When I bought my house last year the central heating system would cut off constantly at the boiler
(lockout light would be on)
the setup is
Oil boiler camray 5 65/90
Burner Riello RDB
I had the boiler serviced and it seemed fine to start with, the problem was gone. Then as the weeks go by it starts to lock out once a day now it locks out every hour sometimes more sometimes less
sometimes just pressing the button works and it fires straight up. sometimes i have to press once or twice. sometimes it feels like i have to press the limit reset and then press the lockout button (could be coincidence that works though)
usually after pressing i hear the boiler fire up. sometimes when i press it i hear it whirring then it locks out again (usually works second attempt though)
the service included,
new filter
Nozzle
flex hose
cleaning the baffles
adjusting pressure on expansion vessel
adjusting air oil ratio? i think
If there was anything else i can't remember.
I've kept the pressure at 1.5bar or just above as the pressure does drop very slowly over time (i think one of the pressure regulating cartridges has a little leak on it, will replace that soon)
where do i start looking to diagnose this?
I've tried to be thorough but if any more information is needed let me know.
