Webasto TSL 17 Trouble shooting

[Stubop]

I have the TSL17 Hydronic heater on my boat and it sometimes wil quit while the coolant pump keeps running even though the thermostats are calling up for more heat. Does any know what could be causing this?

Thanks for any help.

Well Gord, Thanks for the trouble shooting link. The unit and all of the accesories were properly installed 3 years ago and it works excellent. I have had several incidents of flame out and did a re-start and a couple of double re-starts.

The fuel filter has not been changed and i'm ordering a new one from Shure Marine.

Thank you for your reply.
