PROBLEM
Water is not flowing
from outlet
Leaking or dripping
from outlet
Tap turns on randomly
or erratically
Battery only lasts a
few weeks or days
Sensor red light
constantly blinks
Water stops slowly
Constant flow of
water
Sensor green light
blinks

CAUSE
Water is turned off
Isolation valves are turned off,
or only one supply is turned on
Aerator or flow control is blocked by
debris
Power is turned off while solenoid is
in closed position
Solenoid locked up due to supply
pressure being too high
Water supply failure
Strainers contain debris
Solenoid is blocked by debris
Supply water pressures are too high
Sensor beam interference
by reflections off mirror or
high-visibility vest
Incompatible lighting or electrical
interference in the environment
Sensor has been permanently
damaged due to reversed polarity
(being incorrectly connected)
Low voltage
Battery is running out, or power
supply is insufficient
Solenoid has debris caught
in the mechanism
Solenoid valve is damaged or
solenoid has debris caught in the
mechanism
Electronic component failure -
solenoid valve / sensor / battery /
power supply
Power supply is turned off
Sensor is constantly activated by an
object in front of sensor
Sensor is in Cleaning Mode
RECTIFICATION
Ensure water supply is turned on
Check integral isolation valves are turned
on
Clean, then re-install or replace aerator / flow
control
Turn power supply on and activate sensor
Release water pressure from solenoid,
either by unscrewing the strainer / check valve
assembly, or by unscrewing the solenoid. Sensor
tap should start working again. Install
a Pressure Reduction Valve (PRV) before the tap
to prevent the problem recurring
Restore inlet supply
Clean strainers ensuring debris is removed
Dismantle solenoid, remove debris and clean
Check pressure and install a pressure reduction
valve
Remove interfering object, or adjust sensor range
and / or sensitivity by reprogramming the sensor
(refer to sensor program on page 24.)
Replace sensor and battery. A new battery
typically lasts between 3 to 5 years, depending on
frequency of use
Replace battery
Check if power cable is not pinched or damaged.
Check power supply
Remove solenoid and inspect solenoid membrane
for debris. Remove debris and/or replace solenoid
if damaged. See Service and Maintenance
Remove solenoid and inspect solenoid membrane
for debris. Remove debris and / or replace
solenoid if damaged
Follow steps in Service and Maintenance and
replace if needed
Turn on power supply
Remove interfering object, or adjust sensor
sensitivity by reprogramming the sensor (refer to
sensor program on page 24.)
Sensor is in Cleaning Mode. See Sensor Program
on page 24 for more details.
