its probably the same problem i have had 8 warranty callouts for, the machines overheat and trip out the overheat switch on top of the element. on the top inside the top cover on the right hand side is an overload switch that a little buton pops out of when its overheated, reset that and you are away, until next time, the top cover slides back some how and the power needs to be off but i would say you need a qualified repair man to do it.
