If it is the element and if your kettle is over 12 months old throw it into the bin as Dualit are unable to repair kettle. I know because the element failed on mine , I sent it to Dualit who confirmed the fault and offered me discount off a new kettle but only if purchased from them !! The kettle had been used for 10 months max. I think dualit kettles are expensive rubbish as is their customer service.
