I also have the same problem, thought there was a problem from first use of machine as it seemed to keep stalling. then on the fifth time of trying to use it , the machine stopped alltogether, from loads of internet searches it seems to be a recurring problem. The machine is now gathering dust in a cupboard. From what I can gather it's going to cost more to repair than replace, but am phoning kenwood tomorrow just to check.
