One: The high-pressure pump fails to start, preventing water circulation.
1. Check if there is a power outage and if the central water purifier's plug is properly inserted.
2. Check if the low-voltage switch is malfunctioning and unable to connect power.
3. Check if the high-pressure switch or water level controller is malfunctioning.
4、Inspect transformers and fuses for signs of burnout.
Two. High-pressure pump failure during operation.
1、The high-pressure pump's pressure is insufficient, preventing it from reaching the set high-pressure.
2、The check valve is blocked, preventing the flow of pure water.
3、High pressure failure, unable to start.
4、The electromagnetic valve malfunctioned, preventing it from opening effectively.
Three. The water outlet of the water purifier has floating debris.
1、 This may be the protective liquid for the filter (typically found on newly purchased central water purifiers or filters). Simply rinse it off; it is harmless to humans.
2. If you purchase a ultrafiltration central water purifier, it can only filter particulate mud, suspended matter, and other impurities from the water, while retaining calcium and magnesium ions in the water. After heating, these ions combine with carbonate ions in the water to form white precipitates.
Four. The central water purifier is not producing water.
1. Check that the water and power supply are functioning correctly, and ensure that the plug is securely inserted into the outlet, and that all switches and wiring connections are intact and operational.
2. Consider whether the central water filter has not been replaced for an extended period, leading to filter blockage.
3. Check if the water pressure is too low. Low water pressure can result in reduced water flow.
Five. The central water purifier continuously indicates that water replacement is needed.
1. Empty the water tank and refill with fresh water.
2. If the "replace water" message persists after changing the water, it may be because the water tank is not properly positioned. Remove the water tank and re-position it.
Six. The central water purification system is not functioning.
1. Check if there is a power outage and ensure the plug is securely inserted.
2. Inspect low-voltage switch terminals for detachment or malfunction, which may prevent the power contacts from returning to their original position.
3. Check if the connecting wires of all terminal connections in the central water treatment unit have come loose.
4、Check if the water pressure from the municipal water supply is too low, which could cause the low-pressure switch to malfunction.
