Checks to perform:
Perform phase 6 of the diagnostic
cycle and wait until the fill ends. Switch
the appliance off and measure the
value of the NTC sensor across
contacts J9-8 and J9-9 dof the wiring
connector.
Is the value correct?
(between 5.7÷6.3KΩ at 20°C)
Measure across terminals J9-9, J9-8 of
the connector and the structure of the
appliance. – (see fig. 6) –
Is there any current leakage?
YES
Detach the connector and measure
directly across the terminals of the NTC
sensor and the structure of the appliance
(there must be water in the tub).
Is there any leakage?
YES
Start phase 8 of the diagnostic cycle, drain
water from the tub. Replace the NTC sensor
and restart the diagnostic cycle to check for
further alarms.

Detach the connector
and measure the NTC

– (see fig. 14) –
Is the value correct?
(5.7÷6.3KΩ at 20°C).
YES
Controllare/sostituire il cablaggio e riavviare il ciclo
diagnostico per verificare ulteriori possibili allarmi.
Replace the circuit board and restart the diagnostic
cycle to check for further alarms.
Check/replace the wiring and restart the diagnostic
cycle to check for further alarms.
