My shredder fails to operate

Is the shredder connected at the mains and is the power turned on? Is the shredder switch set to ‘auto?’ Is the shredder located correctly on top of the basket? Press down firmly on the shredder head to ensure it is in the correct position. Has the shredder over heated? Turn off at the mains and leave to cool down for 60 minutes then try again. Has the shredder blown a fuse? Turn off at the mains and try replacing the fuse in the mains plug.
