Could it be a bad inlet valve?
It could be but it also could be a number of other things.
Check that a wire has not come loose during the move.
I would check that the float is not stuck in the up position, the switch underneath should be activated (held closed by the float rod)
If OK
Check that the water inlet valve has continuity (approximately 1000 ohms)
If OK
Check if the valve gets power at the start of the cycle (120 volts)
If yes
Valve is either shot or it's input side filter screen is clogged up.
Also check to be sure the unit is getting water. Loosen the fitting at the inlet valve to see if water starts dripping out.

If no voltage
Check that the float switch is actually closed (0 ohms), just because the switch is activated does not mean that it's contacts are closed.
Check that a wire has not come loose at the control board.

METER
If you do not own one I would suggest you purchase a meter. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.

There is a good STICKY at the start of this forum about it's use.
