Hi,
Newbie here so feel free to teach me the etiquette of this place, and apologies for the lengthy opening post.
The boiler started locking out on Friday after a long period of faultless running, there was a bit of gunk on the back of the (newish) nozzle (Danfoss Nozzle 0.65 x 80 EH) , cleaned it with carb cleaner and blew it dry. Popped the cover off the pump (Danfoss BFP 11 L3) to check the filter and woah, full (and I mean full) of c**p, cleaned it all out including the channels by the pump gears, oil feed tube, bleed port etc.
Bled it up, fired it up off the boiler and bingo, sparks, little flame, then solenoid opened and whoosh - nice flame.
Patted myself on the back, fitted the burner to the boiler, set the pressure to 7 Bar, happy wife happy life.
It ran fine yesterday morning and night, then this morning it locked out again and when I took the burner out it still has good sparks, the little flame, then the solenoid opens and it gushes oil out of the nozzle but doesn't fire. Blast tube is dripping with oil after one try.
You can't take anything for granted with this boiler, it was "serviced" by the previous owner's son in law, and I have no faith he did anything useful (missing screws, stripped threads, filthy filter in the pump and no other filter in the line, or a stop tap, fire valve, non return valve (top of tank is below the bottom of the burner). These issues will be fixed asap.
Any ideas how to proceed until I can get a grown up out to service it?
Cheers,
Nick
