the boiler stops the gas (i think) and the code shows lights 70 & 80 flashing. "no flame detected" and yet when it first starts I can see the flames, they just don't stay lit. hope this helps
I have a Britony SE combi. When turned on everything starts up the pump runs and the everything goes as normal for 8 seconds but then it shuts down. The water pressure is correct (.75-1.5 bar cold) but it will not stay lit. I have tried serveral times to reset it, but still no joy. can you help...
