Cause 1

Carbon Brushes

A common part that can prevent the machine from washing is the carbon brushes. If your washing machine is not turning the drum when it’s filled with water or on a spin cycle the problem can be due to worn motor brushes.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Depending on your model, remove the backplate to access the motor
  • Remove the motor and check for any signs of damage
  • Remove the carbon brushes and check for any signs of wear, replace if required.
