中文
含义
进水时间过长，未能达到设定水位（与F8E1类似但常与水位检测相关）。
常见原因
水压过低、进水阀部分堵塞、水位传感器/压力管漏气导致误判、进水阀流量不足。
自助排查
- 检查水压是否正常（打开水龙头观察流量）。2. 清洁进水阀滤网。3. 检查水位压力管是否脱落或破损。4. 听进水阀有无嗡嗡工作声，无声则需更换。
English
Meaning
Filling time too long — the washer did not reach the target water level within the expected period.
Common Causes
Low water pressure, partially clogged inlet valve, leaking pressure hose or faulty pressure sensor causing false level reading, or reduced valve flow rate.
Self-Check Steps
- Check water pressure by observing faucet flow rate. 2. Clean inlet valve screens. 3. Inspect pressure hose for leaks or disconnection. 4. Listen for inlet valve hum; replace valve if silent but powered.
