Hydro-Hot Acting Strange

Yahoo Message Number: 78840
Sorry if this post is a duplicate but it's been 1/2 hour since I posted this the last time and it still has not appeared in the forum.
When I got up this morning the coach was cooler than it should have been. I checked the HH diesel switch and the light was off. I turned it off and back on and the burner fired up but there was a lot of smoke. The burner worked all morning and no smoke.
Late in the morning I noticed the light was off again. I went outside and checked the control panel and all the appropriate lights were green. I toggled the switch, the light came back on, the burner fired up, and the white smoke appeared. The burner shut off after a short run, I checked all the lights and all showed good. I turned off the diesel as it is warm enough now to run the heat pump.
The unit was serviced by Chris Snyder in December, 2011 but we had a guest staying in the coach during Jan - Mar, 2012 and they never turned the diesel off. Could it be that I just need to get it serviced again? if so, does anyone know a competent HH technician in the Seattle area? I'd try to fix it myself but I am still working full-time and have other issues o deal with like a leak around my satellite dish.

Thanks,

Bob

First, I had Chris Snyder do the annual Hydro-Hot service in December. We had guests staying in the coach from Jan 1 to the end of March and they never shut off the diesel burner but the electric was on.
Today I woke up and the coach was cool (it's 40 degrees here in Seattle) and the light on the diesel switch was off. Since I had not had my first cup of coffee, I just turned the switch off and back on and the burner fired up. However there was a lot of white smoke. The burner worked fine all morning with no smoke. A few minutes ago I noticed the burner motor was in its cool-down stage but the light was off again. I went outside and looked at the electronics panel and all appropriate lights were green. I turned the switch off and back on again and got more white smoke.

Ideas?

Check your fuel lines, your getting air into the system. I had to have both fuel lines replaced to the Hydro hot.

Bob: I work on mine so I don't know a technician, but Roger Berke's forum is a great resource. It could be something very simple like a flow switch or you might even check for low fluid; if the fluid was low, you would get the light on the panel however. Sorry I couldn't be more help,

Follow-up to my problem. After acting up that one day the problem has not returned. I scheduled a check by the local tech and we watched the HH run perfectly for an hour and decided not to mess with it. It's been running a lot since then with the temps near 50 all day and no hicccups. Of course, maybe Murphy figured that with a tech only 100 yards away (they stay in the same park as us) it wouldn't cause enough trouble to fail again :-)
