Baxi Potterton Main Combi 24 HE Boiler - Flame Failure

[*Yasmin*]

Hi there!

Wonder if anyone can help?

I have a Baxi Potterton Main Combi 24 HE boiler that is 2 yrs old.

It has been fine until yesterday when the flame failure light came up red and started flashing when i turned on the hot tap. I tried re-setting the boiler but the same thing happened again. It also flashes red when you try to put the central heating on. So we have no water or heating at the moment.

Does anyone have any idea what might be wrong? I've had no problems with the boiler until yesterday. The pressure bar at the moment is showing 2 (with boiler switched off) it rises to just under 2.5 when the boiler is switched on.

Thanks in advance.

Yasmin

Have you got gas in the meter???

Other than that its a job for a gasman

could be PCB, gas valve or ignition components.

I've got a new PCB, flame sensor and sensor lead for this boiler (and am in Hertfordshire) if you want to email me.

Hello again

Just a update....

An engineer has been & replaced the 'electrical switch' and it is now working fine.

Many thanks for your replies.

HI Yasmin



which electrical switch to be exact please ?

Hi there

Sorry i am not sure. The engineer was not here long, 20 mins or so and said it was the electrical switch that was replaced, the boiler now fires up with no problem.

I have the same model.

The manual fault finder section points you to the on/off/reset switch as one of the possible causes of this kind of fault.

while i am on here! (sory posted this in seperate thead by mistake last night)

Has anyone suggestions for cause of an intermittent fault on a main 24he bolier? Made by Baxi and very similar to other models.

Flame failure is intermittent. I have reset bolier.

Seems to work for a while on both hotwater and ch then not work. Cycle starts again..

I have followed manual which pointed to pcb - this replaced but still the same.

thanks

it was the air pressure switch

it was the air pressure switch

In that case one wonders why you replaced the expensive PCB first ?

Well above people have replaced an "electric switch" and an APS.

However, there are many faults which can cause the problem that you have.

But all of them need a competent CORGI engineer as the fault investigation involves the gas train.
