You should replace the fuse only once.
This means you've got a problem with either the circuit or the appliance.
As Red Squirrel said, move it to another line and see if it blows another fuse. If it does, the appliance is defective. Throw it out.
If it doesn't fry the fuse, plug something else into the questionable plug. Something like a toaster oven or a toaster. If it blows again, it's the circuit. Fix it or have it fixed by an electrician.
