Ive got alarms 40 and 80 flashing on my boiler. When the sequence starts the fan comes on the it cuts out. could some one please help me find out what these alarms are.
Thanks
Ben
A friend of mine asked me to price for a new boiler, and I priced for a Worcester. He subsequently had a Chaffy installed (not by me) and is on his 3rd PCB. He could have bought the boiler himself due to the amount he has spent on it. Same fault as yours.
I now have one on the van (bit like the suprima upgrades).
