Abstract
A method for operating a laundry machine having a rotatable drum a tub enclosing said drum; a water supply; a control unit a laundry treatment agent dispensing device configured to hold and deliver at least one of a laundry detergent and a laundry softener; and a control system configured to provide a softener signal that alternately assumes a first value indicating that no laundry softener will be delivered, and a second value indicating that laundry softener will be delivered. The method comprises: performing a washing phase in which detergent is delivered into the tub; and performing a number of rinsing phases wherein detergent from the washing phase is removed using water from said water supply apparatus, wherein the control unit sets the number of rinsing phases according to whether the softener signal assumes the first value or the second value.
