Hi all
Last year & inherited a C/H system with a Grant Vortex Oil boiler that's had little use since it was installed in 2013, due to the previous owners long term illness. The boiler & system was last serviced & re-commissioned in September 2021, with a new nozzle fitted & the usual combustion checks, prior to us purchasing the property. The boiler & system has run faultlessly since then but, very recently, the Riello burner has started giving random lock out's but always re-starts after one reset. It’s mostly in early morning after the initial fire up &, generally but not always, occurs once a day. The boiler lives in an attached garage & has a conventional flue; I've checked/cleaned the oil tank filter & oil flow but with no real improvement in lock out incidents. The boiler has had less than 12 months use since we bought the property as it's only used 8 months of the year.
I've gone through both the owners & installation manuals but found them not entirely useful in locating what may be a very simple fault. I am a qualified & competent Mechanical Engineer, generally able to fix most things myself & wondered if there is anything else I can try/look at not requiring specialist test equipment (which I don't have) or should I resign myself to booking a boiler service engineer.
