含义
高温异常警报。净水器内部温度传感器检测到水温过高，设备自动停机保护以防止损坏。
常见原因
- 即热模块温控器故障导致持续加热失控
- 加热元件干烧——水路缺水但加热器仍在工作
- 温度检测热敏电阻失效——测量值与实际温度偏差大
- 水路堵塞导致水流不足——加热腔内水温局部过高
- 散热风扇（如有）故障导致热量积聚
自助排查
- 切断电源，待机器冷却30分钟后重新上电
- 检查水箱是否有水——缺水时不要启动加热
- 检查水路是否通畅——出水流量明显偏小需疏通
- 用万用表测量热敏电阻阻值——与温度对照表比对
- 若热敏电阻正常仍频繁过热——检查温控器和加热模块
English
Meaning
High temperature anomaly alert. The internal temperature sensor has detected excessive water temperature — the unit automatically shuts down to prevent damage.
Common Causes
- Failed thermostat in the instant-heating module causing uncontrolled heating
- Dry heating — heater element energized without water flow
- Faulty NTC thermistor producing readings that deviate from actual temperature
- Blocked water path causing localized overheating in the heating chamber
- Cooling fan (if present) failure causing heat buildup inside the unit
Self-Check Steps
- Disconnect power, allow the unit to cool for 30 minutes, then power back on
- Check the water tank or supply — do not run the heater if water is unavailable
- Verify flow path is clear — significantly reduced output indicates a blockage
- Measure the thermistor resistance with a multimeter and compare to the temperature-resistance chart
- If the thermistor is good but overheating persists, inspect the thermostat and heating module
