Common failures of water purifiers and their solutions?

1、 The high-pressure pump of the water purifier does not start and cannot generate water
1. Check whether the power is cut off and whether the plug is plugged in.
2. Check whether the low-voltage switch is malfunctioning and cannot be connected to the power supply.
3. Check whether the water pump and transformer are short-circuited or the wiring of the entire machine is incorrectly connected.
4. Check whether the high pressure switch or water level controller fails and cannot be reset.
5. Check whether the computer box is faulty (referring to microcomputer type).
2、 The high-pressure pump of the water purifier works normally, but cannot produce water
1. The high-pressure pump loses pressure.
2. The water inlet solenoid valve is faulty and cannot be fed (there is no pure water or wastewater) (whether it is connected reversely or not).
3. The pre filter element is clogged (there is no pure water or little wastewater).
4. The check valve fails (with wastewater or without pure water).
5. The automatic flushing solenoid valve fails and cannot be effectively closed (it has been in the flushing state).
6. There is a problem with the computer box and the backwash solenoid valve cannot be turned off (it is always in the flushing state).
7. RO membrane clogged.
3、 The high-pressure pump of the water purifier does not stop all the time
1. The high-pressure pump pressure is insufficient to reach the high-pressure set pressure.
2. The check valve is blocked and pure water cannot be discharged.
3. High voltage failure, unable to take off
5. The solenoid valve fails and cannot be opened effectively
4、 The high-pressure pump of the water purifier stops, but the wastewater does not stop
1. The solenoid valve fails and cannot effectively cut off water.
2. There is a problem with the computer box and the solenoid valve cannot be turned off.
3. The intake solenoid valve is not tightly closed or installed reversely. The return of water from the check valve causes the wastewater to flow continuously, and the wastewater that can flow away is different in two situations: the former is tap water, and the latter is pure water. The water quality is different, and the water quantity is different. The former type is relatively flush, while the latter type has a small flow rate. Due to the non-stop waste water caused by the check valve, the ball valve of the water storage tank can be closed, and the waste water flow can be judged to be stopped.
4. The solenoid valve fails and cannot effectively cut off water. (Inspection method: Close the pressure bucket ball valve. If there is still wastewater, it can be determined that the solenoid valve is malfunctioning.).
5. In another case, close the water inlet solenoid valve and then open it. If the machine is normal, it is judged that the water pressure is too high, causing the solenoid valve to not be flexibly closed. Therefore, consider adjusting the water inlet valve to reduce the water pressure.
6. Check valve pressure relief, waste water is very small, inspection method: Close the intake solenoid valve, if there is still waste water, it can be determined as check valve pressure relief.
5、 After the water is full, the water purifier repeatedly jumps, with a faster frequency and cannot be completely stopped
1. Insufficient raw water pressure.
2. Please replace the check valve for pressure relief.
3. High pressure switch or liquid level switch fails.
4. If there is pressure relief in the system, check whether each component leaks water.
6、 The pressure bucket of the water purifier is full, but pure water cannot flow out
1. The pressure in the pressure bucket is discharged.
2. The rear activated carbon is blocked.
3. Check whether the pressure bucket ball valve is damaged.
7、 Insufficient pure water flow of water purifier
1. The first three filter elements are blocked.
2. The high-pressure pump pressure is insufficient.
3. RO membrane clogged.
4. The wastewater ratio is misadjusted or the wastewater valve is not closed tightly.
5. The rear activated carbon is blocked.
6. Insufficient pressure or internal damage in the pressure bucket.
7. The water temperature is too low.
8. The raw water pressure is too low.
8、 What is the reason for water leakage near the pipe interface of the water purifier?
1. Check whether the PE pipe head is cut flat.
2. Check that the pipe plug is plugged in place.
3. Check whether the screw cap is tightened.
9、 What is the reason for abnormal noise during the operation of the water purifier?
1. Check whether the check valve is malfunctioning or aging.
2. Check if there is a problem with the quality of the booster pump.
10、 What is the reason why the daily water yield of the water purifier cannot meet the requirements?
1. Check whether there is an error in the calculation.
2. Check whether the water pump pressure is in place.
3. Check whether the waste water valve or waste water proportioner is excessively conductive.
4. Check if the water temperature is too low.
