Fault Check
Before fault checking:
please make sure the installation distance is adequate and correct by referring to the Pre
-
installation instructions.
The LED indicator will light up twice and then stop once after the batteries are installed. To confirm the sensor is work-
ing, place your hand within the sensing range and check that the LED indicators lights once.
Problem
The faucet has no water flow and there is no LED indicator light when within the sensing range
Cause
The batteries are not supplying electricity to the sensor.
Solution 1
Confirm the batteries have been correctly installed. Check that the positive pole is connected to
“+”
mark on
the plastic battery box. Check that the negative pole is connected to
“
-
“
mark on the plastic battery box. Con-
firm the batteries are the correct size as per this manual and have not been forced.
Solution 2
If the LED indicator does not light up and power is confirmed, replace the sensor control module.
Problem
The faucet has no water flow and there is a LED indicator light when within the sensing range
Cause 1
Inadequate electricity supply.
Solution
Place hands under the sensing range for >5 seconds. If the LED indicator blinks every 1.5 seconds there is in-
adequate electricity.
Cause 2
Solenoid valve components are defective.
Solution
The LED indicator should spark for 2 seconds and then turn off. Place your hands within the sensing range, if
the LED indicator lights up once but you can not hear the audible

noid valve,
please check the connections between the sensor control model and solenoid valve. If the connections are
good, change the solenoid valve components.
Problem
The faucet has low water flow
Cause
Low water pressure or water supply stop(s) are partially closed.
Solution
Refer to installation step
3
—at this point, increase water pressure and open the water supply stop (s) fully.
Problem
The faucet has water flow but does not close completely
Cause 1
The solenoid valve is blocked by debris.
Solution
Disassemble the solenoid valve and clean it. Flush pipes and ensure water supply is free of debris. Change the
solenoid valve components if the problem is not solved.
Cause 2
Low water pressure.
Solution
Increase water pressure.
Problem
The faucet has water flow but will not stop running
Cause
Please confirm adequate electricity supply and solenoid valve connections.
Solution
If the problem persists, check that the sensing range is adequate i.e. installed above the washbasin no less
than 25cm. Check that the basin surface is not stainless steel or reflective.
