Hello all. I have a Webasto DBW 2010 with about 6000 total hours. It was rebuilt about 200 hours ago with new motor but not sure what else was done. All worked fine after the rebuild, but now I’m having the following smoking problem:
• Unit starts up and air exits the exhaust
• After about 15 seconds there is a “puff” and unit ignites, starts burning with a small amount of white smoke that seems consistent with past operations
• After about a minute the exhaust noise increases and suddenly there is a copious amount of white smoke belching out the exhaust. And I mean a lot.
• After two minutes of belching things suddenly start clearing up and after another minute no smoke is visible
• The unit runs perfectly with absolutely no smoke for as long as heat is required
• After cycling off (hydronic water is hot enough) for 5 minutes or so the identical process starts all over again as it turns on again
Any thoughts would be appreciated.
