E71: Washing Ntc Probe Faulty - Electrolux EWM0931 Series Service Manual

E71
Checks to perform:
Run phase 6 of the diagnostic cycle
and wait for the water to fill. Switch
the appliance off and measure the
value of the NTC probe between
contacts J7-4 and J7-5 of the wiring
connector
-see fig. 4-.
Is the value correct?
(between 5.7 - 6.3 KΩ at 20°C)
Y

S
Measure between terminals J7-4,
J7-5 of the NTC connector and the
appliance body – (see fig. 6) -
Is there any dispersion?
Y
E
S
Detach the connector and measure
directly between the terminals of the
NTC probe and the appliance body
(there must be water in the tub).
Has dispersion been measured?

Run phase 8 of the diagnostic cycle,
drain water from the tub. Replace the
washing heating element and repeat
the diagnostic cycle to check for any
further alarms.
