How to judge whether there are problems with the valve of the filter

After the filter is turned on and the water is turned on, the water outlet does not come out, and the sewage outlet continues to discharge water. You can check from the following aspects:

1. At this time, please check whether the solenoid valve of the equipment is in the "open" state. Normally it should be in the "auto" gear. If the gear is correct, please go to the next step

2. Check whether the controller shows that it is backwashing. If it is backwashing, "F01" will appear on the display screen. If there is no backwashing mark, then further judge whether there is a problem with the solenoid head or the three-way valve.

3. First judge whether the solenoid valve is damaged, turn off the water source, power off the controller, and confirm that the switches on the solenoid valve are all in the AUTO position, and then pull out the hose connecting the solenoid valve to the three-way valve. The hose on the three-way valve of each unit must be pulled out, and then the water does not need to be energized. At this time, observe whether there is water coming out of the hose. If there is water coming out of the solenoid valve hose of any unit, it proves that the solenoid valve has a problem and needs to be replaced

4. If there is no problem with all unit solenoid valves in the third step, and the water still flows out from the sewage outlet, then judge whether there is a problem with the three-way valve. At this time, we do not need to insert the hose back into the three-way valve. Then make a judgment, turn off the water inlet first, then disassemble the hoops of the sewage pipe connected to the three-way valve, directly remove the sewage pipe first, and expose the sewage outlet of the three-way valve directly, and then put it on Open the water source, and the pressure rises to 0.2mpa. Observe whether there is water coming out of the sewage outlet of any three-way valve. If so, it proves that there is a problem with the modified sewage valve and needs to be replaced.

The above four steps can accurately determine whether there is a problem with the solenoid valve and the three-way valve.
