5C - 三星 洗衣机

中文

含义

5C表示洗衣机检测到水位超过安全上限，溢水保护功能被触发。洗衣机内部水位传感器监测到水位异常升高，控制系统立即切断进水阀并启动排水泵以防止水溢出机外。

常见原因

1. 进水阀内部机械故障导致阀芯无法完全关闭，即使控制板已断电仍有水持续流入。
2. 水位传感器（压力开关）软管脱落、破损或内部膜片损坏，无法正确感知桶内水位。
3. 水位传感器连接线束接触不良或断路，导致控制板收到错误的水位信号。
4. 主控板水位检测电路故障，误判为高水位状态。
5. 排水管路堵塞导致排水不畅，洗涤过程中水位逐渐升高直至触发保护。

自助排查

1. 立即关闭水龙头以阻止继续进水，拔掉电源插头确保安全。
2. 打开洗衣机前下方面板，找到残渣过滤器，清理排水泵内的杂物，然后手动排水。
3. 检查水位传感器连接软管是否脱落或被挤压，重新插好或更换软管。
4. 清理完毕后重新接通电源，关闭机门，选择一个脱水程序运行，观察排水是否正常。
5. 若故障仍然存在，请联系三星售后更换进水阀或水位传感器。

English

Meaning

5C indicates the washer detected water exceeding the maximum safe level and the overfill protection has been triggered. The water level sensor detected an abnormally high water level, so the control board immediately cut power to the inlet valve and activated the drain pump to prevent overflow.

Common Causes

1. The inlet valve has a mechanical fault preventing it from fully closing — water continues flowing even when power is cut.
2. The water level sensor (pressure switch) hose is detached, damaged, or the diaphragm is faulty.
3. Loose or broken wiring to the water level sensor causes incorrect readings.
4. Faulty water level detection circuit on the main board.
5. Blocked drain line causing gradual water buildup until protection is triggered.

Self-Check Steps

1. Turn off the water tap immediately to stop inflow, then unplug the washer.
2. Open the lower front panel, clean the debris filter, and manually drain the tub.
3. Check the water level sensor hose for kinking, detachment, or damage.
4. After cleaning, close the door and run a spin-only cycle to verify drainage.
5. If the error persists, contact Samsung to replace the inlet valve or water level sensor.
