Gorenje Washing Machine not spinning error fault code f4

Why do carbon brushes fail?

The motor carbon brushes transfer the electricity from outside the motor to the spinning winding in the center of the motor. They undergo quite a lot of friction, and after a while wear out.
Carbon is used as it is a reasonable conductor, and is soft enough to wear down instead of wearing down the "commutator"(the ring the brushes press against).
If carbon brushes become too short, contact across the commutator is lost, and the motor won't be able to spin. Brushes often fail on the Spin Cycle first. They are designed to be replaceable in washing machine motors because of this.

Common symptoms for Gorenje washing machine worn carbon brushes:

• Washing machine drum´s not turning;
• Washing machine not turning during the wash cycle;

- The first thing we need to do is disconnect the appliance from the power supply, and remove the screws in the back of the machine that holds the back panel. Careful with the edges of the perimeter.
- Then you need to remove the washing machine belt that is attached to the motor and drum pulley.

- Release the motor of the drum brackets or lugs, be careful it’s heavy.
- Next you need to remove the old carbon brushes and fit new ones according to the video instructions.
