A quick thought...... I presume that when you moved this the skimmer was emptied of it's water. Did you fill it back up before you turned it on?
The motor/pump of the skimmer might not be strong enough to prime itself. If there is no water in the chambers fill it up about 1/2 to 3/4 and turn it back on. You should see a difference.
BTW WELCOME!
