HWH jacks not extending but pump runs

[Chuggs]

That sure is a wealth of information. I had a few HWH documents, but this web site sure helps with the troubleshooting process. Thanks for the link.

I’m in need of the link now…

How did you fix yours.

I started out with an issue with the touch pad. I could usually resolve it by unplugging and plugging it back in.

Well…now I am experiencing what you faced. I turn the ignition ON and the pump runs, sporadically. I haven’t had a chance to see if that is because of a control issue or it’s just hitting the high pressure limit…with no open valves to Jack stands.

I am thinking the touch control is bad. But the troubleshooting guide warns that of your MIOM is also bad it could damage a new Touch Control.

I have checked the yellow and green wire resistance, that’s good. But maybe should also check them alone, MIOM isolated, and Touch Panel isolated?

I see LINK lights, but will check again.

I need to check relays for being stuck…

Were of course traveling…so have to order parts to meet us somewhere ahead.

Really just checking to see what resolved your issue. More inout for my brain to process…

Hope this finds you well and your coach in good working order.

The only HWH problem I have actually had was a bad solonoid and that was an easy fix. i was really just appreciative of that link you supplied in case I ran into similar issues -- NEWMAR COACH SPECIFIC INFORMATION – HWH® Corporation
