There is probably a little "float valve" in the bottom of the dishwasher that is stuck. It might look like a little dome shape or small plastic can-shaped object in the bottom of the dishwasher. This valve floats as water comes into the dishwasher. As the water rises to the correct level as it's being filled, the valve floats and it turns the water off when it's up. It might be stuck in the Up position and thus it's not allowing water to come in.
