Abstract (en)

The invention relates to a method for operating a washer dryer during a drying program, the washer dryer (2) comprising: a tub (52); a drum (58) arranged within the tub (52); an air channel (50) adapted to guide drying air, providing an air circulation arrangement; a drying air fan (48); a detergent dispenser (90) adapted to store at least one agent for a laundry treatment; a liquid connection line (94) connecting at least one outlet of the detergent dispenser (90) to the interior of the tub (52) or drum (58), wherein the fluid connection line comprises a siphon device (102), which, when filled with a liquid, provides a siphon function in the liquid passage of the liquid connection line (94); and a water supply arrangement (84) adapted to supply water to the detergent dispenser (90) and the liquid connection line (94). The method comprises: starting a drying program for drying the laundry; during the running drying program, monitoring at least one operation parameter; evaluating the at least one operation parameter; and if the evaluation of the at least one operation parameter indicates an incidence which may have affected the liquid level in the siphon device (102), supplying water to the siphon device by the water supply arrangement (84). Preferably one or more operation parameters are monitored for detecting an incidence. Further a washer dryer is provided having a control unit for implementing the control operation.
