Checks to perform:
E62: Overheating during washing
E62
The temperature of the NTC probe exceeds 88 °C for more than 5 mins.
E62
Measure the NTC probe
between terminals J10-4
and J10-5 of the main circuit
board connector. Is the
value correct? (between 5.7
and 6.3 k Ω at 20 °C)
Run the diagnostic cycle
and fill with water up to the
door level to make sure the
heating element is
completely submerged.
Measure between the wiring
connector J3-1/J3-2 and the
appliance body.
-(See fig.6)-
Is the circuit open?
Detach the connector and
measure between the
heating element and the
earth contact. -(See fig.19)-
Is the circuit open?
Replace the heating
element and repeat the
diagnostic cycle to check
for any further alarms.
Check/replace the wiring and repeat the diagnostic cycle to check
for any further alarms.
Detach the connector and
measure the value directly
on the NTC probe.
-(See fig.18)- Is the value
correct? (between 5.7 and
6.3 k Ω at 20 °C)
Replace the heating
element and repeat the
diagnostic cycle to check
for any further alarms.
Replace the circuit board
