(*) If it is impossible to access the diagnostic mode, turn off and then turn on the machine to see whether a temporary block has occurred. Before replacing the circuit
board, make sure it is receiving power. Check the following:
The continuity of the power cable, the operation of the radio interference filter, the (closed) condition of the contacts on the door interlock switch, the continuity
between connectors A2 / B1 on the board and the radio interference filter.

Description of ALARM
Short circuited or open NTC sensor
Communication error between
microprocessor and EEPROM
Improper software configuration
Problem with turbidity detection
(if so equipped: calibration timeout)
Problem with washing motor: no
signal from tachometric generator
(wash pump operates, but there is no
signal from the generator)
Water additions time-out
(3 times length of S.T. time-out)
No alarm has been stored.

Status of machine
The programme is fully executed
without heating (and with poor
washing performance)
Machine controls inoperative. (*)
Machine controls inoperative
when unit is turned on. (*)
The programme runs as though a
"very dirty" situation were
detected
Disconnect the heating element; if
the problem persists after timeout,
the wash pump will operate at
max. speed and an alarm is
recorded (the cycle continues)
The cycle continues until the next
phase with no added water and
no heating . The fault is corrected
after a drainage phase is
completed.

Possible causes
Faulty NTC sensor; Short circuit / open circuit in
wiring; Faulty circuit board.
Faulty circuit board
Faulty circuit board
(Improper software configuration).
Faulty turbidity sensor; Faulty wiring to sensor;
Faulty circuit board.
Motor winding open / short-circuited; Motor jammed
(foreign bodies); Faulty wiring to washing motor;
Faulty motor capacitor; Tachometric generator
open / short-circuited; Faulty circuit board.
Dishes overturned; Main filter clogged; Excessive
foam; Poor seal on coupling between sump and
pressure switch;
Faulty pressure switch / poor connections;
Domestic drain outlet improperly positioned (siphon
effect, see 5.10.1).
