Error code
Possible Reasons
troubleshooting
Err1 Load short circuit
A conductive metal is embedded in the
titanium plates
Cut off the power supply, remove the chlorine
generator and rinse the titanium plate
There is a short circuit of water inlet at the
connection of titanium plates
Check whether the wiring position of titanium
plate is flooded or burnt out. If not drain out of
water, re-install and start the equipment
Err2 Load break
Very low salinity, no current or very little
current
Add a small amount of salt water to the cells and
restart the chlorine generator
The wire connecting the titanium plate fall
off
Cut off the power supply, remove the chlorine
generator, and check whether the titanium plate
wiring is off
The titanium plate is very old
Change electrolytic cell
Err3
Salinity is higher than the maximum limit
specified
Change part of the pool water to reduce salinity
Err4
Salinity is lower than the maximum lim it
specified
Err5,Water Temperature
light on
The water temperature detected is
exceeded 11℃˜45℃（51˜113F）, will re-work
again when the water temperature is
between 13℃˜43℃（55˜109F）
- Ensure the water temperature is recovered and
restart the chlorine generator
- Check whether the flow switch circuit is broken
NO FLOW
Insufficient water flow, the cavity is filled
with air, and the flow switch is not turned
on
- Ensure the filter pump is operating and that there
are no obstructions or restrictions in the piping
- Increase the flow of filter pump
- Expel air from the cells, ensuring that the water
surface exceeds 2/3 of the cells
The filter is in backwash status
Adjust filter operation status
Disconnection of the flow switch circuit or
other fault
Replace the flow switch
LED display screen does
not display
Display screen damaged
- Check that the power cord of the control box is
plugged into a protected socket - make sure that
the chlorine generator is working properly
- Replace the chlorine generator controller box
- Add salt to the pool
- Expel air from the cells, ensuring that the water
surface exceeds 2/3 of the cells
