Miele F1471VI - Manual (Page 27)

The freezer defrosts automatically.
The moisture generated in the
appliance collects in the evaporator. It
is automatically defrosted and
dissipated by the condenser
periodically.
This automatic defrosting system
enables the freezer to remain
permanently ice-free, while ensuring
that the food stored in the freezer stays
frozen.
