I have a Baxi Solo Gas boiler and its stopped working sometime between this monring and yesterday.

Theres no pilot light I can hear a faint ignition spark but cant see anything

Any ideas chaps ? I have gone through the fault finding chart in the manual and it says to check the fuse on the controlboard,im guessing its not the fuse coz I can hear it. Manual also suggests the controlboard itself is faulty

Please help, were all freezing !
