Abstract

A method of operating a dispensing system for a washing machine including a suds container for receiving wash liquid and at least one supply container for receiving a treating agent. The method includes selecting and activating a wash or treatment cycle from a plurality of wash or treatment cycles using an input device. The treating agent for delivery to the suds container is selected based on suitability information corresponding to the selected wash or treatment cycle. The treating agent is delivered to the suds container at the start of the activated wash or treatment cycle. The activated wash or treatment cycle is performed using a controller.

Claims

1. A method for operating a dispensing system for a washing machine including a suds container for receiving wash liquid and at least one supply container for receiving a treating agent, the method comprising:

receiving a first treating agent in a first container of the at least one supply container;

receiving a second treating agent in a second container of the at least one supply container;

selecting and activating a wash or treatment cycle from a plurality of wash or treatment cycles using an input device;

evaluating suitability information of the first and second treating agents based on the selected wash or treatment cycle, the suitability information quantifying the suitability of the treating agents for the specific selected wash or treatment cycle, the suitability information including a respective suitability information value for the first treating agent corresponding to each of the plurality of wash or treatment cycles and a respective suitability information value for the second treating agent corresponding to each of the plurality of wash or treatment cycles;

comparing the respective suitability information value for the first treating agent corresponding to the selected wash or treatment cycle with the respective suitability information value for the second treating agent corresponding to the selected wash or treatment cycle;

selecting one of the first and second supply containers based on the comparison if the corresponding suitability information value reaches a threshold value and delivering the respective treating agent from the selected supply container to the suds container at a start of the activated wash or treatment cycle; and

performing the activated wash or treatment cycle using a controller.

2. The method for operating a dispensing system as recited in claim 1, wherein the first treating agent and the second treating agent each include at least one of a detergent or a washing additive.
