Why does one HWH Jack not go down?
That bolt is for the pressure switch on AUTO level HWH systems. NOT used and is just a PLUG. I have NEVER seen a Jack (HWH) NOT fully extend for any type defect. There is 3000 psi of pressure on the system. AT the solenoid for THAT stuck jack, crack the line nut open and see if the jack retracts (fluid will squirt out).
Why does the passenger side Jack not go down?
Well, I worked on the system over the weekend and the result is that 3 of the jacks (both rear jacks and the driver side front jack) all extend and completely retract as they should. The passenger side front jack is still the problem. In cycling the system several times, the passenger side jack has come down about 3 inches. However, that is it.
What should I do if my hydraulic jacks are not working?
It may even be as simple as a blown fuse. However, if you hear the jacks attempting to operate but nothing is happening, it’s likely a more complicated mechanical issue. Attempt to operate the jacks independently to see whether you have a problem with the whole system or whether it is limited to the front jacks or rear jacks.
Why is my HWH leveling system Jack not retracting?
All the information you need can be found on their web site. My first guess would be the corresponding solenoid is stuck in a slightly open position, or not closing all the way. However, the first thing I would do is with the jacks down is to spray the seal on the jacks with WD-40.

Are there any problems with HWH leveling jacks?
The only trouble I’ve ever had with our HWH jacks is the all too common slow-to-retract (or won’t fully retract) problem that plagues a lot of RV owners.
What to do if your leveling jack wont extend?
To help you troubleshoot the situation and find the right solution, RVing expert Dave Solberg teaches you how to diagnose a faulty leveling jack system. You’ll learn what to do to safely inspect your fluid reservoir and valves, and discover the most common reason RV jacks won’t extend.
What happens when all 4 HWH Jacks extend?
If all 4 jacks extend (including the one that did not extend before), then either that jack solenoid is bad or there is NO 12 volt power to THAT solenoid when power is applied. When doing this test, all jacks will extend as long as the pump is running, when the pump syops all 4 jacks will then retract 4.
Can you drive a RV with the Jacks down?
You cannot move or drive the RV with the jacks down, so you have to get this fixed right away. You will likely be under a time crunch as someone else may be scheduled to camp in that same spot later in the day. First, if you are scheduled to check out that day, you should notify the campground office of your issue.
What to do if one HWH Jack does not go down?
IF a jack does NOT extend, open up all 4 T handle releases at the jack solenoids at the pump. Operate the pump. If all 4 jacks extend (including the one that did not extend before), then either that jack solenoid is bad or there is NO 12 volt power to THAT solenoid when power is applied.
