Do you have the books on the RV and looked at how to do the slide. There are usually some steps that have to be done before we do the slides and if they are missed, things don't work!
First step seems to be to level the RV and leave the system on. Have you done that and did the leveling work correctly?
When you question what to fill the pump with, it really needs to be done correctly and using the right fluid as the manual says, so it really sounds like you may simply be guessing and that is really bad when dealing with something as different as an RV. Check the HWH manual for type to use and how to tell when it is full as it is easy to get it wrong if you open the wrong plug! Don't use the plug on the side!
A leak sealer sounds like it would NOT be something to put in a hydraulic system but the correct thing will be listed in the books.
A switch for the hydraulic pump, placed in the compartment with the water pump really doesn't sound like anything most would do. One would have to get out, go to the compartment to turn things on and then go back inside to level and do the slides???? Not a place most would want to put a switch for the slide!
There is already an ON and OFF switch on the controls, so I would not expect there to be one added later!
If you did not get the owners manual, it is here:
Down to page 2-19 is the slide and jack info.
We have had it for about a year and been using the levelers and slide successfully for well over a year, now.
I have the original and PDF copies of the manual. The manual, as well as the manual from HWH, does not give great or user-friendly references to addressing the "where" exactly of many of these things. Some of it's flat out wrong as far as locations. Online, most of HWH's photos are of a different generation of hydraulics, even if they are equivalents, I want to be sure before I make a move.
As for leak sealer, I will probably hold off on using it, but getting a tech from HWH to call back ("a wait list") is a long process. Since I wrote this I have properly, per the manual, checked the fluid level and found that it was only low-normal, so I might top it off, but not too much. Here is specifically what HWH says in the specific manual for my system:
"FLUID: HWH Specialty Hydraulic Oil is recommended.
In an emergency Dexron automatic transmission fluid can be used.
DO NOT USE brake fluid or hydraulic jack fluid.
Use of these can damage seals.
Dexron automatic transmission fluid contains red dye and can cause staining should a leak occur."
There is a real shortage of ready, available HWH Specialty Hydraulic Oil and HWH, itself, admits one can substitute a different brand. But, again, it's only low normal, so I can afford to wait. I sincerely doubt that most RV repair shops will insist on HWH when filling the hydraulic pump reserves of units they work on, so I suspect that HWH is being proprietary as much as it can with something as generic as hydraulics.
Welp, the switch is for the hydraulic pump. It was missing an inline fuse, I replaced the fuse and it is a manual override for the pump. Unfortunately, it does not fix my problem. The manual switch is typically used for pressure testing not overriding the whole system.
