PROBLEM INDICATOR
CAUSE
SOLUTION
No water
coming
out of the
faucet:
Water flow
from spout
does not
stop:
Water flow
diminished
1.Sensor flashes
continuously when
user’s hands are within
the sensor’s range.
2. Red light in the sensor
does not flash when
user’s hands are within
the sensor’s range.
3. Red light in the sensor
flashes when user’s
hands are within the
sensor’s range.
1. Sensor flashes when
user’s hands are within
the sensor’s range.
2. Red light in the
sensor does not flash
when user’s hands
are within the sensor’s
range
Low battery.
1. Range is too short.
2. Range is too long.
3. Battery is completely used up
4. Unit is in “Security Mode”*
5. Sensor is picking up reflections from
the washbasin or another object.
1. Connectors between the electronic
unit and solenoid are disconnected.
2. Debris or scale in solenoid.
3. The central orifice in the diaphragm
is plugged or the diaphragm is torn
4. The water supply pressure is higher
than 8 bar.
5. The water supply pressure is under
8 bars and yet the pressure in the
faucet’s body is higher. This situation
could be caused by a sudden increase
in the water supply pressure that the
backcheck prevents from dropping,
even after water supply pressure drops
under 8 bars.
Debris or scale in diaphragm
1. Sensor is dirty or covered.**
2. Sensor is picking up reflections from
the washbasin or another object.
Filter or aerator is clogged
Replace battery.
Increase the range.
Decrease the range.
The battery must be replaced.
Eliminate cause of reflection.
Connect the electronic unit
connectors to the solenoid.
Unscrew solenoid, pull out the
plunger and the spring from the
solenoid and clean them. Use
scale remover material if needed.
When replacing the plunger,
please make sure that the spring
is in vertical position.
Clean the orifice or replace
diaphragm.
Reduce the supply water
pressure.
Shut off water supply and
unscrew one of the flexible pipes
in order to reduce the pressure
that blocks the product.
Clean the orifice or replace
diaphragm.
Clean or eliminate case of
interference.
1. Decrease the range or
eliminate cause of reflection.
Remove, clean, re-install
* “Security Mode”: If the sensor is covered for more than 90 sec. the faucet will automatically shut off
water flow. To return to normal operation remove any blockage.
** In this case, the water flow will stop anyway after 90 seconds because of the security time.
