I have exactly the same problem as Steve. I have the CSI 85AT that does not have a pilot light so its not the pilot nozzel blockage faults found on the CSI 85T. Does anybody know what the fault is that causes the boiler to go through its start up cycle, but keeps failing to ignight for more than a few seconds in C/H mode. But works fine for drawing hot water. Once the hot water has run for a minute or two, the boiler then works fine on central heating mode?
Help, thanks Neil
