Write-ups will have to wait for a slow day, but I uploaded some photos of some of our summer "projects" today.
The first - our front HWH leveling sixpack manifold. This was the primary cause of our leveling issue for months - at least one, probably both, raise solenoids were leaking through. CSI ForeForums to be conducted on the old solenoids to determine root cause (we suspect valve seat and/or spring problems).

Good to hear you have the source of torment isolated. Are these solenoids rebuildable? I'm assuming the solenoid portion works but the valve body leaks?
Chuck
In theory, the valve should be rebuildable (the solenoids themselves do work fine). The challenge is that HWH does not sell rebuild parts (that we can find) for the valve seat or spring, just the solenoid coil.
I wouldn't put it past Steve to find a source, though, especially since they're over $100 new for the entire assembly.
Michelle
Dang. Where do you guys live? I want to move close to you so when something goes wrong on my coach, Steve can come over and just "fix it." :dance: I'm impressed with his ability (and lot's of others on this forum) to just dive in and solve problems.
The other day my back-up camera had no power. I stared at it for about 15 minutes, and then ever so slowly lifted up on the cover (where the cup holders are) to see if the cover would flip up. It did. After looking at all the wires for another 5 minutes, I finally saw a broken fuse holder and the fuse laying down in a crevice of wires. Hmmm... maybe that's it! I carefully touched the 2 ends of the wires together and the power came on for the camera! Holy COW! I actually fixed something!! Weeeeeee. To me, that was a major accomplishment! HA!
Steve & Kathy ... we proudly represent the "people who do not work on their coach" ... and with good reason. We know our limitations. We are having leveling issues, Michelle, but ours is that the auxiliary compressor comes on about every 2 1/2 hours. VERY annoying. I am certain that we have leaking air at some spot, but Jeff has been all over the underside with enough soapy water that we now blow bubbles as we head down the road. Sooner or later, we will find the leak. Then we will find Steve and whine until he takes pity on us. ;)
Could be those slide bladders leaking .... *runs to hide* :P
But don't rule out those slide bladder valves, left side wall of the compartment (with the pump), those can fail, but generally only if you had need to use them (ask Barry and I how we know), or the step cylinder, or the air regulator stem, or the raise lower o-rings, or ... well just tell Jeff its a way of cleaning the coach one soapy squirt at a time.
