Boiler not firing after fuse in control panel blew

[fushia34]

I'd be grateful for any ideas. Fuse blew in control panel. Replaced it but F5 error keeps coming up. Have pressed reset button and boiler now fires up but heats up to 90C for a moment and then goes off. Thought that just replacing the fuse would sort it but did the fuse blow because of a fault? Any help would be appreciated.

Could be a pump problem, pump blew fuse, now won't circulate, hence overheating?

Boiler info would help.

Glowworm boiler installed about two years ago. Thanks for replying.

I've had this. If Boiler has small fan for cooling which has become faulty (hence blown fuse) then it will shut off if in danger of overheating.

Thank you - we'll probably have to call someone out. Sounds like the fuse blew for a reason!
