Air leveling problem!

[MSHappyCampers]

Our 2002 Windsor uses air leveling only, no jacks. I normally pull into a site, extend the slides, dump the air to put the step close to the ground, and then auto level.

I've noticed that if the rear of the coach is showing low on the HWH display that sometimes the system will not raise the rear enough to be level. Yesterday I was messing around with it and discovered that if I do the auto level without dumping the air then it levels just fine.

Have any of you with air leveling only run into this problem?

Hi Joe, I have an 03 Windsor, I'm sure our HWH is the same.
As I recall if I still have enough air in the tanks mine will raise
the coach but if the air is depleted I don't think my 12v pump
will do the job. If it would it might take forever.

Did you still have air, or was it using the pump?

Mine will not raise the rear enough to level, even with the main tank at 120 PSI.

Sorry Joe, but I don't have the HWH system. Mine is a Valid air level only. With the valid system, the system can re-learn what is level by doing something called a 'zero set' from the manual. I'm wondering if HWH has something similar?

I know Monacoers has the HWH service and operating manual in their download files. Did you check there?

Bill, that's not the problem. I have checked the actual level with a long carpenter's level and the system is accurate. It just won't raise the rear enough when the air is dumped and the rear is low.

Hi Joe; This is the experience I had with my previous 2000 Windsor that had the HWH air leveling. First, I never did dump my air and level. I did notice in almost all my leveling situations, I almost always seem to be in a fairly level spot ,that the system always seemed to be letting air out of the system to level than to add air to a certain side or from front to rear. To me it makes sense as that would be the quickest way to level. Not sure on the how the proper sequence of the system is designed. Let air out of the high spots and then add air to the low. I'm not sure. Does the HWH manual cover any of this?

Don't know. I'm got to read the manual.

In my 04 I am having similar issues. Picked it up August 2020 the rear would sink over a couple of days. Now it falls in less than a day. Believe I have 3 issues. First is the air leaks. Second is the park brake switch. I think that is causing the air level system to not work when parked. Last is the how does it fill. I am not sure but i think the ride leveling valves are not the same as the level leveling valves. May be the same but different ones operate different things at different times. This could be your issue as to why it wont level up with air on the button. My issue with the park brake switch, doesn't let me use the air level buttons, except for raise and lower when in travel..

Hello Joe, I auto level with full air pressure.

I do not dump the air.

I also do not have the onboard compressor.

Just what I have been doing and it seems to work till the leaks catch up with me.

Do you mean the aux compressor that keeps the coach level even though the main air tank is low?

You should be able to raise and lower the rear alone by itself. If you hold the up or down arrows do you get any response?

When the rear is showing low I can press the rear up arrow but it won't raise it enough to level. I suspect that the air manifold in the rear may have a problem!

Hi Joe

On our HWH air leveling only 2000 Windsor, I mostly use manual leveling mode. Even if I start with automatic, I end up fine tuning it manually.

There is a sound indicator for the highest level which is very useful. When raising front or rear of the coach, if air tanks does not have enough pressure, small air pump kicks in and I can hear it running. When the highest point is reached, pump stops and I hear a small knock noise and then when I release the up button, I can hear a short air release sound coming from solenoids. I am not sure where that small knock sound is coming from but it is very useful to tell the highest point is reached for that pair of airbags.

Do you have those small air leveling pumps in your motorhome, and hear the same sound when highest point is reached?

Maybe it's time to reseal your six pack valves?
