含义
进水电磁阀故障。进水电磁阀无法正常打开或关闭，导致净水器不出水或一直处于制水状态不停机。
常见原因
- 电磁阀线圈烧毁或断路——阀芯无法动作
- 电磁阀阀芯被水垢或杂质卡住无法移动
- 电磁阀膜片老化变形导致密封不严
- 电磁阀供电电路异常——控制板继电器或MOSFET损坏
- 进水压力过高导致电磁阀无法正常关闭
自助排查
- 断电后听电磁阀是否有”咔嗒”吸合声
- 拆下电磁阀进口端——检查阀芯是否被杂质卡住
- 用万用表测量电磁阀线圈电阻——开路则线圈坏
- 测量电磁阀工作电压是否在额定范围内
- 清洁或更换电磁阀滤网——拆卸阀体清除水垢
English
Meaning
Inlet solenoid valve failure. The inlet valve cannot open or close properly, causing the purifier to produce no water or to run continuously without stopping.
Common Causes
- Burned-out or open-circuit solenoid coil — the valve core cannot actuate
- Valve core jammed by scale or debris
- Aged or warped solenoid diaphragm causing poor sealing
- Faulty control board relay or MOSFET in the valve drive circuit
- Excessive inlet water pressure preventing the valve from closing fully
Self-Check Steps
- Listen for a clicking sound from the solenoid when power is applied
- Remove the valve inlet and inspect the valve core for debris blockage
- Measure the solenoid coil resistance with a multimeter — open circuit indicates coil failure
- Measure the operating voltage at the valve terminals to ensure it is within spec
- Clean or replace the valve inlet screen — disassemble the valve body to remove scale
