Water distribution pressure must be:
version
between
standard
0.05 and 0.85 MPa (0.5 - 8.5
bar).
plus
0.12 and 0.85 MPa (1.2 - 8.5
bar).
Run the water from the mains until it is clear
and dirt free.
Connect the water mains to the 3/4” fitting
of the water inlet solenoid valve via a food
grade pipe (also available as a kit) that is
suitable for withstanding the water mains
pressure (minimum internal diameter of 6
mm).
Installing a tap on the water mains out-
side the appliance and in an accessible
position, is recommended.
Only use new seal and pipe sets and do
not reuse any existing materials.

Only for standard version.
The water inlet solenoid valve is equipped
with an overflow device which mechanically
prevents water from entering if the solenoid
valve or the water level control mechanism
malfunction.
To restore normal operation, proceed as
follows:
1. drain the water in the overflow pipe;
2. shut off the appliance external water
mains tap;
3. loosen the fitting which secures the so-
lenoid valve feed pipe in order to relieve
the residual mains water pressure, and
tighten it again;
4. open the tap and supply power to the
appliance.
