  • Patent number: 10400377
    Abstract: A method for controlling a wash process in a washing appliance includes supplying a detergent in the washing appliance; detecting a type of detergent supplied; performing a wash cycle that ends with a washing liquor drain; and performing a rinsing cycle in accordance with the detected type of detergent. When the detected detergent is a powder detergent, water is introduced into the washing chamber for a first rinsing step. Between the washing liquor drain and the first rinsing step, laundry is tumbled in the washing chamber at at least one of a revolving speed lower than a minimum spinning speed so that no spinning is performed between said washing liquor drain and the first rinsing step, or for a time interval different from the corresponding time interval during which the laundry is tumbled in a rinsing cycle where a liquid or gel detergent is detected.
