Biasi Combi boiler doesn’t light


I have a Biasi Prisma 24SE combi boiler, and I tried to release the air from the system and then refill with water. Everything went fine- at last I thought so till I tired to light the boiler. It didn’t work for the first time so i restated and then restarted and then…. again. Now boiler doesn’t work. Any idea on what may have gone wrong and how to correct it?
Any help appreciated


Hi Bruce

How many times did you press the reset button? Did you let the boiler to cool down between pressing? Each time boiler tried to light (lighting sequence started) but failed? My guess would be that the air is locked inside of the boiler, replacing air vent should solve the issue.
