Abstract (en)
The invention relates to a process for operating a washer dryer comprising a tub 1, a drum 2 mounted in the tub 1 to be rotatable around an essentially horizontal axis 30 for receiving laundry items 5, a control unit 16, a process air circuit 4 comprising a liquefier 8 of a heat pump circuit 8,9,10,11 and a blower 6 to heat and circulate the heated air through the drum 2, an evaporator 9 to condense moisture from the process air coming out of the drum 2, a temperature sensor 19, 20, 21, and a rinsing device 12, wherein: (a) the temperature sensor 19, 20, 21 measures a temperature value T app in the process air circuit 4 or the heat pump circuit 8,9,10,11 which are indicative of a temperature of the refrigerant in the heat pump circuit 8,9,10,11; and (b) the rinsing device 12 flushes the evaporator 9 with an aqueous liquid 15 when the temperature T app reaches or exceeds an upper temperature limit T max set .
