Troubleshooting
Toothbrush not turning on
Ensure the toothbrush is charged. Place the handle on the charger and check if the battery indicator lights up. If it still doesn't turn on, contact customer support.
Weak vibration or reduced cleaning power
Check if the brush head is properly attached. Ensure the brush head is not worn out; replace it if it's old or frayed. Clean any debris around the brush head connection point.
Pressure sensor not activating
Ensure the pressure sensor is not obstructed by toothpaste residue. Clean the handle and brush head area. If the issue persists, there might be a fault with the sensor.
BrushSync reminder not working
Ensure the brush head is correctly paired with the handle. The BrushSync feature tracks usage; if the brush head is very old, the reminder may not function as expected. Replace the brush head.

Verify the USB cable is securely connected to both the charger and the power source. Try a different USB port or power adapter. Clean the charging contacts on both the handle and the charger.
