3.6.2 NTC air temperature
The NTC dryer heater (1), condenser outlet
tub (5) control the temperatures for the drying programmes.
3.6.2.1 NTC washing machine tub (5)
The NTCs at the condenser inlet and outlet are used to obtain a better
drying result. If one of the two NTCs fails, the customer does not
receive an error on the display. The appliance continues functioning
"normally" even if the drying time is a little longer.
The NTC washing machine tub (NTCD1) controls the
and the switching on of the condensation water valve:
► Warm spin cycle:
► Cottons/Coloureds:
► Easy care:
NTCD1 defective.
The NTC water heater (4) is used instead of
NTCD1 (5) for monitoring the temperature difference
in the condenser. On account of its lower precision
the safety temperature is reduced from 68 °C to
50 °C. The drying programme is executed without
warm spin cycle!
► Temperature NTC water heater > 50 °C:
If the user stops the drying programme and
selects "Drain/Spin" or "Drain", a cool down is run
before the drain cycle until the air temperature
NTC < 45 °C is reached.
If NTC < 45 °C is not reached within 10', only the
drain cycle is run.
