What brand leveling system?
I do not believe you mentioned that.
Ours has a Lippert system (LCI).
There is a way to retract the jacks in their troubleshooting section. You'll need an allen wrench (I think 5/32"), a drill motor, socket adapter for the drill chuck, and a 7/16" socket.
Uncover the plug at the end of the pump's motor over its shaft end, in there you'll see a hex the socket fits onto. With drill motor, spin pump to retract all jacks. You have to follow their recommended procedure, and turn the set screw in the hyd logic valve, ours had to spin counter-clockwise.
One time I had to replace the "level" module, I called it the brain of the system, it measures you being level, then controls which jack pairs do the work, when in auto-level.
Ours was located inside one of the basement outside compartments, attached to that compartment's roof. It's about 3" x 5". I don't remember if the wall control panel had lights though. A reset may be all you need. Hope this helps.
