What are the brief maintenance methods of the water purifier

1. The high-voltage pump cannot be started and cannot produce water. Check whether the power is cut and the plug is plugged in; check whether the low-voltage switch is malfunctioning and cannot be connected to the power supply; check whether the high-voltage switch or water level controller malfunctions; check whether the transformer and fuse are burned .
2. After the water is full, the machine repeatedly takes off and the raw water pressure is lacking; the check valve releases the pressure; the high pressure switch fails; the system has a pressure release phenomenon.
3. Lack of clean water flow and blockage of front filter element; lack of pressure of high-pressure pump; blockage of RO membrane; imbalance of wastewater ratio or flushing switch is not closed tightly.

4. The ratio of purified water to wastewater is seriously imbalanced. Check whether the flushing solenoid valve is damaged; check whether the waste water dispenser is blocked or too conductive; check whether the RO membrane is blocked or the removal rate is seriously reduced.
5. The high-pressure pump does not stop. The high-pressure pump has insufficient pressure and cannot reach the set pressure; the check valve is blocked and no pure water is discharged (there is waste water but no pure water). The high-pressure switch fails and cannot be started; the solenoid valve fails and cannot be opened effectively.
6. The high-pressure pump works normally but cannot produce water. The high-pressure pump loses pressure; the front filter element is blocked (no pure water or waste water); the check valve is blocked (there is waste water but no pure water); the solenoid valve fails and cannot be opened effectively ; The RO membrane is not clogged.
7. The machine continuously flushes the waste water than it fails, or the flushing is not tight at the beginning.
8. The high-pressure pump stops but the waste water solenoid valve fails continuously, and the water cannot be effectively shut off; check method: close the pressure barrel ball valve, if there is still waste water, it can be concluded that the solenoid valve is malfunctioning; there is another situation, close the water inlet solenoid valve and open it If the machine is normal, it is concluded that the water pressure is too high, and the solenoid valve cannot be closed flexibly. Then consider adjusting the water inlet pressure below the precipitation pressure; check the pressure of the check valve to relieve the pressure, check the method: close the water inlet solenoid valve, if there is still waste water, then It can be concluded that the check valve is depressurizing.

9. The water in the pressure tank is full but the clean water cannot flow out of the pressure tank to relieve the pressure; the post-installed activated carbon is blocked; is the pressure tank ball valve damaged?
10. If the noise is loud, see if the raw water pipeline is cut off, causing the booster pump to run dry, causing the water purifier to be noisy; check if the raw water is normal, if there is no tower water supply, if there is gas in the water; check if the booster pump is faulty, Excessive sensation, clashes, etc. Check whether the water purifier is stable; check whether the water pipe is too long or the pump sensation makes the water pipe hit the casing to check whether the hot water is jubilant and cause excessive noise; check whether the compressor is normal .
