I had the same problem. No lights on the HWH keypad. Fuses were ok. Unscrewed the four screws and lifted up the keypad and the power cable had come unplugged. Simply plugged it back in, keypad lit up and it functioned well after that.

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

Thanks, will try and find which HWH I have. Call yesterday for Tec support got on a call list they said it will be two weeks, nice. Will keep trying.

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.

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.

I can't get my HWH to turn on, all fuses checked ok

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.

03 Monaco Windsor diesel it was working fine. I had it out for run came back and it would not dump & nothing lit up, checked the fuses OK

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.
