Hi,
The title pretty much describes my problem - A few days ago our boiler started playing up, the hot water went cold and we noticed the fault light on the boiler was flashing 4 times a sec.
After holding the fault button and leaving the boiler for ~30 minutes or so it will fire up again but after a short period (a few minutes) the light blinks as its cutting out and restarting, then it will cut out and fail to restart, and the fault light flashes fast again.
When the boiler fires it produces heat fine at the DHW and CH and demand on either causes the same fault.
Water pressure is at ~1.5 bar cold, I can hear what sounds like the fan after the boiler cuts out, it still runs for a minute or two then stops.
The flue isn't blocked from what I can tell.
I've had a search around and a common fault seems to be the air pressure sensor on these - the part is only £20 but I'm not sure of the legalitys if I bought a replacement and did it myself to see if it does the trick (since its not touching the gas..?)
So I've held off for the moment, and will probably get someone in to sort it, but wanted to get some opinions beforehand so I don't get fleeced for some new parts I don't need!!
