My Philips Sonicare toothbrush is not turning on
Does your Philips Sonicare toothbrush no longer turn on? If there are no vibrations when you press the power button, you might want to use these possible causes and solutions to try and solve this issue yourself.
The handle is empty or not fully charged
Do you see the battery indicator blinking or do you hear a beep when you put the handle on the charger? If so, this means that the handle is working properly but needs to be fully charged first. Fully charge your Philips Sonicare toothbrush. This can take up to 24 hours.
The power button is stuck
Toothpaste or debris could get inside the small gap around the power button. This might cause the power button to get stuck and stop working properly. Clean the power button and the area around it with a damp cloth to make sure it is free of debris.
Socket is not working
Try another appliance in the same socket. If that appliance is also not working, the issue might be with the socket. Try a different outlet to fully charge your Philips Sonicare toothbrush. You might need to reset a GFCI outlet.
Not using the original charger
Make sure that you use the original charger that came with your Philips Sonicare toothbrush. Charging components are not interchangeable.
