E0
Functional anomaly of the ambient probe,
set in
the variable S9.
Verify the correct configuration of the used
probe (variable S9 and electrical connections
on dedicated clamps).
If the problem persists, replace the probe.

E1
Maximum level of water in the cylinder /
Problems of current reading.
The water inside the cylinder has reached the
maximum level sensor and the absorbed current is
below the minimum threshold of 0.5A.
The achievement of the maximum level combined
with a current measured too low, identifies an
anomaly that does not occur in normal operation.
This alarm blocks the production of steam until it is
acquired (pressing the Silence key).
Check the correct insertion of the cylinder
connector to the humidifier.
Using an amperometric clamp, check the
absorption on the supply phases: one of the
phases may be interrupted.
Check the deterioration of the cylinder
electrodes.
Check that the conductivity of the water is
above the minimum allowed for the type of
cylinder used; in particular, for normal
cylinders it must be greater than 250
S/cm and
for cylinders with low conductivity it must be
greater than 125
S/cm. If so, try reducing the
steam production % by modifying the Pr
variable to lower the water working level in the
cylinder.
Particles in suspension produced by oils or
greases present in the water loading line may
cause foaming that activates the level sensor:
perform some complete washes of the cylinder
with manual water discharge, immediately after
the full load.
A water conductivity above 1300
S/cm may
cause foaming: increase the frequency of
deconcentration discharges by modifying
parameter S2.
Check that there is no water under the circular
cable tray, on the top of the cylinder. This, if
present, could penetrate the circular cable tray
and create a false contact on the level sensor:
dry everything carefully.

Pump discharge test anomaly
(Skipped 5 consecutive tests)
.
During a pump discharge test (performed once every
10 hours of operation) if the maximum level is
reached or the test current It isn't reached within 10
minutes, the test is interrupted and considered
SKIPPED.
After the consecutive skip of 5 tests the error E1 is
activated and the steam production is blocked until
the alarm is acquired (pressing the Silence key).
Use the same operations as indicated for the E1
error described above.

E2
Functional anomaly of the humidity probe in air
duct,
set in variable S9.
Verify the correct configuration of the used
probe (variable S9 and electrical connections
on dedicated clamps).
If the problem persists, replace the probe.
automatic
E3
Lack of water for a prolonged time.
When S2>=10 and the water loading solenoid valve
remains active for a time equal to (S2 minus 1
minute), the alarm E3 is activated.
If S2 < 10 the alarm E3 is deactivated.
This alarm blocks steam production.
To reset the alarm, you need to enter and exit the
stand-by.
Check that the mains water line is active.
Verify that there is no water leak due to a
break.
Verify that the water loading solenoid valve is
not faulty or disconnected.
