My Philips Sonicare DiamondClean toothbrush does not charge
Is your Philips Sonicare DiamondClean or DiamondClean Smart toothbrush not charging? Use these possible causes and solutions to try and solve the charging issue yourself.
Handle is not fully charged
Place your handle on the charger. If you see the battery indicator light (below the modes) blinking, or if you hear a beep, it means that your toothbrush is charging. Fully charge your Philips Sonicare DiamondClean toothbrush for 24 hours.
Not using the original charger
Make sure that you use the original charger that came with your Philips Sonicare DiamondClean or DiamondClean Smart toothbrush. The charging components (charging base, charging glass, travel case) are not interchangeable.
Outlet is not working
Try another appliance on the same outlet. If that appliance is also not working, the issue might be at the outlet. Try a different outlet to fully charge your Philips Sonicare toothbrush. You might need to reset a GFCI outlet.
The surface or other chargers are interfering
Metal surfaces or other chargers may interfere with your DiamondClean or DiamondClean Smart charger. Make sure that the charger is not placed on a metal surface or near other chargers. Place the charger in a different position and try again.
Toothbrush is placed incorrectly in the charging glass
Make sure that bottom of your toothbrush is touching the center of the charging glass or on the charging pad.
Firmware is not updated

Tap on the menu icon in the top left corner
Go to 'My Products'
