My boiler is giving me the runaround. The relay chatters between water and heating, sometimes it won't come on at all. The flue sensor seems to be tripping it out - the warning light with 70 on (my central heating engineer says my model doesn't even have a flue sensor!). He's replaced the sensors and we've tried a new PCB, but it's still up the swanny. Any ideas?
