This video details a problem I recently had with my Lippert Ground Control 3.0 electric leveling system. I received a "ERROR LR Jack". The video shows how I found the problem and how I fixed it.

I have no idea if this procedure works for the Level Up Hydraulic system or not, but you can either contact Lippert or just try it.
