HWH Leveling System, Advise Needed Please.

Today I pulled our Allegro Bus out of the barn and washed it, along with that I power washed the leveling springs to clean them before lubrication. I then attempted to extend the cylinders in order to clean/inspect and lubricate, however, the only thing that happened when I pushed the air down button is all the indicator lights lit on the box. I tried turning all power off, key on accessory and ignition positions, nothing changed. The "off" button does turn all the lights back off.

The mechanism worked fine in April, I'm wondering if the water created a problem at a sensor. It never crossed my mind while spraying them down as those are exposed under the vehicle and subject to the elements. It's back in the barn now so by morning everything should be dry.

  • ~usermanual, first to your question. It was recommended to me (on this forum I believe) to clean and lubricate the springs and cylinders due to the front two not fully retracting. Do this prior to replacing springs.

    ~Lonny, I'll check that out tomorrow. I do know where the panel is for the system, Tiffin mounted it on the firewall above the pump. The control box has some power supply as every light on it is lit. Perhaps that is why it is not fully functioning, the other components not signaling back.
  • What year is the Allegro Bus? We don't have an Allegro Bus but there is usually a fuse near the pump. Found this on another post: "This may or may not help, but on my 2012 Phaeton there are 3 fuses visible around the HWH pump. As you look at the pump motor from the end, there is a relay on each side. The relays are connected by a heavy (probably #2 or #4) wire. The 40A fuse is on a wire that is connected to the same terminal as the large wire on one of the relays. The fuse is only about 6 inches from the terminal. I missed it at first because it was tucked under the pump.The other 2 fuses are 15A."

    why would the springs need cleaning and lubricating? the only sensors are the jack down ones they get wet driving in the rain I would assume?
