Hi all, Joined this group in the hope of getting some advice, here goes, I have a fer falcon combi boiler, when the heating comes on, either by timer or manually, the boiler fires up as it should, however it then shuts down (although the pump can still be heard running) . If I then run some hot water (which works fine) the boiler then ignites as normal after the couple of minutes stand by period. Anyone come across this problem before? Thanks in advance, John
