A simple search of this site will quickly provide you with a list of the possibilities.
The pump is the first culprit then there is the LP switch and the o/h stat.
The LP and o/h can be inspected visually but dont always show any signs.
The pump can be disconnected and see if it still blows the fuse.
There can be lots of other causes as well!
Mending boilers is not always that simple !

A Duff pump usually blows that fuse.
Low water pressure switch usually blows the main supply fuse.
