9 Alarms
In the event that an abnormal situation should occur which might affect the correct operation of the appliance, the circuit board causes a safety system to intervene. In
most cases, this interrupts the washing cycle. The last three alarm conditions are stored in memory.
Using a special procedure available only to Service Engineers, it is possible to read all the alarms stored in memory. However, only four current alarm conditions are
displayed to the user.
The alarms are displayed by the display and with a series of “beeps” from the buzzer (only certain models).

Description of the alarm condition
Machine status
Possible causes
i10
YES
Water fill time-out
(The pressure switch does not close on
FULL after 90 sec. static fill, or never
closes on “FULL” during the initial 60
sec of the dynamic fill at 2800 rpm)
The drain pump switches on, then
the cycle stops
Tap closed; water mains pressure too low; fill
solenoid / wiring faulty; hydraulic circuit of pressure
switch obstructed; level pressure switch / wiring
faulty; circuit board faulty (solenoid triac short-
circuited)
i20
YES
Water drain time-out
(The pressure switch does not return to
EMPTY after two drain phases lasting
120 seconds) (**)
The drain pump switches on, then
the cycle stops
Drain circuit obstructed/blocked; drain pump
interrupted or jammed (foreign bodies); level
pressure switch blocked on FULL (1-3); hydraulic
circuit of pressure switch obstructed; wiring faulty;
circuit board faulty
i30
YES
Intervention of Anti-flooding system
(the drain pump switches on)
The cycle is interrupted and the
drain pump switches on
Water leakage from the tub - sump and various
connections (pump, upper spray arm duct etc.);
floating sensor blocked mechanically; microswitch
faulty; fill solenoid blocked mechanically; circuit
board faulty (solenoid triac short-circuited); wiring
faulty
i50
YES
Motor triac short-circuited
(the washing pump runs uncontrolled at
maximum speed)
Water fill to level (if necessary),
disactivation of the other
actuators, cycle interrupted. The
washing motor runs at maximum
speed and the alarm is displayed.
Circuit board faulty
(**) If inside the appliance there is no water at all (correct drain) but this alarm is displayed, check the heater (possible dispersion) and the anti-interference suppressor.
