Hydraulic Slide and Leveling Jack Issues on 2006 Winnebago Adventurer 35A

[SuperGDad]

Hi

So I recently rescued my father's 2006 Winnebago adventurer 35a. Everything's in pretty good shape it was winterized for 2 years without being opened.

Right now I'm doing some basic troubleshooting just to figure out the sides and the leveling jacks.

Just looking for some thoughts on where to start looking or what can be done to figure out where the exact problem is. And or maybe some questions I'm not thinking about.

Here's the scenario

- The kitchen side opens slowly and slightly crooked but straightens out when it's fully extended. It also closes and almost tight with a little manual tug on one side.
- bedroom goes out slowly but will not come back in.
- the big living room moves about an inch in and out but nothing more than that.

The leveling jacks won't go down at all.

I do have three batteries all pushing 14 ish , and I've tried it with the engine running and without and even boosting from the SUV.

The whole system sounds like it's trying to push hydraulic fluid around. There is hydraulic fluid in the reservoir tank to correct level but it never seems to change level to me? This is the tank/pump that's underneath in the engine bay.

Obviously some of it's getting through otherwise nothing would open or close.

The interesting part is the solenoids are behind the living room side out... I'm not sure how to get there to look or even take one apart if that living room doesn't extend? See picture.

Theere is a hydraulic pump/reservoir and what looks like maybe a solenoid underneath in the engine bay.

I guess I'm just looking for some guidance on where to start looking for what the issues are and what people's thoughts might be?

I am very mechanically inclined but the system is new to me and I've spent a few hours exploring it and just frustrated.

I'm sure this will generate some questions so ask away? I appreciate all the guidance and help.

I would tackle the leveling jack issue first. If the RV isn't level it will amplify slide issues. Both systems are dependant on the parking brake engagement switch being closed. I'm not familiar with your RV, but the slide controller on mine flashes an error code if there are issues.

Suggest you work this as two different but related problems and start with getting the leveling first.
They may both use the same hydraulic pump and much of the equipment but one item to keep in mind it hat getting the RV levels and supported squarely can avoid any twist in the frame that might make th eslides a bit crooked to drag more than needed.
That getting the jacks working will also do a lot to sort out some of the questions of why slides are not workign as they should? One trick to ocnsider when movign the slides sounds a bit "off" as we tend to not want to stress things we are not sure about.
We may fall into a habit of only pressing the slide switch until it gets all the way out or in. We don't like to think we would strain something or burn out the motor?
But this can be a problem if we do it too much and too often. By nature there are often two item on the lides, one on each side to move it out or in and they don't always work at the same speeds on each side! so if we run it out and stop too soon, we leave the slow side a bit crooked. Think of what happens when we do a dresser drawer and get one side out too far? IT jams and won't move, so we want to avoid this on the slides.
They are aware of this problem when they build the system and there is a bit of "slack" built in to let us hold the switch until the slow side catches up ! Something like a slow 1-2 count maybe? Just long enough for both sides to get there? Careful but not TOOO careful.
That "might" get the slides a bit better if one side is too far behind?
But for the really best inf on troubleshooting the jacks and slides, it may be best to seach online for manuals. I think you will have an HWH brand hydraulic and they do have really good manuls online.
But opne of the first points you will need is knowing which "series" you have. Teh online manuals will guide you on how to sort which series and then you can go to that section of the manual. Familiar with flow charts as a way to sort trouble?
Really good method but we have to go slow and start with finding the right series to follow!
I might start with the jacks as a way to assure there is not something in the RV chassis putting stress on moving the slides. Again, it is kind of like cabinet drawers in an old house? They work better if it is all nice, level, and straight!

Wish you luck on the chase!

Thank you both for your reply, I'm away for a week so I won't get back at it after today. I definitely understand the stress and the twisted drawer comparison that makes sense. I'll try and get the jacks down. I do have all the manuals etc so I guess I'll just start chasing what the possibility would be why the Jacks aren't going down. From what I am reading it could be as simple as just a sensor.

The park break does show engaged. And I'm only using accessory. Again the jacks just whine and sound like they're trying but they never actually come down. I wonder if hitting them with a hammer like the old starter motors works...

Stay tuned I'll update eventually when I get back from work! In the meantime if other thoughts or ideas please let me know

It's a 6000 series. I know that.

Fully understand doing it when time is right for you on your end! I often set here waiting for something to hapen and then three things comeat once, so I try to push forward any info that shows up and let you get to it as fits on your end!
Got one easy looking and one that may last more than a week.
The quickie idea that aI came back with:

But if no joy there, this is the DEEP thinking one as it has things like sorting out if you really meant 6000 or it is really a 600 and they give pictures! YEAH!
With 23 pages, that should have some good deep thinking hints?
My problem is that I never remember much from the last read through the manuals, so I forget the small stuff that makes it all work!
I'll let you start with looking at the pictures to see if it matches your controls?

That trick to clear it's mind might be great- if it works!

Good luck on the trek for when you get there!

625 system lol. This is a short operators manual but that's about all I have besides Winnebago book. I'll see if I can dig up a manual like you did for this system. I have no problem reading it page for page old school. I did discover today that there was little to no hydraulic fluid in it.... Yeah I know I should have checked that first and I said I did however... I was looking at the wrong tank lol. I was looking at the hydraulic over electric brake system... So now I've got it filled up however after cycling it a few times hoping to get rid of the air bubbles and prime it I've had no success. Maybe impatience? Not sure how many times I should cycle 15 to 10 seconds on the leveling jacks and then let it sit for the air to come out? I also agree and then trying to solve the leveling Jack problem before I solve the side out problem. Except the 625 system is behind the living room side out lol. Very difficult to get to when that thing is closed and refuses to open.

