My Creda suffered the same problem of not spinning. Based on what I have read, the carbon brushes on the motor wear out and need replacing. I just took mines apart and will call Creda parts in the US for a price on the part. 800-800-2733. Check out the vido, you do not need to take the motor out to replace the carbon brushes.
