Hi All
First time post, long term reader of these pages and the sound advice often found on these pages.
Got a problem with my webasto thermotop C/E...thinking I've perhaps left it on too long the other night when i forgot about it watching telly. Basically it knocks on fine, starts going through its usual process of ticking away and sounding like a distant jet engine. This goes on for about 10 minutes before it shuts down. When i first noticed i took the fuse out between battery bank and the webasto and gave it a clean and check over. Also unplugged the control panel and reconnected it. Doing these seemed to increase the amount of time it would stay in cycle, but only by about 10 extra minutes before it would shut down again.
I also noticed after my first attempts at fiddling around with the fuse that during the cycling, there would occasionally be puffs of white smoke coming out of the exhaust. The rest of the time the exhaust runs as normal.
Had a similar problem once before which was due to my fuel running low but unless someone has syphoned in the last week it shouldn't be this.
I use the system for both hot water and some radiators but can't tell for certain if there is any warmir going on but the calirifier seems slightly warm.
