中文
含义
换挡执行器（离合器切换机构）故障，无法在洗涤和脱水模式间切换。
常见原因
换挡执行器线圈烧毁或断路、执行器线束连接不良、机械联动机构卡滞、控制板驱动输出异常。
自助排查
- 断电后手动检查执行器机械运动是否灵活。2. 检查执行器线束插头是否牢固。3. 测量执行器线圈电阻（通常几十欧姆）。4. 机械卡阻需清理润滑，电气故障则更换执行器。
English
Meaning
Shift actuator (clutch mechanism) fault — unable to switch between wash and spin modes.
Common Causes
Actuator coil open or burned, loose actuator harness connection, stuck mechanical linkage, or control board drive output failure.
Self-Check Steps
- Check actuator mechanical movement freely by hand with power off. 2. Verify actuator harness plug is secure. 3. Measure actuator coil resistance (typically tens of ohms). 4. Clean/lubricate if stuck mechanically; replace actuator if electrical.
