The electrics have failed on my Hoover AL120. I have replaced the fuse and checked the wiring on the plug. I've taken the back off but cannot get the top off to check the wiring where it enters the macine. The fuse board trips out as soon as the plug is switched on even when the machine is switched off. The machine is 6 or 7 years old and not that great so I am not prepared to pay for someone to repair it. Any help please?
