Do you have an upward loop in your drain line under the sink? Dishwashers require what's called an air gap in the drain line to work properly. If you have the manual for the dishwasher there will be a section in it describing this.

If you have the loop, is the dishwasher computer contralled or an old rotary dial control? Some have sensors that tell the control panel when no water is left and others go by an expected time it should take to evacuate the water. A sensor could be defective or something is wrong with the timing. Can you hear the pump running without water being pumped out? The likely culprit is the drain line obstructed or without an air gap as described above but there could be other problems that need to be diagnosed with deductive reasoning.
