fault finding on bai combi boiler

[loganathen]

my baxi boiler does not lit up , the red light flashes on all the time indicating flame failure and cannot light up the boiler , pump runs for 30 seconds , no fan is working and boiler does not ignite, what can be wrong please

What model is it? Is it permanent pilot or electronic ignition?

The spark electrode could be out of position/dirty, or the piezo device generating the spark, broken or it could be a loss of gas supply.
Try posting the question under �Home & Garden� or �How it works�, these are more common locations for questions such as yours.

the model is baxi 105HE

This boiler has an electronic ignition, from what you say it could be a fault with the ignition PCB, Control PCB, the spark electrode or a wiring fault � either way you are going to have to get someone out to look at it.

If it only needs adjustment, you might get away with a fix for less than �50, otherwise if a PCB requires replacement you could be looking at anything up to �200.
