One leveling jack not holding

[davidw2262]

The right front jack on our 2009 Phaeton HWH leveling system is not holding/staying down. Initially auto level works but front right jack does not remain down.
Any ideas? Thanks

Fluid level for the jacks?

Cycle them several times but it sounds like a solenoid leak.

cobra has it right.
just make sure you get the right solenoid replaced.. go out and mark the jack cylinders with an ink marker. mark it a couple of spots about a half inch apart on the silver shaft.
check them the next day at the same time. that will tell you which one is leaking up.
if an opposing jack leaks down, it can cause the coach to pivot and move the other opposing jack off the ground.

Yep, just went through this exercise with our LH. The left front jack was losing position in about 1/8" increments until there would be no weight left on it.

Typically, Tiffin used two different solenoids in their hydraulic systems. Smaller ones for the slides, and larger ones for the jacks. Go to HWH website and download the Owner's manual and Service manual. They will show you which solenoid is affiliated with a particular jack and will give you the part number for that solenoid.

You can purchase the solenoid at most any major rv service centers and be prepared to spend close to $400 bucks for the larger solenoid.

Installation is actually very simple, but it depends upon where your hydraulic pump/motor/manifold/tank is located. Mine was positioned in a very awkward place and made the installation unnecessarily difficult. Be careful of the wires (you can disconnect) and also make sure that when you put the solenoid in, that you don't crimp any of the four O-rings. A large channel lock pliers will do the trick.

Good luck

Nope, actually it was around $325, but I checked other places and all the others were more.....that's why I said close to $400. I didn't check eBay, but I did Amazon, Camping World, and a couple of other rv websites. I finally got mine from Guaranty RV in Junction City Oregon. I also checked on the price of the smaller ones, and it ran about $175.
