含义
6C表示洗衣机水位传感器（压力传感器）出现故障。水位传感器用于检测洗衣机桶内的水位高度，并将信号发送给主控板以控制进水和排水。当传感器开路、短路或输出异常时，洗衣机无法准确判断水位。
常见原因
- 水位传感器内部膜片老化或破损，导致输出压力信号偏移。
- 传感器连接软管脱落、破裂或堵塞，使传感器无法感受桶内气压变化。
- 传感器连接器氧化或松动，信号传输中断。
- 主控板上水位检测电路元件损坏。
- 传感器受潮或进水，内部电路短路。
自助排查
- 拔掉电源插头，等待一分钟后重新插电，观察故障代码是否消失。
- 检查传感器连接线束插件是否松动或氧化，重新插拔并清洁接触点。
- 拆下洗衣机上盖，找到水位传感器，检查连接软管是否脱落或破损。
- 用万用表测量传感器的电阻值或通断状态（参考维修手册标准值）。
- 若以上检查无效，需更换水位传感器，建议联系售后。
English
Meaning
6C indicates a water level sensor (pressure sensor) fault on the washer. The sensor monitors the water level in the tub and sends the signal to the control board for fill and drain control. An open, shorted, or erratic sensor prevents accurate water level detection.
Common Causes
- Aged or damaged diaphragm inside the water level sensor causing pressure reading drift.
- The sensor hose is detached, cracked, or blocked preventing pressure transmission.
- Oxidized or loose sensor connector causing intermittent signal.
- Damaged water level detection circuit on the main board.
- Moisture ingress into the sensor causing internal short circuit.
Self-Check Steps
- Unplug the washer for one minute, then re-plug and check if the code clears.
- Check the sensor connector for looseness or oxidation — reseat and clean contacts.
- Remove the washer top panel to access the water level sensor and inspect the hose.
- Use a multimeter to measure the sensor resistance or continuity (refer to service manual values).
- Replace the water level sensor if checks are inconclusive — contact Samsung.
