Abstract

A water-conducting domestic appliance (1), especially a laundry treating device for washing laundry, comprises a treatment zone (16), a treatment agent container (10) serving to stock treatment agents, a metering device (7) having a plurality of metering pumps (8, 9) serving to meter the treatment agents for the treatment zone (16), and a control (5), the control (5) having a plurality of treatment programs. A user can select one of these treatment programs. The control (5) controls the metering device (7) depending on the selected treatment program. At least one treatment agent parameter, especially a treatment agent type or a treatment agent quantity, can be adjusted by the user. The control (5) carries out the selected treatment program depending on the treatment agent parameter.

Description

technical field [0001] The invention relates to a household appliance running with water, in particular to a laundry treatment appliance for washing laundry. In particular, the invention relates to the field of washing machines and combined washer-dryers. Background technique [0002] DE 29 49 254 A1 discloses a method and a device for monitoring and controlling the programs in an automatic washing machine, in particular the entry of water and the addition of detergent. In order to monitor and control the program, the number of rinse cycles and the dosing of added cleaning agent are controlled according to certain concentrations of cleaning additives dissolved in the rinse water. For example, the rinse cycle is terminated when the concentration of optical brightener in the rinse water has dropped to a minimum level. In this example, the sensor monitors the optical properties of the cleaning or rinsing water or its composition, wherein the control pulses for the required nu...
