The tachometer or tacho-generator has the function of controlling the electric motor and the speed of the motor (rpm). So, could be electric motor blocked for some reason, worn out carbon brushes, faulty tachometer, wiring and finally electronic.
After 5 years working of washing machine, by my experience the most common reason is worn out the brushes of electric motor.

Dear Aung Ko Ko Min,
From my long-standing practice and according to the electronics manufacturer's recommendations that those in household appliances do not repair. Why is that so? Because it requires knowledge of a new area such as electronic components and can be very dangerous if inappropriate equivalents are used which can result in a fire or electric shock. My advice is cautious with electronics repair only with the assistance of a qualified person who knows what he is doing.
