中文
含义
洗衣机加热系统异常，加热继电器加热管或相关电路故障。
常见原因
- 加热管表面结垢严重导致局部过热保护
- 加热继电器触点粘连或断开
- 加热管本身断路或对地短路
- 主控板加热驱动电路损坏
- NTC传感器配合异常导致加热失控
自助排查
- 断开电源用万用表测量加热管两端电阻（正常约数十欧姆）若无穷大则断路
- 测量加热管对地绝缘电阻若接近零则为短路
- 检查继电器是否有烧焦痕迹
- 加热管和继电器更换需拆机操作建议联系售后处理
English
Meaning
The washer heating system is abnormal; heating relay element or related circuit fault detected.
Common Causes
- Heavy scale on heating element causing localized overheat protection
- Heating relay contacts welded or open
- Heating element open-circuit or shorted to ground
- Main board heating drive circuit damaged
- NTC sensor coordination fault causing uncontrolled heating
Self-Check Steps
- Disconnect power measure heating element resistance (normally tens of Ohm); infinite = open circuit
- Measure insulation resistance to ground; near zero = short circuit
- Check relay for scorching marks
- Heating element and relay replacement requires disassembly; contact after-sales
