Worcester Bosch boiler 24i not sparking - can you help ?

The boiler is not firing up - so no hot water or heating. I am pretty sure the reset button is not the issue (raised this in a previous question and had a helpful response). The water pressure is OK and pump and fan seem to be working as normal. But the gas is not lighting up when required i.e. no spark.

So what might be the issue and is there something I can try without calling an engineer ?

Wow... thanks. Worcester 24i same prblem. Just stopped working dont know why. The air preassure switch is the little threaded one at the front leftt of the boiler on the top. Mine was like a dark brown in colour and it was reset with very little preassure from me.

Great site!

After ours made an awful racket when stopping the hot tap with heating on . I had the same fault.

The answer of the common air pressure switch led me to a unit that sits sticking out the top of the boiler.

There was a small pin sticking up so i pressed it down with mild pressure and it moved.

After the pin had moved the boiler worked fine.

So two things THANK YOU for the "Answer"
And
This can possibly be fixed without having to take the covers off.
