E12 - 戴森 吸尘器

中文

含义

机器与LED光环指示环之间的通讯异常，指示灯显示可能不准确或完全不工作，但机器吸尘功能通常不受影响。

常见原因

1. LED光环的连接排线松动或接触不良
2. 光环电路板受潮或进水导致局部短路
3. LED灯珠损坏导致电流异常，影响通讯信号
4. 排线在频繁拆卸集尘桶时被拉扯损伤
5. 控制板与光环之间的数据传输线路受电磁干扰

自助排查

1. 取下集尘桶，检查LED光环的连接排线是否插紧且无断裂
2. 用干布擦拭排线金手指，去除氧化层后重新插紧
3. 将机器放置干燥通风处24小时去除内部潮气
4. 观察光环是否部分亮起——单个灯珠损坏一般不影响使用
5. 若整环不亮且排线完好，可能需要更换LED光环总成

English

Meaning

Communication between the machine and the LED ring indicator is abnormal. The LED display may be inaccurate or completely off, but vacuum suction is typically unaffected.

Common Causes

1. Loose or poor contact in the LED ring ribbon cable connection
2. Moisture ingress or liquid exposure causing partial short on the LED ring PCB
3. Damaged LED bead drawing abnormal current and disrupting the communication signal
4. Ribbon cable damaged by repeated dust bin removal and reinstallation
5. Electromagnetic interference on the data line between the control board and the LED ring

Self-Check Steps

1. Remove the dust bin and check that the LED ring ribbon cable is firmly seated and free of breaks
2. Wipe the ribbon cable gold contacts with a dry cloth to remove oxidation, then reseat
3. Place the machine in a dry, ventilated area for 24 hours to remove internal moisture
4. Observe whether part of the LED ring lights up — a single bad LED usually does not impact functionality
5. If the entire ring is dark and the ribbon cable appears intact, the LED ring assembly may need replacement
