3. Water is sucked back during
steaming, even after having
restored the correct level (as
per Pos. 2).
4. No water in the boiler with
consequent heating elements
burning due to the failure of
the electronic level control
group.
5. No water in the boiler due to a
failure of the water feeding
group (electric valve, tubes
and connections).
6. The pump does not work.

3. Causes:
a) The electric feeding valve is
out of order or dirty, and
prevents the pin from closing
tight, water leaks in.
b) Water is not drained every day
from the boiler, and foam
develops.
c) The boiler level gauge has
lime scales (mostly on its end):
the machine does not operate
correctly and water is fed in
continuously.
d) Interruption on wires and on
connection contacts of the
level gauge on the electric
panel.
e) Electronic group failure.

a) Try to operate the pump rotor
by rotating the motor shaft by
means of a screw driver
applied into the slit on the

the pump cover must be
disassembled, the brass fan
must be cleaned and
correct rotation checked.
