How can I fix my Zanussi ZDC46130W condenser dryer?
 
                The dryer starts ok and runs for a couple of minutes. After a brief pause, which is usual, it stops and the start/pause button flashes with a red light and there is a series of three beeps in quick succession. The dryer then stops working, although if I turn it off and on again it will repeat this process. Any ideas?
