HWH Leveling Failure

[sdcyclist]

I had a most interesting failure of the computerized leveling system on my 2006 36FDDS last weekend. I pulled into Cuyamaca Rancho Sate Park for the weekend and leveled the coach easily. When I came time to leave on Sunday, the leveling jacks would not retract--in fact the entire panel was dead.

After reading the HWH manual, I could not find instructions for manually retracting the jacks. Does anyone know how to retract the jacks in a emergecy mode?

We were stuck until I remembered that the center console seemed to have some resistance when we pulled it out to start the genset. I pulled off the side panels and using a flashlight, I looked for the HWH computer panel. Once located, I noticed that there was a white plastic multipin connector missing from the touch pad panel. Ah, ha, there was the connector sitting on the floor. I re-attached the plug and a miracle occurred--the little red pilot light lit up! Problem solved!

sdcyclist,

Thanks for the tip on this, I'll remember to look for that loose electrical lead the next time my HWH panel is dead.

You shouldn't have any trouble retracting the jacks if the pressure is off on the system, because the jacks have springs on the side that pull the jacks up when the pressure's off. Worse comes to worse, I think you could create a leak by cracking a fitting on a hose on one of the jacks, catching the fluid and letting some of the pressure off. I haven't tried it, but this might be an idea to get the jacks up. Some other readers might have better ideas on the jacks, since the solenoid valves I think control the slide only (maybe they control jacks too?)

There are solenoids with bleed valves for the jacks also. You should have a diagram in the compartment by the pump/solenoids telling you what each solenoid is for. If that connector comes off the control the slides will not work either.
