E9 - 海信 洗衣机

中文

含义

E9 为水位（压力）传感器故障。洗衣机通过气压式水位传感器检测桶内水位，传感器通过导气管感知桶内气压变化。

常见原因

1. 压力开关膜片卡滞
2. 导气管破裂漏气
3. 水位传感器电感线圈开路
4. 传感器输出频率超出正常范围

自助排查

1. 检查水位传感器与桶体的导气管连接是否松脱或破损，如有裂纹需更换。
2. 向传感器导气管一端轻轻吹气（先断开传感器端），检查管路是否通畅。
3. 用万用表频率档测量水位传感器输出频率，空桶和水满时频率应明显不同。
4. 如传感器输出不正常，需更换同型号水位传感器。
5. 水位传感器涉及水位校准，建议联系海信售后更换并校准。

English

Meaning

Water level (pressure) sensor fault. The washer detects the drum water level via an air-pressure water level sensor.

Common Causes

1. Pressure switch diaphragm stuck
2. Air hose cracked and leaking
3. Water level sensor coil open circuit
4. Sensor output frequency out of normal range

Self-Check Steps

1. Check the air hose connection between the water level sensor and drum for looseness or damage; replace if cracked.
2. Gently blow into the sensor end of the air hose (disconnect it first) to check if the tube is clear.
3. Use a multimeter frequency setting to measure the sensor output frequency; it should differ significantly between empty and full drum.
4. If the sensor output is abnormal, replace with the same type of water level sensor.
5. Water level sensors require calibration; contact Hisense service for replacement and calibration.
