含义
洗衣机检测到电机无法正常运转或被卡住，显示 LE 故障代码。LE 代表电机锁定错误（Locked Motor Error），属于严重故障。电机转子被卡死无法自由转动，或霍尔传感器反馈信号异常，导致变频驱动系统无法正常工作。
常见原因
- 电机转子被异物卡住——如硬币、发夹等小物件从滚筒缝隙落入电机腔。
- 电机轴承严重磨损、锈蚀或卡死。
- 电机霍尔传感器（位置检测传感器）故障，导致控制器无法获取转子位置。
- 电机定子绕组短路或断路。
- 变频驱动板（IPM 模块）损坏，无法正确驱动电机。
- 连接电机与控制板的线束松动、接触不良或断线。
自助排查
- 立即关闭洗衣机电源，拔掉插头。不要再尝试启动洗衣机，强行运行可能进一步损坏电机或驱动板。
- 打开机门，用手转动滚筒，感受是否有明显的阻力、异响或卡滞——正常情况下滚筒应能较轻松地转动。
- 如果能明显听到筒内有异物撞击声或滚筒转动阻力大，说明可能有异物卡在滚筒与盛水桶之间，需专业拆卸清理。
- 断开电源后等待 30 分钟，重新插电开机尝试一次——偶尔过载保护会触发此代码，冷却后可能自行恢复。
- 如故障依旧，此问题通常超出用户自行处理范围。请联系 LG 售后服务中心，由专业技师上门检测电机、霍尔传感器和驱动板，更换故障部件。请勿自行拆卸电机组件，存在电击和机械伤害风险。
English
Meaning
The washing machine has detected that the motor is unable to rotate properly or is jammed, displaying the LE error code. LE stands for Locked Motor Error, indicating a critical fault. The motor rotor is seized and cannot turn freely, or the Hall sensor feedback signal is abnormal, preventing the inverter drive system from operating correctly.
Common Causes
- The motor rotor is jammed by foreign objects — small items such as coins or hairpins that fell from the drum into the motor cavity.
- Severely worn, corroded, or seized motor bearings.
- Faulty motor Hall sensor (position detection sensor), preventing the controller from reading rotor position.
- Short or open circuit in the motor stator windings.
- Damaged inverter drive board (IPM module), unable to drive the motor correctly.
- Loose, poorly connected, or broken wiring harness between the motor and the control board.
Self-Check Steps
- Immediately turn off the washing machine and unplug it. Do not attempt to restart — forcing operation may further damage the motor or drive board.
- Open the door and manually rotate the drum by hand. Check for noticeable resistance, abnormal noise, or binding — the drum should rotate relatively freely under normal conditions.
- If you hear an obvious rattling sound or feel significant resistance when turning the drum, a foreign object may be lodged between the drum and the outer tub, requiring professional disassembly for removal.
- After disconnecting power, wait 30 minutes, then plug back in and power on to try once — occasionally, overload protection triggers this code and may reset after cooling.
- If the error persists, this issue is generally beyond user-level repair. Contact LG customer service for a professional technician to inspect the motor, Hall sensor, and drive board on-site, and to replace faulty components. Do not attempt to disassemble the motor assembly yourself — risk of electric shock and mechanical injury.
