含义
增压泵故障。净水器水泵不工作、噪音异常或无法建立足够的管路压力，制水停止或出水量极低。
常见原因
- 增压泵电机碳刷磨损或绕组烧毁——长期高负荷运行
- 增压泵启动电容容量衰减导致无法启动
- 泵头内部密封件磨损导致压力泄漏
- 低压开关故障导致泵无法触发启动
- 增压泵进水口被异物堵塞
自助排查
- 听水泵是否有”嗡嗡”声但不运转——检查启动电容
- 检查进水三通球阀是否完全打开
- 确认低压开关是否正常——进水压力不足时泵不启动
- 清洁泵前过滤网——前置杂质堵塞
- 若泵运转但水压极低——需要换水泵泵头或整泵
English
Meaning
Booster pump failure. The water purifier’s pump does not run, makes abnormal noise, or fails to build adequate pressure — water production stops or output is minimal.
Common Causes
- Worn pump motor carbon brushes or burnt windings from prolonged high-load operation
- Degraded start capacitor preventing the pump motor from starting
- Worn internal pump head seals causing pressure loss
- Faulty low-pressure switch not triggering pump activation
- Blocked pump inlet due to debris or sediment accumulation
Self-Check Steps
- Listen for a humming sound without rotation — check the start capacitor
- Verify the inlet three-way ball valve is fully open
- Confirm the low-pressure switch is functioning — the pump will not start if inlet pressure is too low
- Clean the pre-pump sediment screen — debris at the intake can block flow
- If the pump runs but pressure is very low, replace the pump head or the entire pump assembly
