HWH One jack will not extend

I have one jack that will not extend. The other three seem to work fine. Any ideas? I have not called HWH yet.

I would first check the reservoir to be sure it is full. If the Jack is the last in line there may not be enough fluid left.

I had the same problem about a year ago with my HWH jacks. My problem was in the control box (dont remeber the actual name). The box is a silver in color box that everything plugs into, this is NOT the touch panel. My control box was located under the dash on the drivers side of my coach. I had to pull it out and send it to HWH to be repaired and got it back within a week or two, and if i remember correctly it only cost me somewhere around $150. Hope this helps you. You can also google HWH and dig around and i found some website that explained step-by-step how to test the box to verify that it is bad before you send it in. Sorry i dont remember the site.

If you have not already done so, go to the HWH web site and download the trouble shooting guide and manuals for your system and start trouble shooting from there. I'm sure you've already rechecked all your electrical connections on the individual jack solenoids. A quick thing to do would be to switch connections with an adjacent jack solenoid and see if the problem transfers to the other solenoid.

Depending on the system you have, trouble shooting using the LED lights on the control panel will usually pinpoint the problem.

I agree with Fleetman - download the troubleshooting guide. It will tell you how to look to see what LEDs on the main board are lit. This is not the control panel on the dash, but the board that is usually located adjacent to the pump and reservoir. Ours is under the coach. Winnie used to put it under the hood of some of the gassers, but I don't know about diesels.

There are also fuses on the panel - one of them could be burned out. If you replace it and it immediately blows again, it is likely a solenoid is burned out.
