Morning everyone, I was wondering if anyone could give me some advice before i call someone out. I have the above model boiler installed in my terrace, always worked fine with no issues that I can recall. we have just been away for 2 weeks, wasnt on before we went due to weather. When we got back just over a week ago i turned the boiler on and it fired up as normal, then after 10mins I started getting the fast flashing light, the rads started going cooler and the boiler (whilst still whirring away) wasnt lit. I've tried it a few times since and its done exactly the same sequence. The hot water is fine, showers, baths, washing up not a problem. Last night I bled every rad and tried again. This time the boiler stayed on for a good hour (a lot longer than previously) but then returned the flashing light, boiler off etc same as before. Sorry for the lengthy post but i was just wondering if anyone had any ideas or similar experiences of things i could maybe try before calling someone out. Thanks in advance.
