How to Fix Your Sonicare Toothbrush if It Won't Charge

The Sonicare, manufactured by Philips, is an electric toothbrush that runs on a rechargeable battery. The battery uses a charger that plugs into a standard power outlet. If the Sonicare toothbrush will not recharge, the problem is fixable as long as the battery or circuit board is not the issue. The rechargeable battery and circuit board can't be replaced. The battery and board are integrated, and removing either of them will damage the board. If the battery will not recharge, the entire Sonicare toothbrush must be replaced.

Place the bottom of the Sonicare toothbrush into the charger. Plug the charger into a live outlet. Allow the toothbrush to charge for 24 hours. When the toothbrush is fully charged, the LED will show a solid green light. If the Sonicare toothbrush still will not charge, go to the next step.

Plug the Sonicare charger into another power outlet to see whether the first outlet was the problem. Make sure the new outlet is working before plugging the charger into it. If the first outlet was the issue, the LED light on the charger should now light up and it may beep three times. Allow it to charge for 24 hours. If the LED is still not lit, go to Step 3.

Unplug the charger from the power outlet. Wipe the surface of the charger with a damp cloth to clean it. Set the charger out of direct sunlight and allow it to dry. When the charger is dry, plug it back into the outlet and place the Sonicare toothbrush in the charger. If there is no LED light, the circuit board might be damaged or the rechargeable battery may be depleted. The toothbrush will need to be replaced.
