Welcome to the forum. Why don't you go ahead and post the model number of the HWH system.

Make sure there are no leaks in the line going to the jack. If air got into the jack or lines it wont work. Exercise the system a lot to work the air out. HWH probably has some manuals and diagrams on your system.

Good Luck.

When a jack is stuck, I was told to hit it with a 2 x 4. May work

download a service manual for your system from the hwh website. locate the diagram that shows the location for that cylinders solenoid. check the black wire for 12 volts. if it has 12 volts, open the solenoid and push the extend button. if it goes down and right back up, re-place the solenoid. if there is no 12 volts, check the fuse in the control box. if its blown, replace it and try again. if it blows, replace the solenoid. its shorted.
if not, then the control box is an issue. as you can see, if you dont do the diagnosis, it can get expensive.
let me know if i can help. i do work for hwh. i do diagnostics, i do not sell parts or solicit service on this forum

Malfunction HWH Jacks

Just went through this with my 2000 Damon Daybreak. I have the joystick controls. The cure was to remove the cover over the controls, vacuum out the dirt. clean the contact ring, replace cover and work the controls.
Find the solenoid, clean the electrical contacts and coat with dielectric grease. Lube pivots on the jacks. Clean and lube jack legs. Operate the system.

In the event a jack does not deploy, use a long stick or pry-bar to lower the jack while someone operates the system.

Try this before tearing in to parts replace. Do look for obvious leaks etc.

There is at least one video on you tube.

Have you tried to operate the jacks in the manual mode? If you do listen for the pump motor. If you don't hear it you most likely have a bad solenoid. If you do hear the pump running you will have to dig into it a bit more.
