A method of treating laundry in a laundry treating appliance having an air supply system and a heating system both operably coupled to and controlled by a controller to supply heated air to a rotatable drum defining a treating chamber, the method including the application of an enzyme solution to the laundry during a cycle of operation.

Method for dispensing an enzyme in a laundry treating appliance

A dishwasher has a treating chamber for receiving dishes for treatment according to an automatic cycle of operation and a dispensing system for storing and dispensing treating chemistry to the treating chamber during the cycle of operation. The dishwasher can be provided with a lifetime supply of a treating chemistry for the dispensing system.

Dishwasher

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 treating laundry in a laundry treating appliance having a treating chamber for receiving the laundry for treatment according to an automatic cycle of operation implemented by a controller of the laundry treating appliance includes receiving by the controller an input indicative of the laundry comprising at least one new laundry item.

Methods and compositions for treating laundry items

Systems, components, and methodologies for uniformly distributing fabric enhancers onto laundry loads in laundry treating appliances. The methods may include accepting one or more of a laundry detergent, a fabric softener, and a bleach for dispensation into the laundry treating appliance, accepting a plurality of fabric enhancers in respective compartments of a fabric enhancer storage assembly, receiving indications of the types of fabric enhancers stored in the respective compartments, selecting dispensation patterns suitable for each of the types of fabric enhancers, and dispensing the plurality of fabric enhancers in accordance with the selected dispensation patterns.

Fabric enhancer and laundry additive dispensation in laundry appliances

A clothes dryer for drying fabric items in accordance with a treating cycle of operation, includes a treating chamber receiving fabric items for treatment and a controller having a memory in which is stored a set of executable instructions comprising at least one user-selectable cycle of operation, the controller may receive an indication of a dye transfer event and implement a cycle of operation based thereon.

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.

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 for treating laundry in a laundry treating appliance including the application of an enzyme solution to the laundry during a cycle of operation.

Disclosed is a method of operating a laundry treating appliance having a treating chamber that receives a laundry load for treatment according to a cycle of operation. The method includes determining the size of the laundry load in the treating chamber; supplying a predetermined amount of liquid to the treating chamber based on the determined load size; applying mechanical energy to the laundry treating chamber by driving a clothes mover with an electric motor; determining a difference between an in-rush current to the electric motor and a steady-state current of the electric motor during the applying of the mechanical energy; and determining a laundry load type of the laundry load based on the determined difference.

Method to determine fabric type in a laundry treating appliance using motor current signature during agitation

A cycle of operation for a laundry treating appliance having a rotatable treating chamber in which laundry is received for treatment according to an automatic cycle of operation, the cycle of operation including a pre-wetting phase which includes misting an exposed surface of the laundry with a pre-wetting liquid and a pre-wash phase which includes supplying a dye fixative to the surface of the laundry wet by the pre-wetting liquid for distributing a dye fixative to a laundry surface.

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.

A method for inhibiting dye transfer between items of laundry in a fabric treating appliance including a treating chamber for receiving the fabric items for treatment according to a cycle of operation, the method including supplying liquid to the treating chamber to form a liquid mixture comprising the liquid and free dye molecules and dye absorbers in solution or in suspension within the liquid mixture. At least one of ultraviolet (UV) or visible light spectroscopy may be conducted on the liquid to define at least one of an absorbance or fluorescence value indicative of a level of at least one of the dye absorber or complex in the liquid.

A method for treating laundry in a laundry treating appliance having an air supply system and a heating system both operably coupled to and controlled by a controller to supply heated air to a rotatable drum defining a treating chamber including the application of a lipase solution to the laundry during a cycle of operation.
