Never heard of such a thing? Is this a hydraulic or electric system?
Turn everything off and disconnect the batter. See if that helps?

That is a new one on me too. I am subscribing to the thread so I won't miss the answer. I am guessing it is a hydraulic system and there is a leaking seal.

i have an electric slideout but a hydraulic leak sounds likely.

Hydraulic leaks seems to make no sense to me, The ram should be fully retracted when the slides are closed? So no fluid in the cylinder. I'm guessing that there is a sticky valve that is not fully releasing to relieve the pressure in the line. Therefore the cylinder is being pushed out as the pressure leaks past. To test it, I would swap the lines around and see if when doing so another slide moves.

Somewhere it's passing fluid. Each hydraulic cylinder has 2 hoses, one for each side of the internal piston. For the slide to move out it has to be loosing pressure on the one line that pressurizes to pull the slide in.

87CrewDually's suggestion makes sense to me. It could be that you need to replace some o-rings? If you replace o-rings, use those that have a 70 durometer rating. I would inspect all the system components for signs of leakage. Is it the same slides doing each time or is all 4 prone to do it with only some of them doing it each time? Did the problem start with 1 slide or did it start with multiple slides?

all the slides do it and it never loses any fluid

O.K. If they are all doing it, then I would suspect the solinoid valve isn't holding the pressure and it's losing the pressure to hold the slides in. (not leaking fluid externally, but internally)
The solinoid will have a thumb valve on it to bypass it manually. It should be near the pump. IIRC it should be turned counter clock-wise. I can check tomorrow for sure or some one else can chime in.

Also check here if you have a Lippert unit.
