Hello, I wonder if anyone can help please as I am at my wits end.
I have a British Gas 330+ condensing boiler. Most of the time it works perfectly fine but when there is a sudden drop in the outside temperature the boiler cuts out and there is no heating. I can restart, and after a few goes it will fire up and works for quite some time but again if there's a further sudden change in temperature outside it cuts off again. I have had numerous engineers out and they have been unable to identify what the fault is.
It comes up with F22 fault which implies that it is dry. The pressure seems fine a 1 it has had a new pump in recent times and all seems to be intact but there is something when the weather temperature changes that triggers the fault,
I have two Flues on the outside wall. The bottom one is the hot water boiler and the top one is the heating boiler when they are working hard the hot water boiler vapour pushes up and maybe getting sucked in to the top flue for the heating someone has suggested that could be causing the trigger to cut off.
Any thoughts with you very much welcome.
