Hi got a Whirlpool American style tumble dryer. Model 3LER5434DQ1 Blowing periodically the 13 amp fuse in the plug and on an extension lead (Its pluged into an extension lead and straight into Walled 13 Amp Socket). Is the fuse under rated for the Appliance ? Should the Appliance be fed by its own Power supply at a higher Amp Rating ? Cheers
