Laundry washing machine with water softening system and method for controlling a laundry washing machine

A method for washing laundry in a washing machine utilizes a washing tub external to a rotatable washing drum. The method includes providing a quantity of detergent, providing a first quantity of water to form with the detergent a quantity of washing solution, introducing the washing solution into the tub, recirculating the washing solution inside the tub by recirculation until the washing solution is absorbed by the loaded laundry inside the drum and the level of the washing solution is below the drum, activating a heater for heating the wetted loaded laundry inside the drum deactivating the heater and maintaining the heated wetted loaded laundry inside the drum for a predetermined dry maintenance time, supplying a second quantity of water in the tub, rotating the drum, and rinsing the loaded laundry by drum rotations and by liquid drainage from the tub.
