Dishwasher doesn't wash no pressure or spray

Dishwasher Repair

I really need some help here, there is no water being sprayed from any of the sprayers, the dishes don’t get wet. Could it be the impeller? I tested the dishwasher by putting glasses in the four corners on the top and bottom rack, there was no water in any of them. I cleaned the accumlator assembly and anything else I could see. The dishwasher fills and drains fine, it just doesn’t wash the dishes. I opened the washer and took a quick look, the water is barely making it out of the bottom sprayer. I obviously need a new part, just don’t know which one.
