HWH 625 Levelers
For about a year, I have had a problem with my jacks coming on.
The travel light comes on, I keep pressing the on button and eventually get it to work, I have a you tube video showing the problem, I was told it was probably a ground issue, any one else had list happen

Proper and good electrical grounding is critical on the HWH system. I recommend you locate the pump motor and both solenoids and disconnect, clean, reattach and protect all ground connections - especially the pump motor to chassis frame ground.
I had a problem early on with one of the solenoids on the pump. It was a bad internal ground on one of the pump solenoids. An HWH tech, Randy, walked me through the troubleshooting over the phone. Using a probe to ground the various components, we found the problem.

I had similar problems where several of the buttons on my HWH625 would only function intermittently after many presses. I pull the panel out of the counsel and separated the two control boards. I then sprayed contact cleaner into the switches, dried them out with canned compressed air duster, reassembled everything and, Bobs my Uncle.

Welcome to irv2.
All the links below in my signature have answers for your Newmar.
In QT's 1 & 2 you will find all HWH information and other items in your coach.
All the white wire leads go to a common grounding point on chassis frame or a grounding bolt on frame. The HWH links will have trouble shooting procedures and operations.
Enjoy the forums and safe travels.

Its been several years since I did mine but I don't recall having any trouble separating the control panel and its 2 boards. I don't recall having to "pry" anything apart. The second board is mounted to the first with short bolts and spacers which needs to come of first and I think the the second is mounted to the panel itself with screws.
I didn't take pictures but here is one I found on the internet.

I am also having a problem with my HWH system. Per your advice I contacted Paul by email explaining the problem. Within a couple of hours he emailed back identifying the problem and solution. Thanks for posting his email.
