9.4 TABLE 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.

Press ( ) to switch the dishwasher off.
The cycle resumes from the point at which it was interrupted.
The cycle is completed, and no alarm is displayed to the user; the
condition is simply stored in memory for inspection by service engineers.
POSSIBLE CAUSES

b) Mains water pressure <3 bar.
c) The anti-flooding device has intervened.
d) Fill solenoid/connections disconnected.
e) Pressure switch faulty/Loose connections.
f) Obstructions / Leakage from the tube connecting the
sump to the pressure switch.
g) Central filter clogged.

i) Dishes upside-down.
j) Siphon effect in drain hose.
a) Domestic drain unsuitable (blocked)
b) Drain pump/ Connections interrupted
c) Pressure switch faulty (blocked on 1-3)
d) Obstruction in connection between sump and
pressure switch
e) Control board (relay interrupted)
a) Leakage from the various connections
b) Floating sensor blocked mechanically
c) Float microswitch faulty
a) Heating element interrupted
b) Safety thermostat open
c) Electrical connections interrupted / loose
d) NTC sensor faulty / Poor thermal contact
e) Insufficient water circulation in tub
f) Washing pump (damaged impeller)
a) Temperature sensor faulty (short-circuited)
b) Electrical connections short-circuited
c) Temperature too high (>90°C)
a) Temperature sensor faulty (open)
b) Electrical connections interrupted/disconnected
c) Temperature too low (< -10ºC )
a) Motor winding interrupted/short-circuited
b) Electrical connections loose / interrupted
c) Motor jammed (foreign bodies)
d) Capacitor interrupted/short-circuited
e) Tachymetric sensor interrupted/short-circuited
a) Control board (Triac short-circuited)
