3. Causes:
even
a) The electric feeding valve
is out of order or dirty, and
(as
per
prevents
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 connection contacts of
the
electric panel.
e) Electronic group failure.
