Abstract

A washing machine has a rotatable drum and drum drive and a drum container for it, an inlet device to introduce water into the drum onto laundry therein, a pump and water pipes, several temperature sensors on the drum container, a heater for heating water and a washing machine controller connected to everything. Laundry in the drum is moistened with a defined quantity of water, wherein the moisture penetration varies depending on the fiber type of the laundry. Then a predefined quantity of water with a predefined temperature is applied to this laundry. The washing machine controller can deduce the fiber type of the laundry from the way how quickly and to what extent heat is extracted from this quantity of water.
