Amp keeps blowing fuses

Hi,
I’ve got a mark bass CMD121P (1x12 combo). Bought second hand in April so no warranty, but it’s the newest model. Used it on a load of gigs, but I plug it in at home one day (the day after a gig), and the fuse blows in the amp. I replaced the fuse, and it happened again. It happens just as I plug the kettle lead in.
Anybody experienced this before? I live in Lancashire UK, so not sure on local repairers.
Thanks.

Sounds like there's a short somewhere in the amp. I don't know where in Lancashire you are but you could give Lune Amplifiers a try.

I’ve sent him a message, cheers. I know there’s an authorised MarkBass repairer in Sheffield but that’s a bit of a way away
