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.
