Your Power Pack may be failing. There may not be enough return pressure in the lines to trip the solenoid. Call Lippert. I had issues last year, they were great to deal with.
this will sound like a crazy question, but what colour is the cap of the reservoir? It was a question they asked me, I told them mine is yellow, that seemed to mean something to them and I got my Power Pack replaced under warranty, even though it was past date.
But like I said call Lippert.
