SAFETY PROCEDURES
Filling alarm
Consequences
n The heating LED LCH remains off.
n Other LEDs blink rapidly.
Causes
If the level in the hot water / steam boiler is still low after 3 minutes of filling.
n If the level in the hot water / steam boiler is still not reached a minute after hot
water has been drawn. Check is done in the ON and ECO mode.
n
Temperature / coffee alarm
Consequences
n LCH, CAF1, CAF 2 and CAF 3 LEDs blink.
n Supply to the resistance is cut off and the keys CAF1, CAF2 and CAF3 are
disabled.
Cause
If the temperature of the coffee boiler crosses 120°C.
n If, at the end of 3 minutes of switching on the machine, in the normal working
mode, the set temperature is not reached, the machine gives the coffee boiler
temperature alarm.

E
TECHNO
TECHNICAL GUIDE
Temperature / hot water-steam alarm
Consequences
n Rapid blinking of the LCH, LVAP and LTE LEDs.
n Supply to the resistance is cut off and the T.VAP and T.TE keys are disabled.
Cause
n If the temperature of the water / steam boiler crosses 130°C.
n If, at the end of 3 minutes of switching on the machine, in the normal working
mode, the set temperature is not reached, the machine gives the hot water/
steam boiler temperature alarm.
Flowmeter alarm
Consequences
n Blinking of the LED of the selected dose.
Cause
n If he fault arising due to insufficient water or blockage of a flowmeter for 5
seconds is indicated by the blinking of the LED of the selected dose.
After 30 seconds, the dose is disabled and the alarm goes out.
