HWH Jacks not working

When I stored the jacks yesterday, I didn't see that a heavy wood branch was on the right read pad. The jack didn't retract all the way. So I looked underneath, saw the problem and removed the branch. The jack still did not retract further. The warning light on the control panel for that jack was still on. I hit store and it only clicked. I hit extend and the same. If I put a jack under the jack the light goes out, but comes back on when the jack is removed. I checked for fuses and couldn't locate one. So I can neither extend or retract any of the system. REALLY need help on this as we are try to prepare to head south for the winter. Thanks, Ike

You can contact Paul (AZPETE) at pfmaddox@att.net or call him at 602-549-3638. He is a Commercial Member and has posted that his phone is always on, and if not answered, leave a message.

He has helped other on this forum and I am sure he can help you.

I shamelessly copied this from another post.

Do you know your HWH leveling system series number ?

Do you have the users manual with trouble shooting guide ?

When you were lifting on the extended jack did you have the solenoid manually opened ?

Since the jacks on a HWH system are retracted with springs, I would think that the branch didn't do any damage to the jack. As Skip, suggested, look in the manual at the troubleshooting section.

It would help us help you if you say which HWH system you have.

You should be able to retract the jack manually in most cases. There are four styles of HWH solenoid valve that I know of. One cannot be released manually, but I think it's a pretty old style.

The other three have a 1/4" nut, a T-handle, or a lever to release the solenoid. Your owner's manual will show you which valve is which so you know which solenoid valve to release. The hydraulic fluid reservoir for the HWH system's vent plug (the one you remove to check or add fluid) might have a handy 1/4" nut driver built in if you need one, but you can use a 1/4" wrench or a socket on a finger ratchet (fastest) or a ratchet handle (still faster than a wrench). The 1/4" nut and T-handle get turned counter-clockwise until the jack starts to retract, but not too many turns (your owner's manual should say how many). The lever gets pushed so it winds up at right angles to the axis of the solenoid valve. In any event, after manually retracting a jack, I have closed the valve afterward. However, thermal expansion could cause a jack to extend far enough to activate the "jacks down" alarm in transit. In that case, you'd have to stop and repeat the procedure to re-stow the jack. This has not happened to me after three or four manual retractions, but you should be aware that it's possible with the valve closed-.

If you have a system with the old non-releasable valves, you will have to loosen a hyrdraulic hose to manually retract a jack. Hydraulic fluid will come out and make a mess you should be prepared to deal with so that it doesn't soak into the ground or screw up the pavement.

HTH...

Got it Fixed?

Thanks everyone. The problem started when I retracted the jacks and a branch was stuck above the pad and jammed against the jack body. I didn't realize what had happened and left the system on in Store mode for a long time. It appears that the system was overloaded and a solderless connection in the 10 gauge wire to the pump melted. I replaced cut off the bad portion of the wire and spliced it together. System is working fine now. E special thanks for Paul for helping me out with manuals and advice.

Glad you got it fixed. Paul warned me not to leave my system in store more than 5 mins or you risk burning out the solenoid windings over time. I think the system will let them stay active for 25-30 mins.
