Circuit Diagram for Hotpoint TDC30p?

The tumble dryer stops after about 10 mins and pushing the start button has no effect...After about another 5-10 mins I can then start it again.Just wondered if there is a thermal cutout on the motor circuit?...After reading several posts I was convinced it was the start relay,but if I understand it correctly if it was the relay it should start again after I've pushed the start button again.
Thanks for looking at this post
