You have a short circuit in the machine. Most likely culprit is the heater followed by the main motor.
Power off, drag machine out onto the floor, remove back cover or tip machine up at an angle. Check the heater, heater connections, thermostat connections and the connections on the timer, (looking for a burnt out terminal or wire).
Heater is located at bottom of drum. If testing with a multimeter, disconnect the wiring and take a resistance reading across the terminals - should be around 20 ohms. If heater is blown (broken internal heater wire) it will give an infinite resistance. There should be no continuity between the either terminal and the metal sheath of the heater - if there is, there's an internal short circuit. When removing heater, disconnect wiring, undo central mounting nut and prise it out of its rubber seal - may require some effort. Replace heater, use sealant when refitting rubber seal and ensure it is fully pushed into the recess in the backplate. Make sure the element locates into mounting bracket inside the drum.(look inside the element with a torch and you will see mounting bracket). This bracket ensures that the moving inner drum doesnt strike the element and damage it.
Check out the carbon brushes in the motor. Theyre graphite blocks which transfer mains power to the copper segments of the motor. Power off, drag machine out onto the floor, remove the back cover and locate the motor. May help if the machine is tilted at an angle or laid on its side. The brushes are at the other end of the motor from the drive pulley. The holders are plastic or bakelite and are generally held in with screws or plastic clips. Also, look at the copper segments they run on to check for burning or pitting.
Closely inspect the entire wiring loom and circuit boards, looking particularily closely at areas where the wiring touches the machine frame. Your'e looking for any signs of wear or fraying which would allow the bare wire to contact the frame.
