Troubleshooting

My Sonicare AirFloss makes a whistling sound

If your Philips Sonicare AirFloss makes sucking or whistling sounds, you can often fix it yourself by using this troubleshoot.

Clean the vent of your Sonicare AirFloss

  4. Wipe along the outside edge of the reservoir door, also focusing on the vent area
  5. Rinse the cleaned areas with cold water and make sure that no debris is left behind.
  6. NOTE: make sure that no debris is left behind on the inside of the reservoir
