Kitchenaid dishwasher sucking noise when ON

Question

Hello,

Our built-in KitchenAid diswasher stopped working. Whenever the ON/OFF switch is ON, it makes a sucking noise. 

Before this all started, whenever we selected a cycle, ppressedON and closed the door, a cleaning cycle would begin. Now, when we push the cycle button and press ON, all it makes is a sucking noise (for as long as the ON button is on) and cycles do not start (it does not clean).

Any solutions?

Thanks
