There are many kinds of accessories for drinking water equipment. Once there is a problem, it is difficult for the entire drinking water equipment to not work. Therefore, when using drinking water equipment, everyone should pay attention to maintaining them! Below, let's take a look at the common faults and solutions of the high-pressure pump of the pure water machine!

1. The high-pressure pump does not start and cannot produce water

Check whether the power is cut off and the plug is properly inserted; check whether the low-voltage switch is malfunctioning and cannot be connected to the power supply; check whether the high-voltage switch or the water level controller malfunctions; check whether the transformer and fuse are burned.

2. The high-pressure pump works normally but cannot produce water

The high-pressure pump loses pressure; the front filter is blocked (no pure water or waste water or small waste water); the check valve is blocked (there is waste water but no pure water); the solenoid valve fails and cannot be opened effectively; whether the RO membrane is blocked.

3. The high-pressure pump does not stop

The pressure of the high-pressure pump is not enough to 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.

4. The high-pressure pump shuts down but the waste water does not stop

The solenoid valve fails and cannot effectively cut off the water; inspection method: close the pressure bucket ball valve, if there is still waste water, it can be concluded that the solenoid valve is malfunctioning; in another case, close the water inlet solenoid valve and open it. If the machine is normal, the water pressure is determined If it is too high, the solenoid valve cannot be closed flexibly, then consider adjusting the inlet water flow to reduce the water pressure; the check valve releases pressure, (the waste water is very small) (check method: close the inlet solenoid valve, if there is still waste water, it can be determined Relieve pressure for the check valve).
