After making a selection on the control panel and closing the door, it sounds like the dishwasher is circulating water (to reach the desired temperature) and then starts to wash (although it sounds louder and kind of grinding). The problem is that when I open the door, there is no water in the unit. A while back, my wife tried to do a load of dishes without realizing that the hot water supply was turned off. I don’t know if this could have damaged something and led to the problem.
Here are your parts as yo can seeyou seem to be missing several digits at the end of the model number.

Check that the float switch is being activated (closed)
Sometimes the float can get stuck in the up position. If it is then usually cleaning it will fix the problem.
If the overfill switch is being activated, check for 120 volts across the fill valve when it should be on.
If there is no voltage, check across the fill valve/overfill switch combo.
If there is no voltage there, then the control board is probably toast.
If there is voltage, then check across the overfill switch. If there is voltage across the switch then the switch is shot.
If there is 120 volts across the fill valve then either the fill valve needs replacing or it’s filter needs cleaning.
There is a screen filter built into the input side of the valve. Remove the valve from the unit and check/clean the screen filter.
Do not permanently remove the screen filter from the valve as it is there to keep crud out of the valve which could hold it open and cause a flood.
