Abstract

See full text

A method for operating a washer dryer comprising a tub, a drum mounted in the tub to be rotatable around an essentially horizontal axis for receiving laundry items, a process air circuit comprising an air heater and a blower to heat and circulate the heated air through the drum, a heat exchanger to condense moisture from the process air coming out of the drum, a sensor placed in the process air circuit between the tub and the heat exchanger, and a rinsing device, whereby the rinsing device flushes the sensor in a flushing phase with an aqueous cleaning liquid when the temperature T in the process air circuit between the tub and the heat exchanger is in a temperature range between an upper temperature limit Tmaxset and a lower temperature limit Tminset. The invention also relates to a washer dryer for performing this method.
