HWH Jacks won't go down

oh well. No more time to troubleshoot. That technical manual site looks promising, but I'm off to go camping. Thanks anyhow.

Display panel lights up showing my front being low (which it is). I push the up button, and the "jacks extended" light on the dash comes on, but then goes out as soon as I let off the button. If I push any of the "up" buttons, nothing happens, motor doesn't run. Only when I push the down buttons does the motor(s) run. I'll check out the Technical Manual link in the post above.

Perhaps there may be something here that will help with trouble shooting..

Which system of HWH do you have?
Does the display panel light up?

Slide is opening and closing normally.

With the reservoir a quart low I would agree there may be air in the system. Cycle the slide and jacks several times each to purge the system, then top off the fluid again.

Is the slide opening and closing normally? If not then possibly air in system.

I retracted the slide, but the jacks still won't go down. I checked the fluid....it was a little low, so I added about a quart. Still nothing. Jacks won't extend.

Retract the slide and then try extending the jacks. If the jacks work it indicates low hydraulic oil.
