I parked my coach at a resort, hit the HWH
And it leveled fine. The next afternoon the air pump started running and kept going, I noticed the front was a low and tried to raise manually. Again the air pump ran but didn't raise.

Not sure I can make it home in this condition and have to leave today. Any thoughts?

As I mentioned above, the coach leveled, then as it was "maintaining" the air pump kept running and the front end was way low.

When ready to leave, it did go to travel mode, and when I got home I tried leveling and the front end came up well on it's own.

Question is, what kept it from staying up when parked on the "maintaining" mode, and also kept me from raising manually?

My only experience with that was when an HWH exhaust/vent valve stuck open. When that happened, though, I could hear the air rushing out of the open valve. I joggled the system a number of times and the valve finally closed and all was good again.

Did you start the engine when u tried to raise it.

Sounds like a simple leak and the air pressure was too low to raise.

Have to find the leak of course.

I too think the air exhaust valve at the bottom of the clear plastic bowl was leaking. You will not hear it because the pump is too loud but you can put your finger on the opening to see if you feel pressure.

If this continues then replace the valve, just know it is expensive, options are to thread on a small valve like used for a ice maker under the sink.

I presume my manual shows me where to find the valve/bowl?

We have the same coach.
The Leveling system is in the front drivers side compartment forward the front wheel.
The Bowl is just about 3" tall, clear plastic. The valve is attached to the bottom of the bowl. Sorry for the sideways image.

I added the pressure gauge

If the problem is with the valve under the dryer bowl on the pump then you wouldn't be able to raise any wheel position. If that is the case, check that valve. On my 2000 Magna I could raise other wheel positions but it was a faulty HWH valve for my problem that would not allow me to raise the front right wheel.

Thanks for your help, I'll see how I do. I need to learn about the HWH system. Looking at the panel, I didn't see that you could raise the front wheels independent of each other (basically have 1) raise front 2) raise passenger side 3) raise driver side 4) raise rear
