Auto leveling not working

When I turn on the level system I get red lights and the air light flashes and the warning buzzer will not shut off. Any advice as to the reason for this?

What is your air pressure showing on the dash pressure gauge?

Are you pushing the "AIR" button once, or twice?  One push turns on the system - the second push puts the system into AUTO LEVEL mode.

Parking brake must be set to activate leveling system.

Below is a link to the HWH 600 Series Service Manual.  It contains a excellent trouble shooting section.  Anytime you experience unusual behavior from the system, your first step should be to run the trouble shooting steps exactly as printed.  Do not skip steps.  In most cases, by doing this, you will be able to isolate the problem and find a solution.

I am pushing it twice
The air pressure stays good when I do that but I do have air pressure loss when using the brakes when I am moving around the lot and using brakes. I have to stop and let pressure build before I can move. I haven't found any air leaks yet

I recommend you run the trouble shooting steps in the manual linked above.  Start the engine, let air pressure build up to the point where the dryer purges and the compressor unloads (usually about 120 psi), then leave the engine running while you do the trouble shooting.

I was thinking the buzzer sounds any time the ignition is on and the level system is activated.  ( I have deleted this annoyance on mine)  The red lights on the HWH panel will blink until the coach is level and then will go solid red.

There is a delay in the hwh panel when a "raise" function is requested by the leveling computer.  60 seconds or more before anything happens on a "up" notion.  Down is quick.  Raise mode has a delay
