Check the tacho coil for breakages in the connections. The tacho coil is a small generator coil on the end of the motor which provides a voltage proportional to the speed of the motor. This voltage is fed back to the speed control module to enable the machine to check the rotation, direction and speed of the motor. If the machine goes into spin as soon as you turn it on, the tacho coil on the motor is faulty or come off, sometimes the screw holding it on has just come undone and it has fallen off or the outer casing has come adrift.
