Erratic HWH leveling

On our initial leveling at the last several stops the following have happened:
1. As the air was dumping the jacks started down for a second before the bags were empty. The jacks stopped and then started correctly when the bags were empty.
2. The air bags emptied but the jacks did not deploy. The system was recycled and the jacks deployed correctly.
3. The air bags emptied and the jacks started down and stopped. A few seconds later they started down and finished leveling.

At some stops between the above stops all worked normally. Any suggestions as to what might be causing this erratic behavior?

Jerry, I know you modified the drawer for the HWH a panel, have you checked that the connector is properly seated on the back of the circuit board? I would look at the connectors on the control box in the compartment behind the front passenger side tire. What you describe seems like a loose connection. I would also make sure the "Parking Brake" light is staying on, if it was intermittent it could cause the problems, check that wiring.

When our HWH acted erratically on Auto, it turned out to be a loose ground connection on the HWH controller box.

My HWH system seems to have gone to sleep and the only way I can operate it is with manual switches in the HWH bay. I can operate all 4 slides and all 4 smart drawers with the manual switches but there are no manual switches for the levelers. My coach is operated through a SilverLeaf system that uses a digital display for selecting and operating the systems in the coach. I have had email communications with one of HWH reps, he gave me things to check that are electrical. I checked the things he listed and found every thing to be good. He could not offer any further help due to the SilverLeaf system. I have been in contact with SilverLeaf but so far no one has an idea on what is freezing up my HWH leveling. I have all of the drawings available (I think) but none of the troubleshooting sections discuss my issue. When I turn on the auto leveling option the display messages me that “auto leveling is in progress” but nothing is happening, after a couple of minutes it tells me that the system is “inactive”.

Any ideas are welcome. Is there any way to manually deploy the jacks?

Since you have the Silverleaf system to control the jacks, does this mean that you don't have the HWH control panel? The HWH control panel has switches that will allow you to operate the jacks manually. (Assuming the HWH control box is working properly.)

There was a thread on here a while back about ways to bypass the HWH control box in the event it fails. Based on input from other posters, I built a box that I can connect to the wiring harness and control the jacks manually in case the HWH control box fails. Which mine did a couple of years ago.

Here is the thread:

I had that problem a couple of years ago. Turned out to be a fuse in the battery compartment. A 15 amp mini fuse. Check all the fuses in the Battery Compartment. Also check fuse bank in passenger side holding tank bay.
