Your air bags should work off of the secondary air system (front). Sounds like the dump valve is not working. I'm not sure where Spartan located it, but FL puts it up near the air tanks.

I have a totally different RV that is 10 years older than yours, but when that happens to me, I push the "store" button and it closes the non working dump valves. It's worth a try.

You don't say what leveling system you have. If it's an HWH system, try the following......start the coach and put it in gear and see if they air up. If they don't.....run the leveling program. Let it fully auto level and then store the jacks. Start it up and see if it airs up.

If it is HWH and you recently dumped the air bags MANUALLY, this can throw the air up sequence off.

I agree with Mark and Don. The air dump valves are controlled by a 12V signal from the control panel that opens/closes the valve.

I'm not sure about your '15 Anthem...but...my '18 Anthem has this panel mounted on the driver's side in the generator compartment:

If all ese fails, it allows manually inflating individual air bags so you can drive to get service.

Take care,
Stu
