off the dishwasher. Undo the water supply attachment to your dishwasher. Open the door to your dishwasher and take out the screws attaching the dishwasher to the counter. Undo the electrical connection to the dishwasher. Slide the dishwasher out. You may have to adjust the legs to get the dishwasher out. If you have a new dishwasher to install, read the directions for installing it, do the reverse to take the old one out.
Fit a short length of capped hose to the disoposal fixture.
