1. A method for operating a water-bearing household appliance for treating articles, the water-bearing household appliance comprising:
a treatment chamber for treating the articles with a washing liquor; and
a dosing system for dispensing a dosing-amount of detergent provided by a dosing unit, the method comprising:
selecting one of a plurality of different treatment cycles,
controlling the water-bearing household appliance to perform the selected treatment cycle;
actuating the dosing system to dispense the dosing-amount of detergent according to the selected treatment cycle,
detecting a sensor signal generated by an impact of the dispensed dosing-amount of detergent after the dispensed dosing-amount of detergent is released from the dosing system, wherein the impact of the dispensed dosing-amount of detergent that generates the sensor signal is detected outside of the dosing unit, and wherein the sensor signal is a mechanical signal that is generated by an impact of the dosing-amount of detergent hitting a deflecting element after being dispensed and before being added to the washing liquor;
adjusting the selected treatment cycle as a function of the detected sensor signal; and
controlling the water-bearing household appliance to perform the adjusted treatment cycle.
