Ignition failure on Vokera Vision C boiler?

my Voker Vision C boiler has the fault code A01 - we had thunderstorm earlier today and a fuse was tripped, so I don't know if this caused it. A01 fault says 'ignition failure, flame not sensed'. Can i rectify this myself or do I have to call a gas engineer. I tried resetting the boiler but still nothing. Thanks.

Legally, it has to be a Gas Safe certified engineer.
