HWH leveling system
I can't get my HWH to turn on, all fuses checked ok
Forum Discussion
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.
