Biasi Combi Boiler Flashing Green Light

Hi Folks,

I bought my Biasi Combi Boiler three years ago. From last 2-3 days, I was out on vacation. When I went back & checked my boiler, I noticed that it is not working and flashing green light. Someone, please tell the reason behind it. How can I fix it at home?

Thanks a lot

Hi Lisa

When the green light flashes on the Biasi boiler, the problem could be due to the faulty fan & bad signals of the air pressure switch. I would advise checking either boiler’s fan is working or not as sometimes fan can seize & it is sufficient for the boiler’s air pressure switch to suspect that boiler is unsafe & eventually it will lock out the boiler. However, if the fan is working properly then, there is a signal issue.
