Abstract

The present invention relates to a washer/dryer (1) wherein the amount of laundry contained therein is detected. In the said washer/dryer (1), the weight of the load (L) in the drum (4) is determined by comparing the natural frequency of the drum (4) with the values previously recorded in the control unit (6) by the producer.
