Update from original post: Frank from HWH support got back with me. After some step by step troubleshooting, we diagnosed the problem as likely being a failure of the Master Relay that is on the left of the pump motor. Our Class C is 9 years old, so the relay may have just aged out. I ordered both a Master Relay and the Pump Relay from HWH. Cost was right at $100 for the two of them. Installation was fairly easy. The only issue I had was killing power to the Master Relay. Disconnecting the chassis battery should have done it, but I was still getting power. The house batteries have a master cutoff that also should have done it, but power was still getting through. It wasn’t until I finally disconnected both the house battery and the chassis battery that I was finally able to get the power off to the Master Relay. Once that was done it only took about 45 mins or so to fix.

Hermmanmullins If you’re at the show, could you show the HWH folks my problem and see if they have a solution? I would seriously owe you a beer.

Manholt I’ve got a call in with HWH Tech Support and on a wait-list for a callback I’m told that the list is weeks long. I’ve printed a copy of the HWH troubleshooting guide. The failure to extend from the stowed/travel position isn’t shown in it I also posted the same question in the IRV2 Forum. No responses there yet. When I Googled the failure, I saw lots on failure to retract, and failure to extend, but nothing on a failure to get out of the travel mode/stowed position. I did check for hydraulic leaks and found nothing. I typically drive the rig for 20-30 miles a month during the off-season and run the generator while I’m out, but I haven’t cycled the jacks since last fall.

Manholt Normally I drop the jacks with the second push of the on/auto button within a few seconds and they work fine. I tried it with a five minute wait between the first and second pushes as you suggested and no change. is there a way to reboot the system?

I’ve got HWH 725 Jacks on a 32 ft Class C. The jacks will not come down from the stored position. With the chassis parking brake on, the first push of the auto/on button brings up the level sensing lights as appropriate. The second push of the auto/on button SHOULD lower the jacks from the retracted/travel mode position, but they stay up. If I press the auto/on button a third time, the four corner “jacks down” lights flash red for a few seconds, the auto/on ligh flashes for a few seconds, then all lights go off. I’ve found information on a failure to extend the jacks once they’re down, but not on actually getting them down from the stored/travel mode position in the first place. I’m on the callback list from Tech Support at HWH, but that’s a weeks (plural) long wait. The HWH Service Manual does not have anything on this failure mode. Any help would be appreciated.