I don't leave for work till tomorrow so I'm going to give it a shot in the morning and see if the pump magically primed and some hydraulic fairy came and sucked out the air.

I guess it's just such a weird combination of some things working and some things not but they're all on the same system. I'll try the board reset maybe it's just confused with me messing with it.
Also is there a way just to tell if the solenoids are bad besides switching them around? And is there a way to tell if the shuttlecock is blocked? I did read that that could possibly be stopping the leveling jacks?

Thanks

Still lots of questions that I have little confidence on my knowledge! It start of with not knowing for sure this is the correct manual that I recommended!
It is for the 600 series, so does that include 625? I noticed one big thing that may make it not the bestif there is a manual for 625 but unsure on that. I notice this involved RV with air dump, so is that the best manual for you if you do not have air dump or do they pan for those users to just ignore the air dump. I've not used the manuals from HWH to get that familiar with how they think, so be aware fo those limits.
I've read thorugh a few but not done the actual work, so I lack that hands on stuff!
My HWH experience has been pretty shallow and mostly involved getting fluid right!
For the solenoid question, I might assume it comes down to finding if the power going to any one specific solenoid gets there and then does that solenodi open and close as it should. It can be lack of getting the signal to the solenoid or physical problems with the solenoid that requires changing it!
What I have read on other post questions has seemed like they covered issues really well and I trust they did it in a good organizedway---but I've not done it. My first jack problem was before internet, if that tells you anything about what I still remember.
I DO remember it was stinking cold and I was laying in the snow!
I think I might see if there is not a bettter manual as this is for one with four points of air leveling, not hydraulic????
I'lll do a bit of checking for something that should match your RV better. Maybe what you have in the picture is correct but no reason not to check for more/better info, if we can find it!

Answer from Copilot:

Will be chassing that rabbit!

 

[Morich]

Not found the manual soucre yet but this may be handy on getting the slide moved and they seem to promote calling them:
This site gets this response?

Maybe a good place to try calling when time is right?
This shows up as a home site for HWH:

HWH Leveling Systems

Not finding direct link to manual for 625, suggest maybe better to let you call to ask about getting the stuck slide to move out of the way as well as ask about finding the correct manuaol. That might help to get me out of the middle as that can create problems at times!
EDIT! I think this is the correct one and what you have but if that copy is damaged, this may be the one for online info:

https://cdn.shopify.com/s/files/1/0674/3490/5796/files/625_Series_Service_Manual_-_ml35963.pdf?v=1735764686

Not to cut this off but getting too many people passing info is one way to get in trouble!
I'll be watching but info from them is certain to be better!

It could be the shuttle valve ! Switches from from the Jacks to the slides

 

[Uadockie]

I have a 2006 ADVENTURER 35A also HAD the same problem with Jacks not going down

 

[SuperGDad]

Hi all ,

I got a chance to start working a little on it today and wanted to update- I managed to map what side-outs were what - Right Rear - Bedroom, Right Front - Kitchen and then Left Rear and Left Front for the living room. Are there two for the living room because the size or one is in and one is out? I cant find than information anywhere. I removed the shuttle valve and it looks okay and operates but I am going to clean it and replace the rings. Next step is testing all the solenoids. I have enough access to remove them unless there is a better way to test them - Note the control module for the whole system is on my workbench, i had to remove and unplug it to get to everything behind - until I get that side at least out.

Also is the cap supposed to sit that high? I cant thread it lower. see pictures

and I only have three solenoids for the level system?

thanks all

 

[SuperGDad]

Update to the above - top four are the leveling solenoids and bottom three are the rooms - I removed them all. replaced o rings, cleaned them and bench tested. Also the shuttle valve. just need to put it back together and see what happens next. hoping that everything resets and without a pressured system the jacks and rooms will be able to be manually pushed in and then magically work after i put it all back!

 

[Morich]

I've lost track without reading it all, but did you come up witht he correct manual for finding the step by step troubleshooint?
If not, this seems to be where I would go:

https://www.hwhcorp.com/ml41240.pdf

The start with the manual operation to test it as correct before going into the more complex issues of automatic leveling.
Good to check to see the wheels go round before we try to ride the bike??
Wish you luck!

So after a couple days of messing around. I think I've read every HWH manual going. I can't seem to find a specific one just based on the side outs however. It's still extremely hard for me to access any of the solenoids or the hydraulic pump or anything because the living room side will not extend. There is 10 solenoids on this system. For for the leveling jacks and six for side out. I have removed them all. I thought that would make it an open system and I could slide out manually anything I wanted..... I can still not manually extend any of the rooms. From what I am reading and learning it's because they are hydraulically locked by a synchronization cylinder for each room? Which is tomorrow's job I'm just going to undo the hose lines on it and see if I can manually just pull the living room side out. This will allow me to have complete access to all the solenoids and the back and check everything from wiring right through. I'm kind of in a catch 22 where I can't put the solenoids back even though I managed to get them out without pulling the side out. Lol

My question this evening is this... I read and it was suggested somewhere that there is a physical lock on the living room side of this Winnebago. That you have to lift it about an inch to manually overcome a little trench that the room sits in before it extends. The suggestion was just to carefully and properly raise the living room half an inch to an inch clear this physical lock. Apparently the hydraulic system lifts it a little bit and then puts it out to make it a lay flat floor.

I am absolutely blown away that there is so much information on how to emergency retract these sides but there's no information on how to extend one of you need to manually. It's got to be a simple way or something simple on missing?

I have calls into HWH and emails just waiting for them to return.

Thanks again for everybody's suggestions and help. I'm also kind of documenting what I'm doing here so if somebody else has these issues at least there's something.
