Hwh leveling system January 15, 2025, 04:55:50 pm We are the new owners of a 2006 30 ib. Where are the HWH solenoids located. No issues at the moment but would like to know where they are should issues arise
Re: Hwh leveling system Reply #1 – January 15, 2025, 05:28:34 pm Do you have kick down jacks or straight acting jacks? I would recommend trying to ID the jacks cylinders as well as the control panel in your system. There should be sticked on the jack cylinders with model numbers, and it might be slightly different on each of the 4 corners.If they are working properly now, keep using them periodically. Long periods without use if what causes issues.I find that the HWH website has decent technical information if you look hard enough. They haven't been easy to get parts from though. Stuart's Services has been a good resource for me, from calling to ask questions to ordering parts. RV Leveling - Stuarts Service & HWH Leveling System Replacement Parts – RV...Rich
Re: Hwh leveling system Reply #2 – January 15, 2025, 05:36:34 pm Hi Seasidebb; If you have a single, central hydraulic pump, the valve manifold is located at the pump. Solenoid electrical coils activate the valves. Hoses route fluid to and from the cylinders at each corner location. RonB
Re: Hwh leveling system Reply #3 – January 15, 2025, 07:47:23 pm The power pack (the reservoir, pump, manifold, and solenoids) should have a specification plate.You may need to unscrew and remove the control panel to determine the model and its spec number.If you don't have the owner's manual, try to get one. A wiring schematic can be very helpful when troubleshooting.Determine how to raise a ram that refuses to retract, it happens more often than you think. The usual culprit is a solenoid or a wiring problem but the control panels can fail too. Commercial hydraulic solenoids have a way to manually cycle them if the coil burns out. I have never seen this feature on an RV leveler's solenoid.To manually raise most RV levelers requires disconnecting one of the hydraulic lines and pushing the ram up by hand, expect oil to shoot out of the ram and/or the removed line. It gets messy quickly, have a can or something to catch to ejected hydraulic oil.Use bailing wire or zip ties to secure the ram up if it wants to drop.Larry
Re: Hwh leveling system Reply #4 – January 15, 2025, 07:56:18 pm I also have HWH jacks on my Lazy Daze that were already installed when I bought it in 2012. They worked very well for years until suddenly a spring broke. Even so, the kick-down jacks can still be pushed up by hand, although the bending down and pushing up might be beyond my old body now. Anyway when I got the springs replaced and jacks serviced, they recommended replacing both springs, which I did. I'm not as cavalier about using them since, but they are still wonderful with their joystick leveling system.Kristin in Alaska
Re: Hwh leveling system Reply #5 – January 16, 2025, 08:08:10 am I imagine the location could vary depending on who installed them, not always installed at the factory in Iowa. In my 1999 26.5MB the pump and solenoids are located slightly off center (between center and edge) towards the drivers side, and about 1/3 from the front or 2/3 from the back, underneath the vehicle. If your system is working you should be able to hear the pump running when you are using it.
