remove the motor and then remove both motor brushes.if the carbon bit is less than 10mm they are worn out and need replacing.if you pull the carbon bit out of the holder and refit you can sometimes get the motor to work to prove the point that they are worn out and causing the problem.DO NOT run machine with stretched brushes (for test purpose only) as they can come out the holder and destroy the motor
