I have a 99 Winny Adventurer 35c.

2 years ago our HWH hydro slide mechanisms were leaking so they were replaced. Coincidentally, I think a year later I noticed one time the slide was hanging going in. Looked under the slide/above bins I saw a ton of plastic hanging out under the seal. Assuming this was it, I made a knife on a long pvc and cut 90% of it off. It closed.

Here we are again, with it stuck open months later. I tore the whole interior out, hoping it was the wood catching on the carpet. No such luck.

As you will see in the pics, this whole area is 90% inaccessible. I cannot see any wads of plastic in the way, but there are some scratches underneath on the bottom of the slide.

I don’t just want to get it in, I’d like to fix it.

Does anyone have any ideas or similar experiences. The binds are welded in, so there is no getting a closer look at anything besides the edges.

In the second image, can you take those bolts off of the slide to see if there is any movement? Currently, all it does is make the whining noise, and nothing moves.

I was thinking of a taking a long, flat piece of aluminum and running it up under the slide from the inside to try and see if there was anything stuck in between.

Any help or ideas is greatly appreciated. Sorry for the novel.

Without knowing the model # of your HWH system, this is all I can offer: https://hwhcorp.com/ml23521.pdf
This will help identify your HWH system.

When the pump motor runs and nothing happens, it might be the shuttle valve or a 12V solenoid, described in the service manual.

Thank you both for the tips. Ray, I would hope, its neither of those issues as they are new units and just successfully put the slide out, but who knows. Its hard to know what is going on when you cant see most of the operation.

Vereken, Thank you for Paul's contact info. He sounds like the best bet to start with.

My intuition is that there is something stuck in between the slide and chassis as we pulled many sq. feet of plastic out from between the two 6-8 months ago. I assume that is a moisture barrier, but the way the Adventurer was produced, there is practically zero access to any of this area. I am very jealous of everyone that has bins that are not welded to the slide.

Great news, I wanted to give closure to this issue and help anyone else that might be stuck(haha I can laugh about it now) in the same situation. It turns out my retract solenoid was stuck, so that when it went to retract, the pressure was equalized, thus no movement. I woke up in the am ready for some MacGyver work, getting under the slide and looking for what was stuck under it like carpet or the plastic runners, etc, but after watching James's videos on a slide removal it sparked an idea. His RV repair videos are the absolute best, I've watched him take apart and rebuild all kinds of stuff, and i'm extremely grateful that his stuff is out there.

Here is part 2 of that series, but give a watch to any of his vids, he is an excellent resource!

Here is the manual from HWH with the images of the solenoids. Mine was as it appears on here, the lower one was retract, upper extend.
