HAD THE SAME PROBLEM WITH MY HOOVER HW 120M ,NO HEAT WHEN USING TUMBLE DRYER,CAME ACROSS THIS SITE YESTERDAY AND READ THAT THE HEATING ELEMENT HAS A CUT OUT SWITCH.SO I UNPLUGED IT SLID THE TOP BACK AND FOUND A LITTLE BUTTON IN BETWEEN THE TWO ELECTRICAL CONNECTIONS ON THE TOP OF THE ELEMENT TOWARDS THE FRONT OF THE MACHINE,I PUSHED THAT IN, IT CLICKED ,SO IT HAD TRIPPED OUT , PROBABLY BECAUSE I HAD USED IT WITH TOO BIG A LOAD TO DRY AND NOW WORKS FINE AGAIN. HOPE THIS HELPS YOU .
