Mend Saunier Duval SD623 Main Combi Boiler

Saunier Duval SD623 keeps fusing main system?

Trying to ignite my combi boiler. every time I press ignite button it keeps tripping the main system. The fuse is fine, all the elements, fa etc have been isolated, and they don't seem to be the cause.

Any advice on how I can sort this out?

Cheers,
Bill

Thanks Ali.
Not very technical, I have to reset the main fuse box which controls the eletric hob and a couple of lights.

Does that make sense?
