10.3 Table of alarms and signals
solution
1. check the operation of the drain
electrovalve
2. check the seal of the fill electrovalve
when not energised
3. drain part of the water and re-start
1. with the machine off and disconnected
from the mains, check the internal
electrical connections
1. check limit set for b6;
2. turn the machine off and clean the water
conductivity measuring electrodes;
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.
1. cylinder completely depleted or water
with excessive foam. Perform
maintenance on the cylinder
1. check that the fill pipe from the mains
to the humidifier and the internal pipe
are not blocked or bent and that there
is sufficient pressure (0.1-0.8 MPa,
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.
the formation of foam is generally due to
the presence of surfactants in the water
(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)
check the drain circuits and the correct
operation of the drain electrovalve
check the conductivity of the supply water
if necessary, install a suitable treatment
system N.B.: the problem will not be
resolved by softening the supply water.
check the operation of the probe and the
limit set for parameter P2
check the operation of the probe and the
limit set for parameter P3
check the operation of the outlet
probe
