My ideal ICOS HE15 boiler keeps coming up with a flame error when set to a boiler temperature above mid way. When set low it never (well once actually) comes up with the failure. The boiler has been serviced recently and had the spark electrode replaced and that did not cure the problem. The condensate trap is clear. When I press the reset (when the boiler has cooled down) it always relights but fails later on when warm. I don't beleive its going out but fails to light when heat is called again.
Its strange that it only happens when warm. Any ideas. I don't want to call out another engineer who will simply replace parts, I need a good diagnosis first. If all else fails anybody know and good guys in the derby area who can help. The ideal helpline just say call a man out !
