[COLOR="Blue"]we can hear the water circulating, however it is not coming in to the unit.[/COLOR]
I am not sure what you mean by the above re: if there is no water in the unit I do not understand how you can hear it circulating?

If you open the door after the unit does a fill cycle is there water in the bottom of the tub?
There should be most units fill to just under the heating element.

Can you hear the water entering the tub?

Has the unit ever run OK for you?

Is there a separate water shut off on the water supply line?
If there is, is it open?
Perhaps the former owners shut it off as a safety measure.

If you loosen the supply line at the water valve does it start to drip?
If yes.
Then re-tighten the fitting and get a meter and check across the valve when it should be filling.
If there is 120 volts and there is no water flow into the dishwasher you may have a bad replacement valve.
