What types of laundry should not be dried in this machine?

Do not dry laundry with the care symbol 'b', airtight fabrics (such as rubber-coated fabrics), delicate materials (silk, curtains made from synthetic fabrics) as they may crease, dripping-wet laundry due to high energy consumption, or wool or fabrics containing wool. Only dry laundry labelled as suitable for tumble-drying.
