The heating boiler works a treat all year around until its minus ten then decides to stop 
Flame fault so trying to plug my "My Naff Code Reader" in it

Not lighting?  What boiler?

[albitz]

Crank sensor - no signal - no spark. No spark - no flame.

Not lighting?  What boiler?

The Boiler says on it, Main Combi 24 HE
Mrs. Looknee noticed that the Flame Failure light was on. So it turned the dial to reset held it there for 20 seconds then turn it back to on, the boiler licks in and seems to be working fine for just under 2 minutes then the Flame Failure Light comes back on.. I have repeated this a few times and the same happens each time

[Debs.]

Perhaps water in the gas supply pipe/meter?.......reduces flow and pressure and causes flame instability; quite common in some areas and if so, you need the gas board to come and suck it out.

Bet its the thermocouple, have you got a pilot light youth

[albitz]

I would think there is enough hot air in the Knee homestead without the need for a boiler.

bad news in the middle of winter..

go buy some electricity heater and blanket before shops close :-/

some years ago electricty cut and that night was awfull.. hurry imo..

[PhilRich]

Faulty Air Pressure Switch maybe? Part No. 5112999iirc  :-/





Just a thought Daz...check that the flue hasn't become partly blocked by ice/snow other debris, it could be that simple, then again...... :-/

Check the condensate drain is not frozen............it would seem most plumbers are demonstarting their incompitence on fitting modern boilers and how they are totaly incapable of following basic manufacturers fiting instructions. (as I have seen 7 like this in 2 weeks!)

[Marks DTM Calib]

Heres the installatrion guide which will show you where the condensate drain is (and it also tells you how it MUST be installed!)

My money is on the condensate drain spent three hours defrosting one for some one today>

If it's external and not in 32mm disconnect at boiler end and stick a bucket under the drips, Not ideal but gets you heat and hoidioter overnight

The circuit bord on mine decided to throw in the towel the other day, bloody freezing in the house, lucky to have it fixed the next day 

[davethediver]

Most people don't realise how much they relie on the boiler unil it breaks down this time of year in both my last two properties ive only had the CH boiler no fires 

[Darth Loo-knee]

Yeap you were right Guys, this little condensation catching plastic bottle was full and the pipe that is supposed to take it outside must be blocked, i lagged the pipe outside the other week so that obviously has not worked.
Just got the heating back on so i will have to keep my eye on the level of water.
