TROUBLE – SHOOTING
Low battery.
Inappropriate sensor range.
Battery is completely
used up.
Connectors between
the electronic unit and
the solenoid valve are
disconnected.
Debris or dirt in the solenoid
valve clog up the bleeding
hole.
The water supply pressure
is higher than 8 bars or
pressure peaks over 8 bars
in the water supply causes
pressure to be trapped in
the flush valve.
Replace battery.
Connect the connectors of the
electronic unit to the solenoid
valve.
Increase or decrease the sensor
range.
Replace battery.
Eliminate cause of reflections.
Replace or clean the solenoid
valve.
Unscrew the solenoid, pull out the
