Vehicle transmission in Park

Parking Brake fully on.

Batteries fully charged.

Start Key in correct accessory position.

Optional key safety lock turned on.

These are all things that I have not done in the past?

I once had a problem with the control panel with the lamps and switch attached. If I pushed down on the panel it would briefly come to life. I removed the cover panel with 4 screws and found the spring contacts between the panel and the circuit board below had lost contact. I stretched the springs slightly and reattached the panel. It's worked ever since.
On another trip I found another fuse hidden in the engine compartment. Good luck.

Lark,
Any kind of idea what kind of motor home, make, model, gas, diesel, etc???? Also, what model of HWH? Different models operate a bit differently and, gas or diesel rigs have an effect on the operation too because of air brake interlock systems.

First off, we need to know which HWH system you have.
When you hit the level button, do you hear the solenoid click? If not, you either don't have voltage to it, or the solenoid/relay is bad.
There should be 2 solenoids - the main solenoid and another that runs the pump. Measure voltage at the positive (small) post on the main solenoid. If you have voltage there and it isn't energizing, the solenoid is bad. If you don't have voltage there, it's probably a fuse or ground problem.
If the solenoid does click, check the large battery cable to ensure it has 12v from the battery.
You can go to HWH's website and download their trouble shooting guide which will walk you through diagnostics.
Also, be sure you have a good ground. Usually there's one grounding post where all the grounds connect. Be sure the connection is tight and making a good ground to the frame. (Incidentally, if you talk to an HWH tech, he will tell you that most problems they have are from bad grounds)
If it's a 625 system, there should be a control box with a clear plastic lid with LED's and several fuses in it. You can check those fuses and see if any are blown.

Could be the control panel is bad. We had the same problem and had it repaired at the factory for the gingerly sum of $22.50. Call the factory as ask for help. You may be able to send your control panel in for testing and repair. A new one will run up to $200.00 of so.

Take the four screws out of the touch pad and lift it up and see if the wire pulled off the connector. That is what happened to mine once and some good folks told me to look at that first. I just crimped the connection and it is good now.

Our 2001 Winnebago Adventurer also had an inline fuse about 1' from the pump motor.
