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. Check all wires and connectors generally for internal breakages - caused by movement of the wiring loom attached to the drum. Over a long period of time the wire strands inside the insulator break through metal fatigue. Although the outside of the wire appears ok the internal is open circuit. Pull on each individual wire - if theyre ok internally, they shouldnt stretch. The timer can cause problems of this type, check for burnt connections or of course it could be an internal break in the motor itself, which would require replacement of the motor. Could also be a fault with the motor control board or "module". Replacement with a known good unit only real test unfortunately. Exercise extreme caution in this area - full mains voltage present at serveral places on the board. Power off and disconnect machine when replacing any motor component.
