Zanussi ZDP7205PZ Condenser Dryer that won’t heat?

Hi, We have a 6-y/o Zanussi ZDP7205PZ Condenser Tumble Dryer. Last night it started to make a strange noise and I stopped it immediately. When I opened it, it felt too hot. This morning when I tried to get it going it still turns fine but there is no heat. I am assuming that for some reason the heating part of it is not working anymore. We would prefer not to pay a fortune for an engineer and not to have to buy a new one. A dryer is extremely important to us where we live. Can you help?
