I'm sure this has been asked several times but I couldn't find it so here goes: I'm stuck in a safe place with shore power but my HWH brand system has no lights on the leveler touchpad (jacks are down) and neither slide will retract. The parking brake is set and it is in park. The " jack's down" light or buzzer does not come on. I have checked all of the fuses I can find. The manual suggested checking the Radio/account and Step alarm fuses, but they were good too! The HWH control box under the hood does have indicator lights on and I can jump the pump solenoid and make it run. The HWH manual shows a 5A fuse near the buzzer but I cant find one. I called HWH but they are busy for another week or so and will get back to me ...

Anyone bump up against this one before?
Thanks 🤠

Since you have confirmed basic power at the control box, try gently removing the touchpad (4 screws in corners if like mine) and checking to see if the control cable on the back side has come loose. The pad should be lighting, so it's possible it's not "talking" to the control box.

On my unit, the key has to be turned to the start, but not started position, parking break on, and transmission in neutral. On your unit it has a park. Not sure what your manual states for extend and retract, but hopefully it is a simple procedural thing to fix. I doubt one 5 amp fuse controls both the jacks and slides. If it’s a fuse issue, suspect a much larger or multiple ones. Best wishes in resolving your issues.

Did that and the 5 wire connector is secure. Also checked and the red has constant power and the white is ground.
Dang 🤠

My advice is to contact Paul Maddox, aka azpete on IRV2. He's an IRV2 member who works for HWH. He can be contacted via PM or, better yet, via pfmaddox@att.net or at 602-549-3638. He publishes these regularly on IRV2 so I wouldn't be reluctant to call him. He's helped out a lot of us on IRV2 and Winnieowners.com.

Just had a similar problem with my 2004 Adventurer, turned out that the main solenoid that powers the pump wasn’t getting a ground signal from the park brake. I put a jumper wire to the frame and everything works, but I’m still trying to track down the problem.

I have to ask ; does your control pad light up ?

Only with the jumper connected

Good comment. My parking brake seems to make connection ok. The dash indicator goes on/off and when shorted to frame it does light.
I'm still checking 🤠

A little late, but...

KennR1 - Did you get this fixed? I'm in the middle of a trip and both our HWH 625 Touchpad as well as the Control Panel have no power; I cannot seem to find the darn main power source/fuse.

FYI, 2008 Ford E450, Aspect 26A.

Where did you see the comment about the radio/account fuse? And what is the "account"? Will check those tomorrow. but I do not see the connection between radio/leveling system?

Pago Cruiser:
Yes got it working. Note that my unit is an 04 Itasca on a Workhorse chassis so my notes are generalized to you.
First note there were NO indicator lights on in the control box (under the hood).
From a mobile mechanic: some power comes from two fuses under the dash. One is labeled Radio and the other is Acc (Accessories) Mine were good.
What did make a difference was the old "turn it ALL the way off, let it set for a while and turn it back on". I disconnected all of the batteries overnight and reconnected the next day it worked.
Hope one of these work for you!

Kennr1,

Thanks for the reply.
As you can tell, I am kind of grasping for potential solutions...
Haven't yet tried that, but I guess I can later.
After an hour on the phone with a very gracious WB tech yesterday, at least I now have some connectors identified that are supposed to have power - and they don't.

Regards,

Mitch
