A method of operating a laundry treating appliance with a combination washer/dryer having a cabinet defining an interior, a tub located within the interior, and a rotatable drum located within the tub interior and defining a treating chamber, and an air recirculation conduit, the method comprising supplying water to the treating chamber, rotating the drum, and draining the water from the laundry treating appliance.

Laundry treating appliance for drying laundry

A method of operating a laundry treating appliance having a tub, a rotatable drum at least partially defining a treating chamber, and a treating chemistry dispenser comprising multiple treating chemistry cups configured to dispense treating chemistry to the treating chamber. The method comprises performing a first wash cycle and dispensing a first dose of treating chemistry from one of the treating chemistry cups, receiving at a controller a user selection of an activation of a performance enhancement selector, and upon activation of the performance enhancement selector, activating a second wash cycle comprising dispensing a second dose of treating chemistry from another of treating chemistry cups.

Fabric cleaning appliance with performance enhancement selector

The laundry treating device has a user interface configured to receive a user selection of a preprogrammed wash cycle. A treating chemistry dispenser has multiple treating chemistry cups configured to dispense treating chemistry to the treating chamber during the selected washing cycle. A controller configured to activate dispensing from each of the treating chemistry cups at preprogrammed times during the wash cycle. A performance enhancement selector configured to receive a user selection such that activation of the performance enhancement selector causes the controller to dispense one of the treating chemistry cups at a different time than the preprogrammed time during the wash cycle.

Lifter for a laundry treating appliance

A laundry treating appliance having a tub with a tub interior that defines a liquid chamber, a rotatable drum located within the liquid chamber and rotatable about a rotational axis that at least partially defines a treating chamber, and a lifter housing carried by the drum and located within the treating chamber.

Laundry treating appliance lifter

A method of automatically initiating a procedure to adjust dosing of laundry treating chemistry after satisfying a threshold of determined over-sudsing conditions in a laundry treating appliance during a cycle of operation. The number of over-sudsing condition is aggregate. Once the aggregate total satisfies a predetermined threshold, a predetermined dosage of laundry treating chemistry is adjusted. The over-sudsing aggregate total can also be reset in the event of an operational event such as a replenishment of a bulk treating chemistry, input by a user of a default value, or passing of a temporal reference, wherein the predetermined dosage is reset to a default value.

Laundry treating appliance with over-sudsing condition compensation measures

A method and apparatus for operating a laundry treating appliance comprising a treating chamber for receiving a load of laundry for treatment according to at least one cycle of operation wherein a dye containing liquid is generated in the treating chamber during the operation, the method comprising backwashing the pre-filter to remove the non-dye material from the pre-filter.

Laundry treating appliance with pre-filter backwashing

A method of automatically initiating a procedure to adjust dosing of laundry treating chemistry after satisfying a threshold of determined over-sudsing conditions in a laundry treating appliance during a cycle of operation. When an over-sudsing condition is detected, an over-sudsing counter is initialized, and the data is stored in the memory of a laundry treating appliance as an aggregate total. Once a predetermined threshold is satisfied, a predetermined dosage of laundry treating chemistry is reduced and the over-sudsing counter is reset. The over-sudsing counter can also be reset in the event of an operational event such as a replenishment of a bulk treating chemistry, input by a user of a default value, or passing of a temporal reference, wherein the predetermined dosage is reset to a default value.

A method of operating a laundry treating appliance having a rotating drum at least partially defining a treating chamber for the receipt of laundry for treatment according to an automatic cycle of operation includes a dye fixative removal phase that includes supplying heated water in the treating chamber and adjusting the pH of the heated water.

Methods and compositions for treating laundry items

A reduced dye transfer cycle of operation for a laundry treating appliance having a treating for receiving laundry for treatment includes a treating chemistry application phase where a treating chemistry is supplied to the treating chamber, the treating chemistry including at least one water soluble cationic dye absorber, a surfactant system, and an emulsifier.

A method of operation for a laundry treating appliance having a treating chamber for receiving laundry for treatment includes a pre-wetting phase, a wash phase, and a rinse phase and further includes a dye fixative phase, a first dye absorber phase, and a second dye absorber phase.
