Hi,

I have a Baxi combi boiler 80e and I'm having problems. It's been dodgy
for the past two weeks. I have had to keep the clock on 'constant', then
the heating would fire up for a little while then switch off, then fire
up again, switch off etc. This was not ideal, but kept the house warm.

Today it won't work at all. The pilot will light, I get the initial
'click n whoosh' thing, and can see the burner lighting, but then it
will just go out. The power and heating green leds stay on, but the
flame warning light then flashes. The pressure is fine - 1.5. I also
can't get any hot water. I've been resetting it, switching it off, etc
for hours now with no joy.

Does anyone know if there's anything I can do myself to get it working
again? I'm assuming it's not the thermal coupling,as I read somewhere
that it wouldn't even light if the thermalcoupling was gone? (I know I
might be wrong here) I can't afford a heating engineer until I get paid
at the end of the month. I'm freezing, so any help would be greatly
appreciated..

Thanks for reading.. I hope someone can help me out.

Is the pump running?

Bob

On this boiler there are diagnostics. If it were the pump then the light flashing would be the one which looks like a circle with a cross through it, that represents the pump. I think that the flashing light you have indicates a problem with the main burner. There is a flame proving circuit known as a flame rectification. There are various electrical leeds between the burner compartment and the pcb (just behind the plastic backing to the pull down front flap). One leed is the Ht leed which lights the gas and the others conduct a direct current. The flame acts as a diode allowing current to pass in one direction, if there is no flame there is no current and the boiler goes into lockout. In your case there is an initial flame, and the warning light you are getting implies perhaps something as simple as a leed has come off or is shorting out. Check that and get back.
