Connector between the
electronic unit and the
solenoid are disconnected.
Debris or scale in solenoid.
The central orifice in the
diaphragm is blocked or the
diaphragm is torn.
The water supply pressure is
higher than 8 bar.
The water supply pressure is
under 8 bar and yet the
pressure in the tap’s body is
higher.
This situation could be caused
by a sudden increase in water
supply pressure that the check
valve or double check valve
prevents from dropping, even
after the water supply pressure
falls below 8 bar.
Connect the electronic unit’s
connector to the solenoid.
Unscrew solenoid, pull out
the plunger and the spring
from the solenoid and clean
them. Use scale removal
agent if required. When
replacing the plunger,
please ensure that the spring
is in the vertical position.
Clean the orifice or replace
the diaphragm.
Reduce the water supply
pressure.
Shut off the water supply
and unscrew one of the
flexible pipes in order to
release the entrapped
pressure.
Water flow from the
spout does not stop.
