## Questions & Answers

**Q: I just used twice time and then few months not use it. Now the product can’t  out of the water. How can I fix it?**
A: Sorry can't help on that one, I purchased one about 6 months ago and use it every day with no problems. I would suggest returning the unit under gaurantee for repair or replacement.

**Q: My Airfloss has stopped working. How do I get in touch regarding a replacement?**
A: Hi, there.

Have you checked if the vent is blocked? 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 blocked, it will reduce and eventually stop the water flow. To clean the reservoir vent, follow the steps below:

1. Take a damp/moist paper tower 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 are no debris/dust left

Note: Ensure that there is no debris from the paper tower or cotton bud inside the reservoir area.

I hope that helps, but please know that my colleagues and I are happy to discuss any additional questions with you. You can get in touch via Facebook (@PhilipsUK), Twitter (@PhilipsCare_UK) or via the contact page on our website.

Alternatively, if you think the full product isn’t performing as expected, you can try our new DIY repair/exchange feature, also available on our website.

Cheers, Benji

**Q: Is this a very good flosser and easy to use**
A: I found it works very well and is very easy to use.

**Q: Does this come with everything you need ?**
A: The charger comes with a UK standard 2-pin plug for UK bathroom sockets (it is not a Euro 2-pin plug).  If you want to charge it outside your bathroom you will need a "shaver adaptor" plug adaptor from the 2 pin to a 3-pin plug.
