The table below lists the alarm indications, the causes, the conditions and
the possible solutions.
alarm code cause

(once having tried the suggestion, if the problem persists
, contact the CAREL service department)
action reset alarm relay
Overtemperature
•
the PTC probes
of the heaters
have detected an
overtemperature
•
Klixon activation
•
motor protector
outlet is open
•
check the earth current of the heaters, and replace them, if necessary.
•
manually reset the Klixon
•
problem dependent mainly on operation without water or in the
presence of lime on heater surface;
•
turn the machine off and, once it has cooled down,reactivate the
thermostat on the cylinder cover after having cleaned the cylinder
and the level control, checking the effi
ciency of the components;
•
check that the electrical and water connections are in order and that
the machine is supplied correctly;
•
it may be necessary to replace the PTC sensors if installed
Unavailable
Active if Et

for at least one
minute
Water level
malfunction
fl oat
•
check the correct supply of water to the boiler;
•
turn the machine off and clean: the boiler, the level control and the
fi ll solenoid valve see procedure “AR” manual
Active only
if
EE is displayed
during AR
High conductivity
high conductivity of
the supply water
•
turn the machine off and clean the water conductivity measuring
electrodes;
•
if the problem persists, change the source of the supply water or
install a suitable treatment system (demineralisation, even partial);
•
the problem will not be resolved by softening the supply water
total shutdown automatic active
Autotest
autotest failed;
probable problems in:
water supply,
level control or
solenoid valve
•
ensure that the machine is supplied with water;
•
turn the machine off and clean the level control and the fi ll valve
see procedure
“AR”
manual
Active only on
the second EP or
after the EE
during AR
Steam production
•
electrical power
not available; on
machine start-up no
steam is produced
or the water is not
pre-heated
•
fl oat locked in high
level position.
with the machine off and disconnected from mains power supply,
check that there are no defective of malfunctioning electrical connec-
tions
see procedure
“AR”
manual active
No water
No water
•
check that the supply pipe from the water supply to the humidifi er
and the internal pipe is not blocked or choked and that the pressure
is suffi
cient (0.1...0.8 MPa, 1...8 bar);
•
check the operation of the fi ll solenoid valve;
•
check that the steam supply does not have to work against excessive
back-pressure, preventing the fl ow of water into the boiler due to
gravity;
•
check that the steam supply pipe is not choked or that there are
no pockets of condensation

active
Foam present
formation of foam
in the boiler during
boiling
•
the formation of foam is usually due to the presence of surfactants
in the water (lubricants, solvents, detergents, water treatment or
softening agents) or an excessive concentration of dissolved salts.
Drain the water supply line;
•
clean the boiler

•
check the conductivity of the supply water;
•
if necessary, install a suitable water treatment system;
