HWH leveling problem

When auto leveling the HWH on my 2014 MADP it worked fine for a few times....after trying to level on a difficult site, front to back and picking the front wheels off the ground, when I try to auto level it now, it raises the front end much higher than the back, requiring me to manually adjust the front end back down to level....can anyone tell me where the HWH control board is located, and any info concerning its adjustments....thanks

Here's a link to some previous threads re calibrating HWH jacks.

if it has a potted control box mounted on top of the pump, (725) system. the level sensor is mounted seperately and remotely. you will have to ask the manufacturer for the location. hwh does not determine the location. if you are fully extended. you may be into excess slope, but that should have already been indicated on the touch pad.

Welcome to the forum & irv2.

The level sensor should not have changed anything its just to show coach when level.
The sensor will be approximately at mid coach.
This link will give some direction as to installing a new sensor and how to adjust.
Unless a rock or something else hit it the sensor should not cause your problem
There is a other leveling sensor on a DP coach in compartment under drivers seat that you may have and I will have to find it if its not in the link provided.
Here is the leveling type you may have its in same thread.
In my signature below are QT's links that will cover many items in your Newmar.

I love my HWI leveling system after two Power Gear, but my HWI seems to always level high when not necessary. If it is a little out it does great. When there is a little more slope I level manual.

Good info here on HWH leveler problems. I just got home after a long trip during which one of my jacks had to be manually retracted. I'll do the trouble shoot process, but as I was doing some work with a farm tractor I had to admit that the hydraulic cylinders on a fifty year old tractor ( one not much larger than the HWH jacks and single action) had been through all kinds of weather and grunge with little attention paid to them and still they function as designed. Hard not to agree with an earlier poster and wonder at the quality of the materials or the design.
Not sure if HWH rebuilds the jack cylinders but it seems they should. I got good service from them when I replaced the retraction springs and will see on the cylinders.
