A laundry treatment appliance having: a drawer comprising first and second compartments each being adapted to contain multiple doses of a treatment agent for laundry treatment, first and second pumps adapted to draw up treatment agent doses from the first and second compartments, respectively, and a control unit for controlling the first and second pumps, wherein the control unit is configured to cause the first and second pumps to coordinately draw up the treatment agent doses over at least one washing cycle by determining a gradual concurrent emptying of the first and second compartments over said at least one washing cycle.

Laundry treatment appliance with coordinated drawing up of treatment agent

A laundry appliance having a treatment chamber and a control unit configured to perform a first set of phases of a selected treatment cycle using a dose of a treatment agent, and a treatment agent delivering device. The control unit is further configured to: receive a first command that enables the delivering device and thereupon: calculate a first amount of treatment agent, and cause the delivering device to deliver the dose to the laundry treatment chamber; and, upon receiving a second command for an intensive treatment mode: cause the laundry appliance to perform a second set of phases in addition to said first set of phases, and calculate a second amount of treatment agent when both the first and second commands are received, so that said dose comprises said first amount of treatment agent plus said second amount of treatment agent.

Laundry appliance with improved intensive treatment mode

A laundry treatment appliance having a rotatable drum, an electric motor; at least one compartment to contain multiple doses of treatment agent, and a control unit The control unit is configured to, before delivering water: rotate the drum with a predefined speed profile comprising an accelerating ramp speed profile portion and a constant speed profile portion; estimate the amount of laundry load according to one or more parameters of the electric motor acquired during the drum rotation with the predefined speed profile; and according to said estimate, determine a treatment agent dose to be used during the selected laundry treatment cycle. The control unit is configured to, after determining the treatment agent dose, deliver water to the laundry load, and deliver the determined treatment agent dose to the laundry load.

Laundry treatment appliance with dry estimate of the amount of laundry load

A method to control a washing machine including a tub and a drum rotatably mounted inside the tub. The method includes and configured to contain laundry to be washed, the method comprising setting a wash cycle, calculating a first duration of the washing cycle based on a weight of the laundry before adding water to the tub, and: (i) when the weight is above the threshold, introducing water into the tub, calculating a second weight of the laundry, calculating a second duration based on the second weight, or (ii) when the weight is below the threshold, updating the first duration while executing the washing cycle, without calculating a second duration.

Method to control a washing machine and a washing machine

A method for operating a laundry treatment appliance having a casing within which a drum rotated by a motor is arranged, an opening provided in the casing for loading the laundry into the drum and a door adapted to open or to close the opening. The method includes performing a treatment cycle that includes: a) determining the amount of laundry load in the drum; and b) if the determined amount of laundry is outside a laundry load threshold range, issuing a warning to the user and waiting for a prescribed waiting time before starting the cycle, whereby during the waiting time the laundry treatment appliance switches to an operating mode in which the user to is allowed to change the amount of laundry load in the drum.

Method for operating a laundry treatment appliance and laundry treatment appliance

A method to control a laundry washing machine having&#x2014;an outer casing, a washing tub; a rotatable drum; a water softening device provided with ion exchanger agents designed to reduce the hardness degree of fresh water to be used during said washing program; a brine tank which is designed to supply, during a regeneration cycle, a prefixed amount of the brine to the water softening device for regenerating the ion exchanger agents; perform a waste-brine cleaning cycle for washing-out the waste brine solution contained in the water softening device and/or in the brine tank. The method controls the washing machine according to a washing program comprising one or more a washing phases, one or more rinse phases and one or more spin phases; and performs the regeneration cycle and the waste-brine cleaning cycle during respective washing program phases, which are different one to the other.
