Update, everything is now working. Thanks for all the suggestions. I plan to have the system gone over when I get home. Flushing the hydraulics seems like a good idea especially since so many parts have been replaced and different people doing it. Hopefully no more problems.

I share your frustration. My problem is different but equally as frustrating. Trying to find a good HWH tech in the area is the 1st challenge.

I'm having a plethora of problems with my HWH system. My repair shop said they talked to a HWH tech who told them the solenoid valves where adjustable. Anyone else ever heard of this? The problem I was having was jacks sticking down. Adjusting stopped that, so far, but now they won't stay down. We have to adjust levelers every couple of hours or so.

I was looking for something and came accross my HWH manual. The fluid diagram desribes how it works if you want to know.

1. Shuttle valve. That valve is between the pressure line to the solenoids and the return line from the solenoids. When it has shuttled to one position it sends the fluid under pressure to the manifold that each individual jack solenoid is attached to. As the solenoids are opened for leveling fluid under pressure is routed to each jack forcing it to extend.

When the shuttle valve is in the other position it connects the return line to the tanks with the manifold the individual jack solenoid is attatched to ( same manifold and individual jack solenoids) When you go to store the jacks all of the solenoids are engaged and the hydraulic fluid is returned to the storage tank allowing the springs to pull the jack back into the storage mode.

This is a very simple system. The fact that you had so many problems really makes me think your fluid got contaminated.

Returned MH to the repair shop and they found two leaking hose connections, kept the coach for 3 weeks with jacks down and slides out and said the jacks never changed.
Just Returned home from a short 3 day trip and had no issues with the HWH system. Hope fully most of my problems are over.
My only other question is why did one of the hoses burst at a connection while driving down the road, I have been in touch with Joe Portelli and he seems to be avoiding the question. I could understand the hose bursting if the system was in use i e when sliding the slide in or out or putting the jacks down. But while driving there should not be any pressure on the system.
Has anyone else had a similar problem?
