Philips, the manufacturer of Sonicare toothbrushes, offers a 24-month warranty on most models, but some only carry a 12-month warranty. To confirm a 24- or 12-month warranty on a toothbrush, you can either call Philips or lookup the specific product online.
Philips offers a warranty on Sonicare toothbrushes purchased within the United States and Canada. The warranty does not apply if the toothbrush was manufactured in a country other than where the product is used. A proof of purchase is required, and the warranty begins on the date of purchase.
The company only offers the warranty if the product was used for its intended purpose and if the operating instructions were followed. The warranty does not cover brush heads, misuse, abuse, neglect or alterations of the product. It also does not include normal wear and tear, such as chips, discoloring or fading. Philips do not cover losses consequent in nature and other limitations may apply.
If you are having a problem with your brush, first consult the owner's manual for troubleshooting tips. The owner's manual can be found on the Philips website for download. If it is still not resolved, you can contact Philips online or by telephone using the number listed in the owner's manual or on the website.
