FUNCTION ELECTRONIC BOARD ERROR CODES
The function electronic board indicates a series of alarms in case of malfunction of one or more systems, and in case of abnormal
conditions detected in the input signals.
The alarms are shown on the display (71) (except “F6”) by 2 signs following each other: “AL” and “XX”, where XX is the alarm code
(see the descriptions in the following tables).
Also, the alarms are repeated (in case of display malfunction) by the diagnostic LEDs (yellow and red) on the electronic board, as
described in the following tables.
General Alarms (YELLOW LED + RED LED FLASHING)
Alarm Code
= No. of
flashes
Meaning Condition Effect
G2 EEPROM error EEPROM error

G3 General thermal protection Heatsink temperature > 90 °C Function block
G4 Blown F2 fuse V > 1V on F2 Function block
G5 Wrong KEY sequence Wrong key sequence Function block
G6 No signal from BATTERY CHARGER No signal from battery charger
The charging battery phase is not
shown
G7 Undervoltage B+ - B- < THRESHOLD2 for t >10” Function block
G8
Serial communication error with dashboard

Function Alarms (RED LED FLASHING)
Alarm Code
= No. of

F3 VACUUM SYSTEM amperometric protection
Vacuum system abnormal electrical input >
30A for T>10s
Vacuum system block
F4 DECK ACTUATOR position irregularity
End-of-stroke microswitch configuration not
plausible or end-of-stroke not reached within
10”
Deck actuator block
F5 VACUUM SYSTEM power section damage CC MOSFET Vacuum system block
F6 PRESSURE SWITCH signal fault Pressure switch Vout > 4.0V
Water level visualisation missing
+ water flow and % detergent
management fault
F7
VACUUM SYSTEM output short circuit I > 2 * 50A Vacuum system block
F8 Function general relay fault Always closed / opened Function block
All “general” and “function” alarms, and their relevant effects remain until reset from KEY input. In case of simultaneous errors, the
one with greater priority is shown first (priority order is opposite to the number of flashes).
