HWH 625 Leveling System in a Newmar DSDP 3815
Posting this for information in case someone else runs into a similar situation.
My 2005 Dutchstar has a tick over 18K on the clock. Pulled into the Clark County Shooting Range RV park after leaving Death Valley. Went to turn the control head on and nothing happened other than the Travel Mode green light being on. Cycled the ignition key on/off to Accesory, nothing changed.
I tapped the Jacks Retract button and the light for that button came on, the Hyd/Level red light cane on, as did my yellow lights indicating the low points. From there I still couldn't make the system auto or manual level, or dump air. I also pulled the cable off the back of the control head and cleaned the connectors.
A few more on/off ignition cycles and once I was able to get the red Hyd/Level light to come on, but nothing else happened.
I tried the HWH troubleshooting steps but they didn't seem to cover this intermittent activity.
Having seen Paul Maddox' number, 1-602-549-3638, listed in other postings here in IRV2. I called him and when we connected Paul recommended I check for a loose ground. He first recommended the two 9/16 bolts holding the pump to the RV chassis be tightened. They're on the bottom of the pump. HWH did not use a grounding strap instead opting for the ground connection to be made where the pump sits on the frame. Secondly, there is a small bundle of ground (white) wires attached to a stud on the side of the pump housing which he recommended be cleaned and re-tightened.
Well, those 2 chassis mounting bolts were not tight. Snugged them up. Then I took care of the ground wire connections. They were tight.
Turnt everything back on and whammo it all worked perfectly.
I can't thank Paul enough for taking time out of his day to help me and not want any pay. His name is plastered all over this forum.
Thank you Paul!
