Hydraulic kickdown stands

[criopt]

Hi to all!
I have a problem with the kickdown stands. After they did not want to retract even electrically everything was fine, I tried to open the four emergency t-screws to manually retract the jacks.
But no move at all. The systems is one of these HWH. In the manual the hydraulic plan talks of a retract valve that, so far I understand it, should with a spring mechanism and pressure allow changing for retraction/kick out. I assume this valve is blocke, but no iea where to find it. Is it maybe situated insie that big aluminium block where the four valves for the jacks are mounted on?? Thanks for any help and tell me if you need more info!
Kind regards from Portugal
Olaf.

Is this a trailer or a motorhome?

Sounds like a MH. The OP needs to go to HWH in Moscow, IA, for service. They will make it work properly.

Sorry for the delay guys, yes it is a Motorhome. Unfortunately it was shipped to Europe. Where it is located now there is now way of getting a Service like the next 2000 miles... so we have to do it ourselves. We already had to rebuild the electronic control last year from the scratch to avoid buying new jacks...
We located a small valve on top of the block where the U shaped tube is mounted on to. This valve was obviously stuck and its mechanic inside was only moving very rough. Though we already ordered a new one at HWH we gave it a try and cleaned it. After cleaning we could retract the jacks with the four emergency valves, but then after some tries with retracting and lifting it obviously got stuck again. We are now waiting for the part and hope that after the replacement everything goes fine. I add some tech details later here so this post can get useful for others as well.
