4 fast fl ashes
EH
1010Hex excess current
over-current at the
electrodes;
probable electrode
malfunction
or water
conductivity temporarily
too high (especially
when starting after a
short stop)
1. check the operation of
the drain pump
2. check the seal of the
fi ll electrovalve when
not energised
3. drain part of the
water and re-start
AUTO yes humidifi cation
stopped
2 fast fl ashes
EP
1020Hex no production
excessive reduction in
production , or cylinder
completely depleted
or water
Perform maintenance
on the cylinder
ESC yes humidifi cation
stopped
4 slow fl ashes
CY
3001Hex cylinder life pre-alarm
the cylinder full limit of
1500 h (default)
perform maintenance and/
or replace the cylinder
ESC
(the alarm is
reactivated
after 50 hrs)
no signal only 7 fast fl ashes
EF 2004Hex no water
Check:
• water supply and fi ll
valve;
• whether the manual
drain is open;
• blockage of the fi lter on
the fi ll solenoid valve;
• whether there is
excessive backpressure in
steam outlet, preventing
the fl ow of water into the
cylinder by gravity;
• that the steam outlet
hose is not choked or
that there are no pockets
of condensate;
• that the power cables
are connected to the
cylinder
automatic
(after 10
minute
waiting time)
yes
(in 10
minute

time)
humidifi cation
stopped for 10
minutes only
3 slow fl ashes
Ed
2008Hex failed drain
check the drain pump and
drain connection
ESC yes humidifi cation
stopped
5 slow fl ashes
CP 3004Hex cylinder being depleted
signal
cylinder life ending,
perform maintenance and/
or replace the cylinder
AUTO no signal only 6 slow fl ashes
CL 3008Hex cylinder depleted signal
cylinder life ended, perform
maintenance and/or
replace the cylinder
AUTO no signal only 10 slow fl ashes
EA
3002Hex foam
excessive foam in the
cylinder during boiling.
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)
ESC no signal only 9 slow fl ashes
E2 3010Hex memory backup fails
internal memory error if the problem persists,
contact the CAREL service
center
-- no signal only 6 fast fl ashes
Mn
1001Hex end of cylinder life
the cylinder has exceeded
the limit of 2000 hours,
replace the cylinder
reset hour
