The fuse is normally mounted on the circuit board to protect the electronics... question is, why's it blowing?
They are normally rated at just 1amp or so.
An inherent problem with those machines is the gears in the gearbox stripping easily. Replace the fuse & if it still doesn't feed I reckon it could be the gears.
