含义
洗衣机进水超时，显示屏显示 ERR4 故障代码。ERR4 表示进水异常，在设定的进水时间内，水位未能达到预设的水位档位，机器判定进水故障并停止运行。
常见原因
- 水龙头未打开或未完全打开。
- 家庭供水压力不足（水压过低）。
- 进水阀过滤网被泥沙、铁锈、水垢堵塞，水流受阻。
- 进水管弯折、扭曲或受到挤压。
- 进水电磁阀线圈烧毁或阀芯卡死，无法正常开启。
- 水位传感器（水位开关）故障或导气管脱落、漏气，导致水位检测失准。
自助排查
- 检查与水龙头连接的水龙头是否完全打开。
- 关掉水龙头，将进水管从水龙头端（或洗衣机进水阀端）旋下，取出进水口处的小过滤网，在水流下刷洗干净后装回。
- 沿进水管从水龙头到洗衣机进水口检查，确保管路没有弯折或压扁，如有则理顺。
- 打开家中其他水龙头检查水压：若全屋水压偏低，建议联系物业或供水公司改善；若仅洗衣机进水慢，请检查进水管是否有堵塞。
- 重新接通水源，启动洗衣机运行一个短程序观察进水状况。
- 如果水压正常且过滤网已清理但进水仍然缓慢或不进水，可能是进水阀或水位传感器故障，请联系海尔售后服务热线 400-699-9999 进行检修。
English
Meaning
The washing machine has experienced a water inlet timeout, displaying the ERR4 error code. ERR4 indicates a water inlet abnormality — the water level failed to reach the preset level within the allotted fill time, and the machine has stopped operation as a result.
Common Causes
- The water tap is not turned on or not fully opened.
- Insufficient household water supply pressure.
- The inlet valve filter screen is clogged with sediment, rust, or scale, obstructing water flow.
- The inlet hose is kinked, twisted, or compressed.
- The inlet solenoid valve coil is burnt out or the valve core is stuck, unable to open properly.
- The water level sensor (pressure switch) is faulty, or the air tube is detached or leaking, causing inaccurate water level detection.
Self-Check Steps
- Confirm that the water tap connected to the machine is fully open.
- Turn off the tap, unscrew the inlet hose from the tap end (or the machine’s inlet valve end), remove the small filter screen at the inlet, scrub it clean under running water, and reinstall it.
- Trace the inlet hose from the tap to the machine’s inlet port, ensuring there are no kinks or crushing; straighten if necessary.
- Test other faucets in the house: if water pressure is low throughout, contact property management or the water utility; if only the washing machine has slow flow, check the inlet hose for blockages.
- Restore the water supply and run a short cycle to observe the water intake.
- If water pressure is normal and the filter is clean but water intake remains slow or absent, the inlet valve or water level sensor may be faulty. Contact Haier after-sales support at 400-699-9999 for repair.
