F07 means the heater relay is stuck. Switch off machine, take off rear cover and locate the heater at base of drum. trace the wiring back till you find the relay pcb (printed circuit board). the relay is a black rectangular component on the circuit board. Its basically a switch which is stuck in the on position. a sharp tap with a screwdriver can sometimes free it, otherwise its a replacement relay board. check out www.2ndwave.co.uk/manual.html
