Oral B pro toothbrush humming but not moving the brush spindle.
텍스트:
Battery is fine. Have cleaned the whole brush and casing. When the button is pressed, the motor starts but this does not result in the spindle that operates the brush moving.
Cannot see any obvious breaks. How do I check the connection of the spindle to the motor?
Thanks
