HWH Slide Will Not Work

Our slide suddenly stopped working.
I have changed the converter (stock original was kicking the breaker) and batteries and still the slide does not come out.
I'd like to fix it myself.
I should add that leveling legs are still working.
Also, the slide has been creeping out while in storage.
The leveling and slide system is HWH Series 200.

No, I am pretty sure I just hear a faint "click" if anything and that may only be the rocker switch itself clicking plastic on plastic.

Start checking fuses... pull out your manual and see which fuses are linked to the hydraulic system... its gonna be on the 12V fuse blocks. On mine that is a bank of push ones up over the stove or a series of those auto-pull fuses up under the dash, in my 02 Winnie Adventurer, yours might be diff of course...

Oh, yes, I checked every single fuse I could find, even the in-line ones under the back of the coach, although there could be one I missed. What's confusing is it would seem the levelers would be using the same fuses and the leveler works.

Most slides and levelers feed from BATTERY vs Power Center, so there are BREAKERS (might be 2, 3, 4?) next to battery/ adjacent (MINE under step, by battery, but vapor seperated), usually within 18", just follow the POS+ cable. Smaller (20, 25,30a) usually have a small button that pops out on small end of breaker when tripped. Some circuits can be auto-reset, but jacks/ slides usually manual reset to prevent killing people. Good Luck.

I just changed out the batteries, yesterday. Back to the battery box.

Okay, followed what I could. No reset button. There is a 40 amp coach breaker under the dash pad, but that has not popped.

Using a VOLTMETER, test your breakers and solenoids. May need helper to activate switches. BEWARE CRUSH HARZARDS/ RISKS. My slides solenoids were replaced because they would stick engaged and thus trip the BREAKER; my BOOST SOLENOID was opposite and would CLUNK but not connect; new parts fixed both.

I am leaning towards doing as you suggest, simply because of age and critical need for these parts to function, just need to find a tech. I got leaking seals, as well, so I intend to have all those replaced, as well. Honestly, even if those replacements don't fix the problem, I will feel better about being out on the road. I reckon we'll just tough it out for a couple of weeks, then take it to the shop where we live.

One more thing, it may be a Pandora's Box, but there is a junction box below the sofa and I know it's connected to slide wiring. Have you ever heard of anything so user inaccessible to have something like a breaker or fuse?

Thinking about JUNCTION BOX UNDER SLIDE COUCH, I would more suspect that is for lighting above the couch?... but, cud be wrong. If slide hydraulic, usually no related wiring in the slide itself.

Okay. Update, after I finish my morning coffee, I am going to check the hydraulic fluid level. It has come to my attention that the slide might be holding up because of low hydraulic fluid pressure. I finally found the pump and solenoids.

Is it permissible to use a seal leak product like Lucas to top off my Hydraulic fluid? Otherwise, just a generic hydraulic fluid or Dexron II?

i have a 2001 Itasca with HWH slides.

1) I don't think low fluid is your problem as when I serviced mine with a lot of leaks the pump would still make some noise even when very low on fluid.

2) I would not put any leak seal in your system. You have a very old unit and the seals on the cylinders most likely need replacing.
I rebuilt mine for about $10 each ( I rebuilt 3: 2 on living room and 1 on bedroom slide ).

The hardest part about the job was figuring out how to get the cylinders out.
After they were out, I took the cylinder into a Hydraulic Store and they chose the seals for me. I spent less than $50 rebuilding 3 cylinders. A local shop wanted $250 to repair 1.

If you are low on fluid, it went somewhere, so you have a leak somewhere.
If you decide to fix it yourself, look for a writeup I did : search for my name, or HWH slide.

Feel free to private message me if you decide to rebuilt the cylinders.

But it is my opinion that if you don't hear anything when you hit the buttons you most likely have an electrical problem.

1) I agree, but the only chance was that the low pressure might trigger a switch. As it is, the hydraulic fluid is low normal.

2) Leak seal is a Hail Mary, for sure. I was wondering if someone might have tried and used it.

I just may try to rebuild them. My biggest challenge with doing my own work is the antagonism of the city where I live. My driveway is about a 6% grade; there is no way or room to park my 37 foot rig there. My local city has an ordinance against any RV parking. Even though there are stipulated exceptions, the local police happily write out tickets, which I have to challenge to get dismissed. Their real target is homeless RVers, but the "zero tolerance" mentality makes my RV a target. End rant. Anyway, the point is is frustrating for me to get somewhere where I can do such work.

BTW- The HWH manual is very clear that one should not use jack or ordinary hydraulic fluid, but they say nothing about the seals. When we talk about seals, are they just o-rings?
