Alarm: EP
Low Production
(cylinder OFF)
excessive reduction in steam production,
or excessive foam in the cylinder.
Perform maintenance on the cylinder manual active stop steam
production
Alarm: EF
Lack of water
(cylinder OFF)
no water in the cylinder check that the supply hose and the internal hoses
are not blocked or choked and that there is su cient
pressure (0.1 to 0.8 MPa, 1 to 8 bars);
check the operation of the  ll solenoid valve;
check that the steam outlet is not operating with
excessive backpressure, preventing the  ow of water
into the cylinder by gravity;
check that the steam outlet hose is not choked and that
there are no pockets of condensate

Alarm: EL
Low urrent
(Cylinder OFF)
power not available; when the unit is
activated no steam is produced
with the unit o and disconnected from the mains, check
the electrical connections.

Alarm: EH
High current
(Cylinder OFF)
probable fault in the electrodes or water
temporarily too conductive(especially
when restarting after a short stop)
check the operation of the electric drain pump;
check the seal of the  ll solenoid valve when not
energised; drain some of the water and re-start.

High
conductivity
(Cylinder OFF)
high supply water conductivity check the limit threshold set;
switch the unit o and clean the electrodes that
measure of the conductivity of the water; if the problem
persists, change the origin of the supply water or use a
suitable treatment system (partial demineralisation).
Note: the problem is not resolved by softening the supply
water

Warning:
EA Foam
cylinder
excessive foam in the cylinder during
boiling
the entrainment 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:
drain the water supply lines;
clean the cylinder make sure a softener is not used (if so,
use another source of water or reduce the softening).
