The machine goes through the complete cycle and the clothes are washed properly. However, whenever the drum is required by the controller to turn slowly in a clockwise direction, the motor tries to spin up very fast for approx 1 sec then it slows down to the required speed. The drum rotates anti-clockwise perfectly. I read somewhere that there is a tacho generator on the the motor to send a feedback signal to the controller. Is this associated with the problem and is there anything I can do about it?
