HWH Excess Slope

October 07, 2017, 08:05:21 pm

My excess slope light never comes on and the coach is still out of level. Just wondering if I'm not letting it go long enough. Has anyone ever experienced this? Have you ever let it go long enough for the light to come on? Just wondering.

mine will come on if it cant auto level itself after 10 or 15 minutes. Not sure if that is long enough or too long? $:-\$

It will come on if the coach tries for some period of time and can't satisfy the level sensor.

If your "Excess slope" light doesn't come on yet the coach isn't level, then perhaps you need to adjust the sensor.

What lights are showing on the touch panel when the coach is out of level? If you don't have one or two yellow lights showing, then the HWH brain thinks the coach is level. The excess slope light will only come on if yellow lights are showing, and the system cannot turn them off by either releasing air or adding air to the bags.

If the HWH system thinks the coach is level, and it is not level, then like Michelle said you need to adjust your level sensor:

I have out of level lights when running. I just never let it go for a long time. Usually after a few minutes of waiting I will manually check the level manually with a level to make sure we are not way off. If we are way off we find a new spot.

Does anyone carry leveling blocks? What do you recommend for these Heavy coaches.

Can you tell if it's actively continuing to try and level while you're letting it autolevel (air exhausting, corners/sides lowering or raising)?

Have you ever tried letting it finish to see if it does throw an "excess slope" light? Might start there and see if it completes leveling successfully, is unlevel with no excess slope light (level sensor needs tweaking), or does shut off unlevel with the excess slope light.

John,

You should not need leveling blocks except in extreme parking situations. If your HWH system is functioning correctly, it should be able to keep the coach level when parked.

If you park, have the system in "auto level" mode, and yellow lights are showing, then the (600 Series) system should react as follows:

1. First, it should try letting air out of some of the bags. If this doesn't work, after 2 minutes it will go to step 2.

2. Next, it will try adding air to some of the bags. If this does not turn off the yellow lights, after 15 minutes the "excess slope" light will come on.

3. When the "excess slope" light is on, the HWH system has done all it can. That is the time to either move or use leveling blocks.

If your system is not following this sequence of events, then trouble shooting is required. Do you have the HWH 600 Series Owner Manual?

Not only will the excess slope light come on, but the aux pump will also shut itself off. I always let mine run until it shuts off, then I'd consider another spot, but you have to let the leveling system do it's complete thing first.

May not be needed, but you certainly loose nothing by getting the coach closer to level before activating the leveling system, whether jacks or air leveling.

And to answer another question, I have always carried leveling blocks (homemade). One sheet (4'X8') of 3/4" marine plywood cut into strips wide enough to support entire front tires plus 6" extra in both length and width and both rear tires plus 6" then screwed together and oil base painted/varnished (whichever I have left over from other projects) lasts for many many years. They can be placed under tires (drive up on them) or if jacks, placed under the jacks themselves.

Chuck,
Everything is working fine as you described. I allow the system to automatically do it's thing. I just never have let it go for 15 minutes like you have described. Was afraid to let it go that long. My driveway at my summer location has an incline on the blacktop. Maybe if I let it go for 15 minutes it would level out. When I usually decide to turn it off I would check it with a level on the floor the bubble would be between the the lines with the bubble just slightly over the line one the low side. I will let it go longer and see what happens. Either way it's close enough for the fridge to run properly.
Thanks you all for your help and info,
John M.

Well I let the HWH do it's thing till it was ready to give up. The excess slope did come on. The site is still close to level. Within the line on a level. Thanks for giving me the idea to let it run and do it's thing.

John,

Just curious - what yellow lights are showing when the excess slope comes on? Also, what are the condition of your air bags? Are the front bags completely deflated and the rear bags fully extended, or vice versa? Do you have any air pressure in your tanks, or is the aux pump supplying all the pressure to do the "lifting" work?

Chuck,
The bags are in great condition. I usually back in my drive. The front end is low with the yellow light on and the system extends the front end all the way up in it's attempt to level. It was just me being to chicken to let it run for the 10-15 minutes till it exhausted itself. It's working fine and doing it's thing. I do have a slight leak in the rear but nothing serious. I will be looking for Thea and working on the six pack when I arrive in Florida. Now I know my bags won't blow up when leveling from too much pressure 😂. I guess I'll make some leveling pads to carry with me for those out of level spots. I have a sample picture that Don & Tys posted on the forum.
Thanks again,
John M

Not that it pertains to this particular post but I leave our motor on high idle when leveling IF there will be an UP command that is needed.

Much faster than the 12 volt thomas pump under the coach

Bob,
I agree! I usually level with the motor running at campgrounds also. It does work faster.

When it does that, the distance from the last step down to the ground can sure catch you by surprise! Been there - done that!

Chuck,
I agree. I might have to invest on an adjustable safety step for those very tall days. Especially if we are having a good old time with friends and drinking a few. 😎

Most everyplace we park is an "extreme parking situation".

I do basically the same as Don. Lots of 2x10s. I don't have mine screwed together. I just pull out as many as I need and stack em' up. Do be careful to get the full tire on the board.

see ya

While solid wood will work, they are much more susceptible to cracking than if you cut plywood and then screw pieces together.

One 4X8 sheet of plywood cut into pieces (size somewhat dependent on your tire size (correct width for a 9R would be too narrow for a 295, for example) should certainly cover your leveling issues.

I was using wood switched to those "Leggo" things they seem to work well 90%of the time. A bit lighter then wood.

I carry 4 4x12's about 18" long with an angle cut on the end. If that doesn't get it then it's time to move. Like Ken said we use them about every other place we stay.
