my simpson esprite650 model 22S650 washing machine won't agitate?

hi, my washing machine won't agitate. the motor start wire (brown) has 240v on it. it then goes to a scnchronous motor with gear box attached into a plug which becomes a blue wire then out as a blue wire (internal contact) inside gear box. the small mechanical wire that is attached to the spring loaded mechanism keeps this contact open. would anyone know if this is correct or does the motor have to be energised to wind in the mechanical wire to close the circuit. i tested it by applying 240v to the motor. it wound in the wire and closed the switch. don't know if i'm on the right track .any help very much appreciated
