含义
刷头传感器异常。牙刷无法识别已安装的刷头，或刷头识别功能工作不正常。
常见原因
- 刷头识别RFID标签损坏或脱落
- 牙刷内部RFID读取天线接触不良或受潮
- 非原装刷头不兼容——第三方刷头可能不包含RFID标签
- 刷头识别窗口被牙膏垢覆盖影响读取
- 刷头识别模块电路故障
自助排查
- 清洁刷头与手柄连接处的传感器窗口——去除牙膏垢
- 更换为原装Philips刷头测试识别功能
- 确保刷头完全卡入到位——听到”咔嗒”声
- 如识别功能间歇失效——可能是RFID天线接触不良
- 不影响基本刷牙功能——可忽略此提醒继续使用
English
Meaning
Brush head sensor anomaly. The brush cannot detect that a brush head is installed, or the brush head identification function is not working.
Common Causes
- Damaged or detached RFID tag in the brush head
- Loose or moisture-affected RFID reader antenna inside the handle
- Incompatible third-party brush head — non-genuine heads may lack the RFID tag
- Sensor window covered with dry toothpaste residue blocking the RFID signal
- Faulty brush head detection circuit on the main board
Self-Check Steps
- Clean the sensor window area between the brush head and handle — remove toothpaste residue
- Test with a genuine Philips brush head to verify the detection function
- Ensure the brush head is fully pushed onto the drive shaft until it clicks
- If detection is intermittent, the RFID antenna contact may need service
- The brush remains fully usable for brushing — the sensor fault can be ignored for basic operation
