E71: Ntc Washing Sensor Faulty - Electrolux EWM1100 Service Manual

E71
Tests to be performed:
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
-see fig. 4-.
Is the value correct?
(between 5.7÷6.3 KΩ 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?
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?
Replace the NTC sensor and restart the
diagnostic cycle to check for further
alarm conditions.
