3. if the problem persists, change the
source of supply water or install a
suitable treatment system
(demineralisation, even partial).
N.B.: the problem will not be resolved
by softening the supply water.

3 slow E114 no water 1. check that the fill pipe from the mains total machine automatic active automatic
flashes to the humidifier and the internal pipe shut- disabled when water when
red are not blocked or bent and that there down returns (see water
LED is sufficient pressure (0.1-0.8 MPa, par. 11.4.10) returns
1-8 bar);
2. check the operation of the fill
electrovalve;
3. check that the steam outlet is not
working against excessive back-pressure,
preventing the flow of water into the
cylinder by gravity;
4. check that the steam outlet pipe is not
is choked and that there are no pockets
of condensate.
not E115 excessive foam in the cylinder the formation of foam is generally due to - signal manual active manual
featured during boiling the presence of surfactants in the water only
(lubricants, solvents, detergents, water
treatment agents, softeners) or an
excessive concentration of dissolved salts:
1. drain the water supply lines
2. clean the cylinder
3. check for the presence of softeners
(in this case, use another type of water
or reduce the softening)
