According to my Operating Instructions, that's "Flame detector interruption or flame detector short-circuit" so it seems like a fault in the flame detector. more than that, I can't say.

Mine too...

I may have the same problem (2 slow and 5 fast flashes)...changed Webasto OEM online fuel filter (25 EUR!),worked fine ...and then after a few days problem returned...
Fuel pump workes well (ticking)but no ignition even after 4-5 on/offs...
The location of the heater unit is so bad that it's almost impossiable to get there and take it apart to see what's wrong.
Grrrrrrr.
Well it's Spring time...
Any ideas?
TIA
