Hi there,
Had a similar fault with a D61DUK this week where the element had failed and caused this problem. Check the element for signs of discoloration and / or blistering as they are commonly visible on a failed tubular element. These signs are usually localised to the area that failed on the element. A continuity test between live and earth will confirm if the element has gone pop (with the machine off the power of course!)
