O.K. Zanussi/Electrolux et al are a bunch of fuckers,not putting the total load in the user manual in the forlorn hope it'll prevent people wiring it up by themselves.Nobody has told them that security by obscurity doesn't work.
On the site below it has fuse rating of 30amps so 6mm is fine.What existentialist says is technically true but is probably not worth worrying about if an actual fault occurs it'll blow a 40amp breaker as easily as a thirty.
