Slides creeping

[creeker]

I just bought a slightly used 2015 Alpine 3536. When all the slides are in, within about 24 hours two of the slides will creep out about an inch or so. I hit the button and the slides immediately come in but will creep out again within a day. I returned the rig to the dealer and after 10 days I was told no trouble found all is OK. As soon as I drooped it off at the storage lot I noticed that two of the slides had already moved out.
The service manager then told me that this is a known problem and Lippert is working on it. Has anyone experienced this issue and if so was it a leaking system or a problem with the pump not holding the pressure of the slides and the level up?

The times I've seen it, it was the solenoid in the manifold. Replaced solenoid and all was good.

I had a problem with mine where the bedroom slide would come out about 6" when I raised the landing gear. I called Lippert and they suggested a manifold or Solenoid problem. I've heard of people finding small metal shavings which prevented valves from closing properly. Have also heard that air in the lines can cause this, but my experience with hydraulics was more of a hammering effect with air in the lines. I also found data that temps below 35 degrees can cause erratic operation, this appears to be the problem I was having. Obviously that isn't your problem this time of year. Have you tried shutting off the valves to those slides at your manifold to see what happens.

Not sure which dealer you're working with, but I always had good luck with the service department at Apache Village when I lived up there.

I am working with Apache Village but I'm leaving for Florida in three days so they can't get me in but tell me i should be fine to travel.They just suggested i stop occasionally and hit the slide in button.
Regarding the response from chuckster57, if the solenoid is the problem would only the slides be affected? The level up seems to work fine and doesn't drop while towing or while sitting leveled.

[chuckster57]

There is a number of solenoids, so you can adjust the level up. The rooms operate from a different one.

A follow up. There was one hydraulic ram leaking internally. The dealer replaced it and so far all is good!
