Please can anyone help?? I've been without hot water for the past 4 weeks and no heating for 4 weeks also. :(

Basically the boiler ignites then dims but goes straight out indicating flame failure on the boiler.

We've replaced the air pressure switch, checked the flume and the circuit board has been replaced.

The boiler is only 2 years old and we're running out of options!

How does your condensate run?
Undo te white pipe from underneath the boiler and blow down it reattach and try again.
If not it is most probably the flame recognition probe which is not realising the flame is there, both are minor faults on these excellent boilers

When you say "it dims" what do you mean. Flame or lights
 
You really need to call in someone who is qualified to work on gas,otherwise its guuess work and dangerous
 
Thanks for all posts of help!

Basically the boiler lights then dims which its supposed to do but instead of dimming it goes out. Then the boiler shows a red light against flame failure.

We've had a corgi registered engineer looking at it and he's stumped!
 
time to get another RGI in, sounds a pretty simple fault to me, it is a fairly simple boiler inside and remember you shouldn't have to pay for any parts supplied that do not fix the problem

Its better to find a Gas Safe registered engineer as they are usually more up to date.

You should certainly not have to pay for parts which do not effect a repair.

Did your CORGI check the gas valve settings? It probably only needs a little tweak!

Apparently yes the gas valve settings were checked.

The annoying thing is it ignites but within 5 minutes goes out!
 
There are TWO settings needing checking on the gas valve.

Are you quite sure he checked BOTH ?

Many people only check one of them!

Its the other which can cause this fault!

80%. Of the time on these main boilers it the air pressure switch, especially when the problem is intermittent.
 
I'm having issues with the same boiler too (see the other 24 HE thread) and having replaced the PCB - which was the faulty part supposedly diagnosed by the engineer that visited I still have the fault! urrrgggg!!!!!!

Anyway I was going to try the air pressure sensor next and it you're willing to sell it I might be interested?

drop me an email on [email protected]

thanks
