VERIFICATION OF ALARM CODES
In order to facilitate identification of an ALARM CONDITION indicated on the control panel and which
causes one of the safety features to intervene, the possible causes for each alarm condition are listed in
the table below together with suggested solutions.
Note: The control board is unlikely to be the cause of an alarm condition, and should therefore be
checked last.
ALARMS
[A L 1]
[A L 2]
[A L 3]
[A L 4]
[A L 5]
[A L 6]
[A L 7]
[A L 8]
When in an alarm condition, the dishwasher remains inoperative, and does not perform any
function.
To reset the alarm condition, press Sw0 to switch off the appliance.
When the appliance is switched on again:-
After alarm conditions marked with an asterisk (*), the cycle is CANCELLED, and will
restart from the beginning.
After other alarm conditions, the cycle is SUSPENDED, and will resume from the point of
interruption.
SAFETY DEVICE
"NTC" SENSOR
SHORT-CIRCUITED
Range < 450 Ω
"NTC" SENSOR
OPEN-CIRCUITED
Range > 26,700 Ω
WATER HEATING
TIME-OUT
Water does not reach correct
temperature within 45 minutes after
the heating element switches
On
*INTERVENTION OF
ANTI-FLOODING
DEVICE
WATER FILL TIME-OUT
Correct level not reached.
The pressure switch does not switch
to "FULL" (1-3) within 4 minutes
after the solenoid is energised
*PRESSURE SWITCH ON
"EMPTY" (1-2)
After correct level is reached, the
pressure
switch
returns
"EMPTY" (1-2) and does not return
to "FULL" (1-3) within 90 seconds
WATER DRAIN
TIME-OUT
MOTOR INOPERATIVE
MOTOR TRIAC
SHORT-CIRCUITED
POSSIBLE CAUSES
a) Temperature sensor faulty (short-circuited)
b) Wiring short-circuited
c) Temperature too high (>90°C)
a) Temperature sensor faulty (open)
b) Wiring open circuit/disconnected
c) Temperature too low (< -10°C)
a) Heating element open circuit
b) Safety thermostat open
c) Wiring open circuit/loose
d) NTC sensor incorrectly positioned/Poor
thermal contact
e) Insufficient water circulation
f) Motor faulty (pumps/washing impeller)
g) Central filter clogged
a) Water leakage from various couplings
b) Water leakage from motor (sealing ring, shaft
capsule etc.)
c) Floating sensor jammed
d) Float micro-switch faulty
a) Tap closed
b) Fill hose kinked/intervention of Aqua-stop
device
c) Water mains pressure <30 kPa (4 PSI)
d) Intervention of ANTI-OVERFLOW device
e) Fill solenoid/connections opeb circuit
f) Pressure switch faulty/false contacts
g) Obstruction or leakage in IWMS-pressure
switch tube
h) Central filter clogged
to
i) Excessive foam
j) Dishes upside down
k) Siphon created in drain hose
a) Domestic drain outlet unsuitable (obstructed)
b) Motor faulty (pumps/drain impeller)
c) Pressure switch faulty (jammed on 1-3)
d) IWMS - Pressure switch tube obstructed
e) IWMS – sump breather tube obstructed
f) Control board (Relay faulty)
a) Motor winding short-circuited
b) Capacitor open/short-circuited
c) Electrical connections broken/detached
d) Motor jammed by foreign bodies
e) Tachimetric sensor open/short-circuited
a) Control board (Triac short-circuited)
