HWH Active Air knowledgeable tech/shop on the West Coast

If teh System in teh 2024 DSDP is the same, When I was discussing the leveling routine with the TECH at CPU, if I remember correctly, he indicated that when you start the retraction of the jacks in the Accessory Key position that you let the cycle finish before moving key to Run/starting engine OR after start press Store again to get to ride height. Moving ignition switch from Acc to Run interrupts the Air up process.

My $0.02

My problem occurs no matter how I dump the bags. Auto air & auto hydraulic both auto dump the bags before leveling. ”Store” is always pressed to get back to ride height no matter how the coach was leveled. If you look at the photos of the bag pressures you will see that the rt drive will not fill until I drive a few hundred feet.

On my coach which is NOT HWH levelers, it uses shuttle valve(s) to redirect air from dump to air up. Could you possibly have a sticking shuttle valve? I had this issue a few months back and the fix for equalizer systems is to put it in drive and for some reason that sends some signal to close it. I think it's a 12V signal.

Have you tried complete power off on the coach? 12V (salesman switch) and also chassis for say 5 minutes to allow everything to reboot? There are still some 12V loads that remain on, the only way to kill those is disconnecting the battery manually or using a cutoff switch if you installed one.

I suppose the shuttle valves (if I have them) could be the problem since driving the coach a few hundred feet seems to temporarily fix the problem but all bags with the exception of rt drive air up fine after “store” is pushed.
I have shut off the salesman switch and the chassis main switch with no change In operation.

I certainly appreciate all the help and suggestions you all have been giving me!

I like the sticky valve theory. I had one jack fully extending totally out of balance with the other three and it was just a sticking valve although mysteriously it only happened on auto-level. Manually it worked just fine. HWH replaced it for $187 (plus of course the $2500 to get there and back). Might be a similar arrangement fir the bags.

I’m sure you saw my post. Maybe you have a bad air bag? All of mine are getting replaced today.

Yes, thanks. I’m headed to Freightliner in Sacramento next week to have the bags checked out. If I need them I’ll report what it costs to replace them here out west.
Like you, I just find the need to spend $$$$ on the coach. Especially during the holidays!
