After weeks of trying to identify when this intermitent fault occurs, I've finally narrowed it down.
When someone takes say a 10/15 minute shower, all is OK. If a 2nd person then takes a shower within 2 or 3 minutes then everyting is normally fine.
HOWEVER, if you wait 15/20 minutes after the 1st person has showered and you then try for a shower or run hot water tap, the DHW demand indicator light comes on BUT the Flame detection light stays off (& the boiler fails to ignite). If you then wait about 20/30 minutes everything is fine again.
Any ideas ??
I do have the Brit Gas cover but dont want to involve them unnecessarily. Armed with the info I have, do u think they could resolve now? (they couldnt find anything last time but have more info now).][/u]
