I have been using a Dyson DC14 upright cleaner for a few years and it suddenly stopped working, I checked the original molded 13amp mains plug and it was fitted with a 5amp fuse and I replaced it with a new 5amp cartridge fuse. On switching on the DC14 it immediately blue the fuse again. So i have fitted a 13amp fuse to the mains wall plug and it now performs OK.
After searching online it seems that a 13amp fuse is the correct one but it had worked for a number of years with the 5amp fuse fitted without any problems ?
