Fault phenomenon 1: The switch is turned on, but the R0 host motor does not start
Possible reasons
(1) Fuse blown or wire detached
(2) Insufficient pressure in the water supply pipeline
(3) Control box malfunction
(4) Pump stuck
Countermeasures
(1) Replace the fuse and connect the wire end
(2) Check the waterway, ensure the water supply pressure, and check if the security filter is blocked
(3) Replace and repair the pump
Fault phenomenon 2: The water solenoid valve does not open after the equipment is started
Possible reasons
(1) Wiring disconnection
(2) Internal malfunction of solenoid valve
Countermeasures
(1) Check the wiring
(2) Remove the solenoid valve, repair and replace it
Fault phenomenon 3: The pump is running but cannot reach the customer set pressure and flow rate
Possible reasons
(1) Pump reversal
(2) The security filter cartridge is too dirty
(3) There is air inside the pump
(4) Wear of pump head
Countermeasures
(1) Reconnect the wires
(2) Clean or replace the filter element
(3) Eliminate the air inside the pump
(4) Replace the pump head
Fault phenomenon 4: Electromagnetic valve not closed after flushing
Possible reasons
(1) Electromagnetic valve control components and circuit faults
(2) Mechanical malfunction of solenoid valve
Countermeasures
(1) Replace components or inspect and repair circuits
(2) Repair or replace the solenoid valve
Fault phenomenon 5: Under voltage shutdown
Possible reasons
(1) Insufficient supply of source water
(2) The security filter element is clogged
(3) Improper high-speed pressure can cause under pressure during automatic flushing
Countermeasures
(1) Check if the source water pump and pre-treatment system are working
(2) Clean and replace the filter element
(3) The pressure of the high-speed system reaches the optimal state and is maintained above 20Psi
Fault phenomenon 6: The pressure is sufficient, but the pressure gauge does not display properly
Possible reasons
(1) There is a blockage inside the pressure hose
(2) There is air inside the hose
(3) Pressure gauge malfunction
Countermeasures
(1) Check and unclog the pipeline
(2) Eliminate air
(3) Replace the pressure gauge
Fault phenomenon 7: Excessive pressure difference between the front and rear sections of the membrane
Possible reasons
Membrane fouling and blockage
Countermeasures
Clean or replace according to technical requirements
Fault phenomenon 8: deterioration of water quality
Possible reasons
(1) Membrane fouling and scaling
(2) Membrane joint seal aging
(3) Membrane perforation
Countermeasures
(1) Perform chemical cleaning according to technical requirements
(2) Replace the 0-type sealing ring
(3) Replace the membrane
Fault phenomenon 9: Decrease in pure water production
Possible reasons
(1) Membrane fouling and scaling
(2) Changes in water temperature
Countermeasures
Perform chemical cleaning according to technical requirements
Fault phenomenon 10: R0 host does not produce water after flushing
Possible reasons
(1) Pressure water tank is full
(2) Under voltage state
(3) Electrical malfunction
(4) The inlet solenoid valve is not open
Countermeasures
(1) Check the pure water tank
(2) Check the pre filter material and pressure pump of the source water
(3) Repair or replace control appliances
(4) Check the solenoid valve inlet connector or replace it
