常见原因
- 主滚刷上缠绕了大量头发和纤维,导致滚刷无法正常转动。
- 滚刷轴承处进入异物(硬物、碎屑)卡住。
- 滚刷端盖未安装到位或脱出,滚刷与地面摩擦面卡滞。
- 滚刷电机皮带松弛或断裂。
- 滚刷电机碳刷磨损或电机烧毁。
- 滚刷盖板未正确安装,与滚刷接触过紧。
自助排查
- 取出主滚刷,用随机附带的清洁工具或剪刀清理滚刷上缠绕的头发和线头。
- 清理滚刷两端轴承座内的杂物——用镊子取出卡在轴承座里的碎屑。
- 检查滚刷端盖是否完好——若端盖磨损或脱落需更换。
- 检查滚刷盖板是否安装到位——重新安装确保卡扣扣紧。
- 清理后装回滚刷,开机测试。若 E4 仍存在,主刷电机可能已损坏,联系 TCL 售后更换主刷电机或滚刷组件。
English
Meaning
The main roller brush is stuck or overloaded. E4 indicates abnormal main brush motor current — the roller brush is heavily entangled with hair, jammed by foreign objects, or the motor speed sensor is abnormal.
Common Causes
- Large amounts of hair and fibers wound around the main roller brush, preventing normal rotation.
- Foreign objects (hard debris, particles) lodged in the roller brush bearings.
- The roller brush end cap is not properly installed or has come off, causing the brush to bind against the floor.
- The roller brush motor belt is loose or broken.
- The roller brush motor carbon brushes are worn or the motor is burned out.
- The roller brush cover is not correctly installed, pressing too tightly against the brush.
Self-Check Steps
- Remove the main roller brush and use the included cleaning tool or scissors to remove hair and threads wound around the brush.
- Clean debris from the bearing housings at both ends of the roller brush — use tweezers to extract lodged particles.
- Check that the roller brush end caps are intact — replace if worn or detached.
- Check whether the roller brush cover is properly installed — reseat it and ensure the clips are firmly engaged.
- After cleaning, reinstall the roller brush and power on to test. If E4 persists, the main brush motor may be damaged. Contact TCL after-sales for main brush motor or roller brush assembly replacement.
