THANK YOU THANK YOU THANK YOU.. I'm not at all technical and I managed to take off the back of my dryer ( bought a cheap set of screwdrivers with Torx 20) in TKMAXX, pried off the back (unplug first of course) found the red reset button (only button visible) and hey presto it worked again! Must keep the filters spotless now as that was probably what triggered the fault.
