Hi, I have a Potterton Performa 24, and it seems to have an intermittent fault when it calls for the burner to come on. If I turn on the heating or hot water you can hear the pump and the fan kick in but sometimes it takes maybe 10-15 secs to fire up, when it fires up sometimes the burner light indicator flickers on / off but other times it works as normal. There seems to be no rhyme or reason to it. I had a quick look in the flue just in case it was blocked but it looks ok, also it was quite windy outside so I wonder if the fan is at fault, or perhaps a sensor.
It had a new pcb about 4 years ago, so I'm hoping its not that.
Any ideas would be appreciated. Or any diagnosis tests before I call out a professional.
Thanks in advance
