Water purifier is a multi-stage cartridge for water purification and treatment of water purification equipment, processing more than the use of filtration without the addition of chemicals, adsorption, reverse osmosis and other physical methods. According to the water purifier water purification accuracy can be divided into living drinking water purifier, also known as household water purifier and laboratory water purifier can reach the laboratory pure water quality requirements of the two types of water purifier.
1. Pump does not work to check whether the power outlet is plugged in or the power switch is open. Check whether the high-pressure switch or water level controller is out of order, or the wiring line is loose. Check whether the power adapter is burned, if it is burned, please check whether the RO membrane is blocked and cause the pump overload.
2. Pump leakage check whether the pre-filter cartridge is blocked to the pump water can not be sent out, if so, please replace the cartridge and send the pump for repair. The aging of the rubber membrane of the pump head or internal scale blockage can also cause water leakage, please send the pump for repair, after the repair, you need to diligently review the second and third filter membrane to avoid blockage. Concentrated water proportioner blockage leads to reverse osmosis membrane blockage caused by the pump water can not be sent out of the high pressure water filled with the pump after the leakage, improve the related parts should be able to recover. The fixing screw of the pump head is loose.
3. The pump operates normally but can not make water RO membrane blockage, if the RO membrane blockage, please replace it. Pump failure such as the pump pressure loss, find out whether the long-term heavy load or filter element often blocked without proper maintenance, resulting in the aging of the pump structure, please send repair pump. Water inlet solenoid valve failure can not enter the water, please replace it. (Refer to the full-automatic model) The second pre-filter cartridge is blocked.
4. Pressure bucket full level of pure water can not flow out of the pressure bucket air pressure relief, please re-inflate (0.05MPa or so) and check whether the pressure bucket leakage phenomenon, if you can not inflate the replacement. Pressure bucket internal damage, replacement.
5. The machine is in the stop condition, but the water solenoid valve can't be locked, please disassemble and check whether there is something stuck, or has been a failure, choose the appropriate method to deal with it.
6. The water is full and can not shut down or shut down immediately after the start, the frequency is very fast and can not completely shut down the high-pressure switch failure, can be repaired to repair, can not be repaired to a new one. Backstop valve pressure relief and can not be blocked, please replace it. The system has a pressure relief condition, check whether the components are leaking.
7. The proportion of pure water and concentrated water is seriously out of proportion, the concentrated water proportioner is blocked or too conductive. RO membrane blockage or serious decline in the removal rate.
8. TDS value (conductivity) is high RO membrane removal rate is reduced or even failure. RO membrane tube of pure water and concentrated water end is not strictly separated from the crack phenomenon. Post-activated carbon failure. RO membrane rubber band is too small or broken at one end.
The above briefly introduces you to the common failures of water purifier, so if we have a water purifier installed in our own home, when there is a malfunction, we can roughly determine the failure of the water purifier. Of course, we should pay attention to good maintenance in our normal life, so that we can make the water purifier service life longer.
