Riello Burner - Post purge lockout

I have Firebird boiler which features a Riello burner. The burner fires up first time without a problem, runs and heats perfectly, however, when it shuts down and completes its post purge, it goes into a lockout state requiring a manual reset. The lockout light flashes red, and the manual says this means there is a "False Flame Signal". The boiler has to be left for 15 - 20 mins before it will respond to a manual reset. Can anyone suggest what may be causing this? Thanks.... Andy

A good service would be ur starting point

it would require a engineer to be in front of the boiler to diagnose the fault.

Hi, check when you last had it serviced. If its been a year or two then I suggest you have it looked at. A service will detect any problems you may have.

When was the last time it had a full service ? IE recommended manufacturers service ?

If I remember correctly the firebird range is oil fired so make sure you get an Oftek registered engineer

Alternatively contact the manufacturer to arrange a service

15 to 20 mins wait sounds like its over heating to me, are you certain that is what the rad flashing light definately means ?.

I would advise getting a gas safe engineer to come and take a look. Not everything is always what it appears to be.

If your local to me I would happily take a look for you.

Firstly has the boiler been kept up to date with servicing, to me it sounds like a carbon build up across the rectification probes, I would suggest a service and possibly an hour labour to carry out a quick repair, it could also be the electrical unit on the burner itself, no way of knowing until it's been tested
