Bedroom slide creeping

[Slufoot733]

Our new 3150RL has been parked in my yard for about a month now and twice I have noticed the bedroom slide has opened about 4 or 5 inches. It's like a valve is leaking and fluid may be leaking back into the hydraulic cylinder. Now if this continues I will definitely return to the dealer(35 miles away) in the spring. I was just wondering if anyone has encountered this and if so, what had to be done? Does it have anything to do with the hydraulic bypass switches on the side?

Thanks in advance for any info. MERRY CHRISTMAS everyone.

Could be one of three things, check valve in pump assy leaking, leaking hydraulic hose / fitting, or leaking internal seal in any one of the slideout cylinders. The selector valves I doubt have anything to do with your problem as they simply block flow when closed to prevent any given slide from coming out. Try closing all the selector valves, that would at least isolate the pump from the rest of the system. In other words, when all the valves are closed and the slides stay in, then the check valve in the pump assy is the culprit.
PS Check your hyd fluid with the slides all the way in ... should be about 1" or so from the top. If it was low and you want to bleed the air from the system, simply cycle he slides full out to full in about 3 times ... the system is self bleeding.

It is one of two things the bedroom slide cylinder or the pump. I had the same problem they first changed the bedroom slide then the pump and no more problem.
