I assume you're saying that when you push the rubber button to recirculate the reservoir, nothing happens, no water pumps through? Do you hear the pump make any sound at all? The motor sits on the rear of the toilet ledge covered by a plastic cover. Double check the wires under that cover. Is there anything else in the camper that normally works on 12v that is not working like the overhead lights? The light outside the front door?

The pump operates on 12v. You may want to test it by running a battery charger like you would use if you wanted to boost your car or truck. Hand held type that you plug into a wall socket till it's charged and then use the battery cables or connectors on the pump contacts. If it works you've got a bad connection down the line somewhere. If it doesn't work, the pump is bad.
