Hello,my brother has a standard sized condensing oil boiler. He has over half a tank of oil but for some reason boiler cut out and when red reset button is hit it doesn't fire. It sounds like no oil but oil there,what else could this be? I'm going to have a look at it shortly and try to bleed it but just looking bit of advice before I go,thanks!!!
 
Lots of things to check here mate.
After reset, is fan running?
To over heat, is pump runing?
Has water got into oil?
Is oil filter blocked?
Has safety valve shut down, which feeds the oil?
Have you turned the stats up, i.e calling for heat?
What are you hearing when it first starts its sequence?
Just shouting aloud to throw some ideas mate!
 
Thanks tipintim. I had him check pump,stat,fan earlier and seem to be fine. I'll check rest later...
Thanks again
 
We need to know what the sequence of the burner is before it goes to lockout. There is a posibility that the remote fire valve has tripped out but we ned to know more info, what boiler it is and how old, could be solenoid etc
 
When was it last serviced? Could be a simple matter of being blocked up.
