Not 100% sure about this model but it sounds as if either the the heater trip switch has gone off or heating element has broken. if its the trip there should be a re-set button on the back of the unit push it and its fixed!
More likely the Element has broken. If so, i hate to say it but it will need replaced.
If you want to test it, open the unit up and inside you should find a large outer drum that has a heating element around it. This will have two wires attatched to it from a nearby relay with spade connectors. remove these and test the resistance accross the element with a multimeter. if the resistance is either zero or infinite then its is broken for sure and this may cost almost as much as the whole thing did to buy! hope this helps.
