6.2 Table of alarm codes
When an abnormal situation occurs that may interfere with machine functioning, the main board activates a safety system which in most cases interrupts the
washing cycle. The last three alarm situations are stored in memory. Using a special procedure, service personnel can display all the alarms stored in memory. The
user is only shown four of the alarms in progress.
The alarms are shown on the display and signalled with "beeps" from the buzzer (only on certain alarms).

Description of ALARM
Water fill time-out
(the pressure switch has not switched to
FULL within 90 sec. of static filling, or
never switches to FULL during the first
60 sec. of dynamic filling at 2800 RPM)
Water drain time-out
(the pressure switch has not returned to
EMPTY after two drain phases lasting
120 sec.)
Intervention of anti-flooding device
(drain pump operates)
Short circuit on motor triac
(wash pump operates continuously at
maximum speed)
Heating time-out
(heating is checked every 3 minutes: the
temperature must increase by a certain
value every time)
32
Status of machine
The drain pump starts and then
the cycle stops
The drain pump starts and then
the cycle stops
The cycle stops and the drain
pump starts.
Water fills to operating level (if
necessary), other mechanical
systems fail to operate and cycle
stops. The washing motor
operates at max. speed and alarm
is displayed.
The programme is fully executed
without heating (and with poor
washing performance)
599 35 94-03
Possible causes
Tap closed; Water mains pressure too low; Drain
solenoid / wiring faulty; Pressure switch on water
circuit plugged; Level pressure switch / wiring
faulty; Faulty circuit board (short circuit on solenoid
triac).
Drain circuit plugged / clogged; Drain pump faulty /
obstructed (foreign bodies); Level pressure switch
stuck on FULL (1-3); Pressure switch on water
circuit plugged; Faulty wiring;
Faulty circuit board.
Water leakage from tub – sump and various
couplings (pumps, line to upper spray arm,etc.);
Floating sensor jammed; Faulty microswitch; Fill
solenoid jammed; Faulty circuit board (short circuit
on solenoid triac). Faulty wiring.
Faulty circuit board
Faulty heating element; Safety thermostats have
tripped (open); Faulty wiring; Faulty NTC sensor
(poor thermal contact); Poor water circulation in
tub; Faulty wash pump (impeller stripped) Faulty
circuit board.
