My kenmore diswasher is not getting water to wash dishes tried lifting and unlifting the valve still not working but I can hear the motor running,plus my dishes has a lot of white thing all over the dishes

Either the water supply to the DW is blocked, the water solenoid is blocked or defective. It could be the level switch too, but I would go with supply first.

So if you start a cycle you can hear the motor running but if you suddenly open the door they are still bone dry, right?
