If you thought you heard all the weird HWH slide stories, read this one.

Due to the current insanity, we have not used our moho since March. Two weeks ago I put out my rear slide on my 02 Winnie Journey DL to wash the slide topper, I left the slide out as I had some stuff to do inside. Today, I brought the slide in, or tried to.
The slide moved a little, moved a little, stopped, moved a little and then the pump just faded away. I figured the thing was cocked in the frame and the resistance caused an overload on the pump but it would cool and reset. I wiggled the slide as much as I could and then tried again, same result. I then put the slide out next time (very slowwwwly) but it didn't really seal up snug. I then attempted to bring it back in. Same deal, it struggled to get within 6 inches of closing and the motor died. SLide was cocked with bottom out 3-4 inches more than top. I made several attempts to put the slide back out but failed

I gave up for the moment and left on an errand, when I got back home THE SLIDE WAS FULLY OUT. No one touched it. When I tried to bring it back in it came almost all the way but didn't have the oomph to close properly and remained crooked. I was able to get it to slowly go back out, and then, nothing. I checked front slide, out and in properly but at the end the pump motor was fading. Fluid level fine, no overheating of pump when I crawled under and checked it.


An hour later after trying to find someone to repair it (I've read too many horror stories of folks trying to manually move an HWH slide in) and having come up empty, I went to the moho to see if the jacks would work. I started it, brought up the air, checked the E brake by releasing and re- applying it. I then ran the jacks down. Pump sounded normal, jacks lifted moho. I released jacks, shut the engine down.



More puzzled and annoyed than ever, I tried the retract switch for the rear slide ONE MORE TIME. Voila!, pump sounded normal, slide came in straight and quickly and sealed shut tightly! I NEVER get this lucky. It was like nothing had ever happened, works perfectly.


WTH happened? Anyone? Anyone? Beuller? I'm dying to know if this is something that happened to someone else also or if anyone can shed ANY light on what may have caused it/cured it. I'm confused as all hell.

Low DC voltage situation?
Loose battery cable? Bad ground?
Poor connection(s)?
Check everything, including battery condition.

Air in the cylinders.

Air can compress, while oil does not.
Running the pump, is pushing oil in the air filled cylinders. The air compresses behind the oil and will hold pressure in them.

While you were away, the trapped, compressed air made the slide move.

After a few cycles in and out, the air is purged, and all is well.

My owners manual says to open or close slides with engine running.

He should check oil level in reservoir when jacks and slides are retracted. If oil level is low, fill to full mark deploy jacks and run slides out then retract all. Recheck oil level, if low repeat process until level remains at full mark.
That is the ONLY way to purge air from the system per HWH FAQ page.


The other and/or issue might be 12VDC lower than 13.8V, which the motor requires for proper operation according to the HWH FAQ page.

When you put your jacks down maybe the slide moved slightly and got it squared up and not binding. Was the rig level when you was having trouble moving the slide?

I'm guessing Twinboat has it right. Air in the system. Is you fluid level the same with slides in as with slides out? Shouldn't change with a double acting cylinder. Air is the only explanation for the auto-deployment of the slide.

Okay, someone have have already said this, BUT: Did you follow the MFG instructions on putting out the slide in the first place? Mine states, yes I know its a different model and all, but. Level the coach, then put out the slides, OH yeah, do this while the engine is running because the pump needs to have the correct voltage going to pump.
Just MHO

The fluid level will change slightly if double acting cylinders are retracted. The rod, pulled inside the cylinder, displaces some of the fluid space.
