We're having an odd leveling problem that HWH believes is the level sensor - on a perfectly level site our coach will noodle exhausting air and settle almost every hour.  Each time here at Camp FT where the back end is squatted and the front up pretty high, it's been perfectly content.  We have other symptoms such as too long a response to out-of-level situation and the coach taking itself out of level.  We have a new sensor on order, but since we have the same coach as [Barry, with the leaking tag air bag] you it got me thinking.

Well, nothing around the air bags bubbling with the soapy water.  We hit them with a spray bottle as best we could, not having blocks with us to get under the coach safely.

I thought for sure we'd find a leaking tag air bag like Barry has.  It certainly seemed possible since the coach was very happy with the back down - not once while in the unlevel site at Camp FT did it adjust itself.  And in a level situation it eventually got itself so bizarrely out of level that the front slide came in biased to the rear of the opening (the second time this has happened).

Steve thinks maybe a check valve isn't "checking" and letting air move from the back to the front OR filling one of the front air bags when it's not supposed to.    The new sensor should be here any day now, so we'll see what that does, but we're not entirely convinced that's the only problem.  It's a pain to diagnose since most of it is just letting the coach sit for hours while you observe its behavior.

Well the new level sensor didn't solve our problem.  Coach sunk behind, raised up in front, and Steve reports an "Excess Slope" light once again. 

On a positive note, initial leveling is much snappier and responsive with the new sensor board.

I know that the excess slope light comes on after approximately 30 minutes of trying to level the coach (extinguish a yellow light).  At that point it just shuts off and a new leveling cycle has to initiated (you probably know that too). 

Sounds like you have a solenoid in one for the HWH manifolds leaking by when in the level mode. Do you have all the manuals on the leveling system? If not you can down load them from HWH for free. Its fairly easy to follow the manual to diagnose the issue, just getting to the f&r manifolds is a pain. Also be aware the system will only Level 4" front to rear and side to side. My bet is one of the travel solenoid's is leaking internally. Remember to block you suspension before working on the air leveling.

James told me that HWH has some separate manuals for Foretravel. You probably already knew that. Here is the link he sent me HWH Operators Manuals for Foretravel.
You may also have HWH's textbook on air leveling systems, but I have attached it anyway. It's dated in '99, but may be of some help to someone. Disregard my highlighting.
Please keep us posted as you progress on this.

It's interesting that we noticed we're hearing air exhausting at the rear of the coach even when it's just the front being intentionally lowered.  Also, the intentional lowering has a discrete on/off of airflow noise.  The rear has a very long duration, gradual sound decrease reminiscent of a dumping the air (as if a valve doesn't close).

Could you just hit the "HWH Reset" button to turn off the auto leveling?  Just a thought.

That's pretty much what we've been thinking, a solenoid that's not closing properly.    We've noticed the issue most frequently (possible always) occurs when the coach has both a low side and low rear.  It will get the side to side ok, but then when it switches to raise the rear, that's when the front starts coming up, too.

Hmmm...sounds like the usual technician's approach to repairs...hit the easy and they don't know where else to look for a solution.

If I may suggest, this summer when you are in your travels, schedule an appointment at the HWH factory in Moscow Iowa if you want this problem fixed. 

Have you tried just turning off the system after the coach is level?  If it then becomes unlevel after a set time period like 24 hrs, then there must be an air leak. 

I have worked with HWH by phone several times. Getting to talk to someone can be frustrating but once I got to a real person, they have been extremely helpful and accommodating. I was told in one phone conversation that there had been so many layoffs that most of the remaining people are doing three jobs compared to before the recession. If you leave your phone number, they will call you back one time. They will not leave a message. If they can't get you on the phone in that call, they move on to the next customer until you call back.

If you make an appointment so that they can schedule their time I think you will find you will get competent work. On the other hand, my dealings with them was over a year ago. Things may have gotten worse by now.

Steve & Michelle,
My understanding of how HWH works:

Top two valves of 6-pack are closed when ignition is off and open when ignition is on. Closed top valves keep ride-height valves from controlling air bags. If top valve O-rings are leaking, letting air flow from ride-height valve to air bags when top valve should be closed tight, soap leak test would not see this as there is no air leaking to the atmosphere. And if you are on level ground, the ride-height valves are closed, so all looks good.

You said "Clearly the front raised overnight": Front ride-height valve is always trying to raise whenever coach is low in front, whether ignition on or off, engine running or not. Leaking front top 6-pack valves will raise front air bags to travel position, changing level system setting.

But it also seems that if level system is on, it would wake up and try to re-level coach by dumping air.

Steve's going to look at a few more things himself; might even consider a call over to Buddy Gregg in Lewisville since they should have experience with the air leveling on Monaco and Country Coach.
