Eberspacher/Espar/Webasto Field Servicing

My Eberspacher D10 furnace has given me pretty good service. It works for 18 months to two years without problems, then starts getting hard to start, and finally refuses to start, at which point I have to call for professional service.

It went out on the very night of the first passage of my Scandinavian cruise this year. What happened was I accidentally pushed the "start" button while we were at sea at night, but the heating system (a different switch) was "off", so the furnace idled all night with no load as the fan coils were not running. After that, it carboned up really good and wouldn't start at all.

I tried to find someone to service it through the entire Baltic, and oddly could not. It got to be a running joke as I would look in every port and fail to find anyone.

After that experience, I decided that I need to develop some ability to service it myself; at least, to get it running. I bought the computer interface which allows you to program it, and reset the lock out. I also bought a complete, brand new spare furnace on Fleabay (a heavy truck take-off; cheap). It was much cheaper than a few spare parts would have been (the parts are hellaciously expensive).

Is there anyone on here who services these himself?

What is needed to get them running again after getting carboned up after an incident such as the one I went through? What causes them to stop running? Is it the glow pin which gets coated with carbon? Or what? So in a pinch can you simply swap out the glow pin? Or do you need to decarbonize the whole thing?

I will be happy for any tips.
