slide-out problem

When we put our slide in, it goes all the way in and then creeps back out a few inches on the bottom. Any ideas what the problem might be?

Which slide (if you have more than one) and do you know who manufactured it?

It seams that your slide has to be adjusted as it hits the top first and then pulls the bottom part in. This twists the slide mechanism in an upward movement and when the power is removed the mechanism goes back to its adjusted position, therefor letting the bottom come out. Slide adjustment is not an expensive adjustment and should not take to long to be done by a qualified shop.

We had the same issue on our Dynasty a few years ago. Is it creeping out at both ends of the slide, if so it could be either the in or out solenoid on the HWH manifold block mounted on the top of the motor/reservoir. The slides are numbered starting from behind the drivers

If only one end is creeping then it is your hydraulic ram for that end of the slide. It is leaking internally.

Experienced the same problem with our living room slide last year. We have the HWH hydraulic system. My repair was to replace the retract solenoid, as it was leaking past and not holding pressure on the cylinder. This season it was the bedroom slide creeping in. Had to replace the extend solenoid for that slide. Ours is a '06 model so I'll probably buy a spare when I find a good(or at least better) price as I have two more that will eventually go bad.

the service manal offered for free by hwh at their website will help diagnose this problem. it it creeps out when retracted it is the extend solenoid. if it was the retract solenoid, it would creep in, which would not show up with the slide already retracted.
if it only moves an inch or so, both ways, it wold be the check valve.
hwh will normally recommend replacing both solenoids. that way, the problem is solved about which solenoid to replace. experienced techs, and some informed coach owners will figure out which one to replace instead of both.
the service manual is almost a must before you talk to hwh, it will save about a half hour of questioning.
habitatguy, you can send in the old solenoid and have it rebuilt. you can save money having the old one rebuilt.

Again, the above suggestions are accurate IF you are creeping at both ends of the slides. HWH does recommend changing both extend and retract solenoids but the valve will hold in the opposite direction of travel. Example if leaking outward it will be the retract solenoid not able to hold the pressure. If creeping inward then the extends solenoid will not he holding pressure. If on only end of the slide is creeping it will end up being the ram at that end which is leaking internally.

Respectfully I disagree with your diagnosis. When your slide is out and you want it to retract, you push the button retract. This activates the retract solenoid along with the pump. When you reach the end of the stroke you continue to hold the button for 3-5 seconds to fully pressurize the hydraulic cylinder(s). This is what holds the slide in, along with any locks there may be. When the slide creeps out( evenly as stated above) it is because the RETRACT solenoid and check valve are leaking off the pressure. Just the opposite reasoning applies when an extended slide creeps in. I do agree that the owners manual is helpful. Also the great parts techs at Stuarts will help you sort this out.

then to complicate matters, it makes a difference if its an A room or a B room.
A rooms extend the ram to extend the room. most of the A rooms are below the floor mechanisms. either one ram, or multiple rams. ive seen up to four rams used in a commercial application. the B rooms retract the ram to extend the room. the B rooms are the above floor mechanisms. they are either X arm, or uso chain drive rooms. the solenoids work in the opposite fashion when a solenoid leak occurs.

if you have a below the floor mechanism and if your room creeps on one end only it will be caused by one cylinder leaking either externally or internally. if your room creeps out on both ends equally, when the slide is retracted, it is normally the extend solenoid. if it only moves an inch or so, it could be the check valve. many retract solenoids have been replaced mistakenly. thats why hwh recommends replacing both solenoids. you cant miss. ask stuarts, they will tell you the same thing. it has to do with the regenerative action that hwh uses in its room system design.
