• the method comprising at least one washing phase during which said laundry is washed with introduction of water and said detergent into said washing tub and tumbled by rotation of said washing drum, at least one successive draining phase for draining liquid from said washing tub and following said draining phase at least one rinsing cycle during which said laundry is treated by means of said at least one rinse additive;
• wherein said rinsing cycle comprises the steps of:
• introducing a quantity of said rinse additive into said washing tub;
• introducing a first quantity of water into said washing tub by activating said supply valve;
• activating said first recirculation circuit for withdrawing liquid from said washing tub and re-admitting said liquid into said washing tub in such a way that a diluted rinse additive is obtained by mixing said quantity of said rinse additive with said first quantity of water at said bottom region of said washing tub;
• introducing said diluted rinse additive into said washing drum in order to be absorbed by said laundry.
