Ferroli Optima 701 - Pilot light extinguishes

[leemel]

Hi Guys,
Problem with a Ferroli (don't, I already know, the F word)
Pilot light extinguishes when DHW is called for and the CH is on. Bit of a pain when you have to turn heating off every time you need to run a sink full of water or a bath or wash your hands after a .....
Any suggestions (other than the obvious change the bioler for a Baxi or Worcester) would be greatly appreciated.

fan is going but you would need an gas safe registerd person to change it and make sure

Hi, Thanks for the reply.
I have managed to get to the boiler today and saw the fault occur. The LED fault lights illuminated are 1 and 2 and the others are not lit. This doesn't seem to be a problem according to the manual.
If it is the fan, wouldn't that be a problem when the CH is fired up too?
