The model number is alpha CD30S
and the 'B' light is solid not flashing. It normally runs for a few hours before cutting out
Thanks in advance for any help
Hi
Got an alpha boiler (2years old) not sure of model but it runs the heating for a few hours then cuts out. The 'B' orange light then flashes. I can restart it by reseting the dial but a couple of plumbers have come round and scratched their heads and haven't really had a clue.
Could...
