I'm am trying to figure out why my slides and jacks are not working. I have had three Techs try to figure out why with no success. I have replaced the circuit board and the jack control panel from HWH. One tech was able to get the slides in by crossing/shorting the pump solenoids so I know the pump works. The last tech called me today and stated the system is not recognizing it's in park. The main starting battery needs replaced I know. I have resulted to charging it before starting. Could this be the culprit? Any suggestions would be appreciated.

I’m thinking you need to find the wiring diagrams for the coach and quit guessing (assuming you know ho to read and use a wiring diagram. But having it for others to review would be helpful - in particular the pages that show the slide-out and HWH wiring.

From what I’ve seen, Winnebago does a good job of documenting their coaches on their website.

Just a thought - for the slides, make sure all your basement doors are closed and that the door switches are being held open properly. For some coaches the slide-outs are interlocked through the ignition - key has to be off (coach batteries need to be good for slides to work).

For the jacks, make sure you have plenty of

If you go here 2005 Winnebago System Diagrams you should find the HWH hydraulic and electrical diagrams for your coach, in case that helps.

Thank you I'll start looking on the HWH site as you suggested.

parking brake engaged? and if you think it is press the foot pedal down a little farther.

There is a parking brake switch located on the arm of the parking brake pedal a little ways above the pad. On our 2005 Adventurer 33v there is a thin blue wire attached to it. When engaged his switch tells the HWH system that jacks and slides can go out. Make sure there is a good connection by the wire to the switch. We had this problem and replaced the switch with:

There might be a diode hidden in the wire bundle between the control and the floor. It should be shown on the schematic. Mine burned out and shut down the system.

Hi Everyone,
My 2005 just started doing this. We were camping, jacks worked fine, slides went out fine everything was well until we went to leave the site.

The smaller bedroom slide went in albeit slowly, the kitchen pretty much the same. The living room would not budge. I had to go through the manual steps to crank it in by hand. (What a job that is) The jacks retracted just fine, but I figure the springs took care of that.

Further investigation showed my fluid level in the tank was VERY low. No major leaks anywhere to be found but some minor weeping at connectors etc. I filled the tank with the correct fluid, but now only the bedroom and kitchen slides work. The jacks go down, but will not lift the RV. No joy with the living room.

My question is this, it is possible that I have air in some of the lines which seems to make the most sense to me seeing how the system is designed? I've looked to see if there is a method to bleed the system but can't seem to find it anywhere. Does this have to be done, or will the air eventually work it's way out of the system?

Thanks for any feedback!

Hey Bob -

Always better to start a new thread if your not dealing with the same issue - it confuses the answers.

But you’ve very likely hit the head of the nail - there is very likely a bleed procedure for your system - normally it requires topping off the reservoir, then fully extending all cylinders, then rechecking the fluid levels. If/when cylinders fail to extend, recheck fluid level.
When all cylinders fully extend, recheck fluid level. If you can get them to fully extend, then to retract and start over until you either find a leak or you no longer need to add fluid.
When you reach a point where all cylinders extend and retract as required, your done.
If the cylinders get to a point where any of them don’t fully extend and no more fluid can be added - it’s time to figure out if there is a bad solenoid valve or something is plugged up.

matt.hardin and Bob 32725 you both should contact Paul Maddox (aka azpete) regarding your problems.

Paul works for HWH and is a valuable contributer on this forum. You can search for him on the space above.

Bob_32725 · 08-05-2021, 11:41 AM

Thanks for the response guys. It's appreciated! I'll try contacting Paul as suggested.

Just fyi, I believe that Paul's had some health issues recently, so he may not be as responsive as he usually is.

kb2ztx · 08-07-2021, 07:34 AM

As said few items to check.

Definitely a good battery and/or vehicle running as the pump runs off the engine battery.

Emergency brake on and controller showing it. Unless it sees the brake signal the pump and controller wont engage at all.

azpete · 08-11-2021, 07:31 AM

first thing to check is the two bolts under the mounting bracket. these bolts hold the pump assembly to the bracket. they are also the main ground to the hwh system.
always run the engine when leveling if you suspect your batteries are low. marginal batteries can burn out control boxes, 12 volt relays, and pump motors, so that something to consider.

to bleed the jacks, fill the tank within 1 1/2 inches from the top. run the jacks down, and back up a couple of times without lifting the coach. they are self bleeding, so that will take care of that.
if the room is retracted, open the retract valve and run the pump for 8 to 10 seconds, close it up, hit and hold retract for another 5 seconds. then very carefully run the room out. if it get out of whack, stop!!!

call me at 602 549 3638 anyone is welcome to call me. i have had some health issues, but i believe we have them under control till next time.

i work full time for hwh. i do not solicit part sales on this forum. i do not do service work anymore, except at rallies, or by assignment from hwh corp.
