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

Alarm: EF
Lack of water
(cylinder OFF)
no water in the cylinder check that the supply hose and the internal 1.
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;2.
check that the steam outlet is not operating 3.
with excessive backpressure, preventing the
 ow of water into the cylinder by gravity;
check that the steam outlet hose is not choked 4.

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;1.
check the seal of the  ll solenoid valve when 2.
not energised; drain some of the water and
re-start.

(Cylinder OFF)
high supply water conductivity check the limit threshold set;1.
switch the unit o and clean the electrodes 2.
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

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;1.
clean the cylinder make sure a softener is not 2.
