E10 - 老板电器 洗碗机

中文

含义

控制板硬件故障。主控板检测到内部关键电路异常（如EEPROM读写错误、主芯片自检失败、电压基准异常等），无法正常运行洗涤程序。

常见原因

1. 主控芯片（MCU）损坏或程序跑飞
2. EEPROM存储器数据损坏或读写异常
3. 主控板供电稳压电路故障（5V/3.3V异常）
4. 板级受潮导致漏电或短路
5. 雷击或电网浪涌损坏主控板
6. 晶振失效导致主芯片无法正常工作

自助排查

1. 断电10分钟以上（彻底释放残余电荷），重新上电观察是否恢复
2. 检查家中电压是否稳定，排除电压异常导致的保护性报错
3. 打开控制盒检查主控板有无明显烧焦、鼓包、电解电容漏液
4. 检查主控板有无进水、受潮痕迹，用吹风机冷风档吹干后重试
5. 以上均无效则主控板硬件损坏，需更换控制板总成并重新配对程序

English

Meaning

Control board hardware failure. The main control board detects an internal critical circuit fault (EEPROM read/write error, MCU self-test failure, abnormal voltage reference, etc.) and cannot execute the wash program.

Common Causes

1. Damaged MCU or program crash
2. Corrupted EEPROM data or read/write failure
3. Faulty voltage regulator circuit on the mainboard (abnormal 5V/3.3V)
4. Moisture ingress causing leakage or short circuits on the board
5. Lightning strike or power surge damaging the mainboard
6. Failed crystal oscillator preventing the MCU from clocking

Self-Check Steps

1. Power off for at least 10 minutes (for full discharge), then restart and check for recovery
2. Verify stable household voltage to rule out protective false alarms
3. Open the control box and inspect the mainboard for burn marks, bulging components, or leaking capacitors
4. Check the board for water ingress or condensation; dry with a hair dryer on cool setting and retry
5. If none of the above resolves the issue, the mainboard is hardware-failed — replace the control board assembly and re-pair the program
