The AirFloss nozzle and reservoir vent is clogged or dirty.
If the AirFloss becomes clogged, it is important to clean the inside and outside of the nozzle, as well as the reservoir vent.
To clean the nozzle, follow the steps below:
1. Remove the AirFloss nozzle from the handle
2. Rinse the nozzle with warm water. We advise you to clean it after each use to eliminate the residue
To clean the reservoir vent, follow the steps below:
There is a small vent in the reservoir door opening (where you put the water/mouthwash) to let air in as water is drawn out. If the vent is clogged or dirty, it will reduce and eventually stop the water flow from coming out of the nozzle.
1. Take a damp/moist paper towel or cotton swab
2. Wipe along the inside edge of the reservoir door opening, especially on the top area
3. Rinse well with cold tap water and ensure that there is no debris/dust left
Note: Ensure that there is no debris from paper towels or cotton swabs inside the reservoir area.
Charging your AirFloss
If this is your first time using the AirFloss, it is important to charge it for 24 hours before using.
Another tip to ensure that your AirFloss stays charged, leave it on the charger when not in use. Leaving it on the charger will not damage your AirFloss.
Note: When it is fully charged, AirFloss has an operating time of up to 2 weeks (or 14 uses).
Note: When the charge indicator flashes yellow, the battery is low and needs to be recharged (fewer than 3 uses left).
Press the power button to ensure that your Sonicare AirFloss is on.
Place it on the charger
If your AirFloss is still not turning on, you can try charging the device by plugging the charger into a live outlet and place your AirFloss on the charger.
Charging process:
* 1 green LED: 33% charged
* 2 green LED: 66% charged
* 3 green LED: 100% charged
Note: If you are using your Sonicare AirFloss for the first time, ensure that it is charged for 24 hours.
Note: When the charge indicators flash yellow, the battery is low and needs to be recharged (fewer than 3 uses left).
If you are using your Philips Sonicare AirFloss for the first time, a little discomfort or bleeding can occur. Read more information below on why this happens.
Using for the first time
When starting a new oral care routine, it is normal for your gums to bleed. One reason for this is because you may not have been cleaning in certain areas that cannot be reached.
Any discomfort will disappear as your gum health improves.
Note: If bleeding is excessive or does not stop within 3 to 4 weeks of regular use of AirFloss, consult your dentist.
If you see any leakage from your Philips Sonicare AirFloss, check out our tips below on how to solve this issue.
Leakage from the nozzle
If the leakage is coming from the nozzle area, try to remove and re-insert it to ensure that the nozzle is fully inserted. There should be a small gap between the nozzle and the handle; this is normal.
Leakage from the reservoir
If the leakage is coming from the reservoir, there are two solutions you can try.
Reservoir door/cover
After re-filling the reservoir with water/mouthwash, ensure that the reservoir door/cover is closed. You should hear a clicking sound.
Too much water/mouthwash
Ensure that you do not put too much water/mouthwash inside the reservoir.
