The direction of rotation can be controlled as shown in Fig.2. When switch S1 is in position A, coil L1 of the motor receives the current directly, whereas coil L2 receives the current with a phase shift due to capacitor C. So the rotor rotates in clockwise direction. When switch S1 is in position B, the reverse happens and the rotor rotates in anti-clockwise direction. Thus switch S1 can change the rotation direction.
The glass section of the washing machine becomes at least warm if not hot during a hot water wash. You can feel the glass area with your hand when the procedure is going on to see if it is warm. If the glass section remains cold to your touch it definitely indicates a faulty heating element. Another sign of a faulty heating element is the non stopping wash process. Some times the washer refuses to go to the next cycle and continues the wash cycle till you stop it. This happens when the water does not acquire the pre set temperature.
