Philips Sonicare 4100 Troubleshooting

Troubleshooting & repair
My Sonicare toothbrush makes a loud noise
If your toothbrush makes a loud noise, the troubleshooting tips below may help you find a
solution.
We recommend you follow the steps in the order listed below. In between steps, check to see if
the issue is resolved before moving to the next. Alternatively, you can watch the video below to
solve the issue.
1. Getting used to an electric toothbrush.
Sonicare toothbrushes use powerful vibrations to clean your teeth. The sound produced is louder
than a manual toothbrush. If this is your first electric toothbrush, it can take a while to get used to
electric brushing.
2. Place a brush head on your toothbrush.
If you turn on your toothbrush without a brush head, it will make more noise. Always ensure that
a brush head is attached to your toothbrush.
3. Place the brush head correctly.
If your toothbrush makes an abnormally loud noise, a loose brush head may be the reason.
Ensure the brush head is firmly placed on the handle and not loose. A small gap will remain
between the handle and brush head as needed for vibration.
