If extended cooling is activated, the drum temperature is checked
approx. 1 minute before the machine goes into standby mode at the
end of the programme. If the temperature is above 55 °C, the dryer
will carry out cooling until it is below 55 °C.
Changing this setting leads to increased energy consumption.
- Factory default: off
- On
The laundry will be cooled down automatically after the end of the
programme. The automatic cooling phase can be set at a cooler
level for all programmes. This means that the cooling phase is ex-
tended.
Changing this setting leads to increased energy consumption.
The setting can be changed from 40 °C–55 °C.
Factory default: 55 °C
The fan operates intermittently to release laundry that is stuck in
front of the inner drum door. With heat-pump dryers, the fan func-
tion operates intermittently to dry duvets.
The fan is switched on and off at certain intervals.

Service

The tumble dryer's electronic module calculates the degree to which
fluff or detergent residues in the fluff filters and vent ducting are im-
pairing performance. A message to check the contamination ap-
pears. You can decide at what level of fluff this reminder should be
emitted.
If the message appears on the display even though the fluff filter is
clean, the vent ducting is regarded as borderline. Miele recommends
improving the vent ducting. Poor vent ducting will result in longer
programme running times and greater energy consumption.
This reminder, which you can configure, is displayed:
