object..
Increase the range.
Decrease the range.
The battery must be replaced.

sor range.
1. Connectors between the electronic
unit and solenoid are disconnected.

3. The central orifice in the diaphragm is
plugged or the diaphragm is torn.
4. The water supply pressure is higher
than 8 bar.
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.
Water flow from spout
does not stop:
1. Sensor flashes once
when user’s hands are
within the sensor’s range.
2. Red light in the sensor
does not flash (once) when
user’s hands are within the

Debris or scale in diaphragm.
1. Sensor is dirty or covered.
2. Sensor is picking up reflections from
the washbasin or another object.
Clean the orifice or replace diaphragm.
Clean or eliminate case of interference.
Decrease the range or eliminate cause of reflection.
Water flow diminished:
