Solution
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 water supply 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.
Decrease the range or eliminate
cause of reflection.
Remove, clean and reinstall.

Problem
No water comes out
of the tap:
Water flow from spout
does not stop:
Water flow diminished.
Indicator
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.
Cause
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 mirror or other 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 back-
check prevents from dropping,
even after water supply pressure
drops under 8 bars.
Debris or scale in diaphragm or
the diaphragm is torn.
1. Sensor is dirty or covered**.
2. Sensor is picking up reflections
from mirror or another object.
Filter or aerator is clogged.
