Abstract
The method detects impermissible operating states in a hot-air clothes dryer with a laundry drum. The temperature in the incoming air flow is detected periodically downstream of an incoming air heater and upstream of the drum. A differential value (difference value or gradient) is formed from two successively detected values. The differential value is compared with a predetermined differential value, and if the newly formed differential value is absolutely greater than the predetermined differential value, then a counting value is incremented by one step. The counting value is compared with a predetermined counting value and, if the current counting value is greater than the predetermined counting value, then the heating of the dryer is turned off and/or an operating state display is activated.
