HWH leveling system

New to ForeTravel & Forum.  Bought 97 U295 and trying to level coach.  Works fine in travel mode.  When I stop and park, I push button twice to start auto leveling and nothing seems to happen.  The 4 corner lights glow solid red and Air Operation light glows solid red.  Any help is appreciated.

Notice that there is another light on each side, between the corners.  This is the "low side" light.  If none are on, then it thinks the coach is level. 

Try this.  Push the up button on one of the sides.  Once that side gets high, the opposite side should go low and illuminate the yellow light.  Then try auto level and see if it fixes it for you.

Welcome to the Forum and the HWH leveling system.  Rest assured, it is not rocket science.  I linked below two tech documents that will help you determine if your system is operating normally, or if you have a problem.

First link is the 600 Series Service Manual.  Start at the beginning, follow the trouble shooting steps exactly as written.  Make sure before you start the tests, that you have full air pressure in all tanks (120 psi or better) AND that you have good voltage (12.6 or higher) in your battery banks.  Low battery voltage can cause erratic leveling system performance.  If your system passes all the tests, then congratulations - it is fully functional!

The second link is the Leveling System Text Book.  Read this manual if you desire a more in-depth understanding of how your system operates.

Autolevel on my 2001 has never worked in 5 years.  I manually level (push Air/level button once), level the coach, and turn off the key.
