Err4 - 飞利浦 净水器

中文

含义

水质传感器异常。净水器出水水质检测传感器读数异常或持续显示不合格水质。

常见原因

  1. 水质传感器（TDS/电导率探头）表面结垢影响测量精度
  2. RO膜穿孔或密封圈失效导致脱盐率下降
  3. 后置活性炭滤芯未冲洗干净——新装滤芯初期炭粉渗出
  4. 水质传感器连接排线松动或受潮
  5. 传感器长期未校准导致零点漂移

自助排查

  1. 放水冲洗3-5分钟后再检测水质——排除管路滞留水
  2. 拆下水路中的水质传感器探头——用柠檬酸溶液去除结垢
  3. 检查RO膜使用时间是否已超期——超过24个月建议更换
  4. 新换滤芯后多冲洗10分钟——炭粉冲洗干净后水质会改善
  5. 用TDS笔手动测量对比——确认传感器是否需要校准

English

Meaning

Water quality sensor anomaly. The output water quality sensor reading is abnormal or continuously shows unacceptable purity levels.

Common Causes

  1. Scaled TDS/conductivity probe surface degrading measurement accuracy
  2. Perforated RO membrane or failed seal ring causing reduced rejection rate
  3. Post-activated carbon filter not flushed — carbon fines leaching from a new filter
  4. Loose or moisture-affected water quality sensor ribbon cable
  5. Zero-point drift from prolonged use without calibration

Self-Check Steps

  1. Flush the system for 3-5 minutes before retesting — stagnant water in the lines may give false readings
  2. Remove the sensor probe and descale with citric acid solution
  3. Check if the RO membrane is overdue — replace if in service over 24 months
  4. After installing new filters, flush for 10 extra minutes to clear carbon fines
  5. Cross-check with a handheld TDS meter to determine if the sensor needs calibration
