Candy Aquaviva 1000 Automatic Washing Machine?

The machine stopped soon after the start of a wash cycle after filling with water and revolving a few times. The pilot light above the 'on' switch had gone out. I changed the fuse in the mains plug and switched it on at the mains. I pressed in the 'on' switch again and there was a dull 'pop' from the area of the switch and nothing further happened, the machine refuses to switch on.
