HWH Hydraulic?

I have the HWH Hydraulic system with the dump button. I purchased the motor home from a friend whos dad died. He said to use the dump button before placing the levelers. Do I hold the dump button until I hear no more air escaping?

He does not know a lot about it.

Thanks so much,

Brian

It would help if we know what year and type of motor home you have. This link has the owner manuals of several different versions.

With my coach, I just push the level button twice, no need to use the dump button

On the '02 Dutch Star w/HWH system I held the button down till I didn't hear any more air escaping, then used the jacks to level.

Well Sir,
You just stated your coach but, not what HWH system you have. You see, there are a few different models. In our coach, an '04 Itasca Horizon 36GD with the C-7 330HP CAT, it came with the HWH 625 Computer Controlled Automatic Leveling System. Now, in the owners manual for the coach, and the operational manual for HWH on that particular system, it states:

1. Set parking brake
2. Shut down engine
3. Turn key to ACC
4. Turn on HWH leveling system with one push on the power button.
5. Push the power button again and,
at that time, the system automatically depletes the air bags. It will deplete them for approximately 20-25 seconds which, is basically close to completely empty.
At that time, it will begin extending the appropriate jacks, based on which side/end is showing the yellow lights on the key pad. Once the low end is up, then it raises the low side. At that point, it will descend the last jack and, once it hits the ground, it raises the coach approximately 3/4" and, at that time, the entire system shuts down.

That is for the Automatic operation side of the 625 system. In one part of the ops manual for the HWH, it does say to "Hold" the power button for the complete dumping of the bags. But, I've never had to hold that button. I just hit is a second time, after turning the system on, and, the HWH system just takes over the operation.

For the manual operation:
1. Set parking Brake
2. Shut down engine
3. Turn on HWH system
4. Push "Dump" button on key board.

At that time, it will dump the air out of the bags but, that's all it will do. For leveling, you then start pushing the appropriate down arrows for the low end or side. After that, it's up to you to get it level.
Scott

Have you tried Auto-Level?
My HWH system will dump the air bags, and then after a short delay, it will start lowering the jacks to level.

Thanks Fire Up, I have the 325 series with Dump button. I think mine is like the manual series that you hold the Dump button. I just was not sure if I was supposed to hold it until I did not hear anymore air leaving the air bags.

Ours, like many others dumps air automatically when auto leveling. However, if you want to use jack pads you will probably notice the coach moves slightly as the air is dumped. So if I choose to use jack pads I will manually dump air, place the pads and then auto level.

I have the same system and that is the correct procedure. Then I drop my rear jacks first just until they touch the ground then drop the front. I try to level with the front jacks. Most campground sites slope down back to front.
When you hit the store button the jacks retract and the air suspension begins to inflate at the same time. Another tip is never move your coach until the air dryer purges. That way you know your air springs are fully inflated and air tanks are full.

Coaches with HWH Kick Down Jacks, put jacks into vertical position before dumping air bags.

That's how our present Magna is too, in fact it doesn't even have jacks, just the suspension air bags.
