Electrical faults sometimes cause too much current to flow risking electric shock to the user or fire from overheated wires. The fuse is intended to break the electrical circuit automatically if an over current happens. Sometimes a fuse just gets old and tired and melts of its own accord. In your case, with fuses blowing one after another, you have a dangerous electrical fault. Have your machine serviced or buy a new one. Argos UK have one for £25 which is incredibly cheap and a Panasonic for £199.
