A method of treating dishware in a domestic automatic dishwashing machine for from 30 minutes to 50 minutes includes washing the dishware for from 15 minutes to 30 minutes and rinsing the dishware for from 15 minutes to 30 minutes. Washing the dishware includes dosing from 2.0 litres to 5.0 litres of water into a cleaning chamber of the domestic automatic dishwashing machine and contacting the dishware in the cleaning chamber with the wash water. At least 10 minutes of washing the dishware is carried out at a temperature ranging from 40° C. to less than 50° C. Rinsing the dishware includes dosing from 2.0 litres to 5.0 litres of rinse water into the cleaning chamber and contacting the dishware in the cleaning chamber with the rinse water. At least 7 minutes of rinsing the dishware is carried out at a temperature ranging from 55° C. to 65° C.

A dishwasher for treating dishes according to a cycle of operation, the dishwasher comprising a tub at least partially defining a treating chamber, a dish rack received within the treating chamber and configured for receiving dishes for treatment during the cycle of operation, a sprayer located within the treating chamber and above the dish rack, and emitting a liquid onto the dish rack to form a high-speed spray.

A household dishwasher includes a washing tub, a main body, a door portion configured to open and close an upper surface of the washing tub, a first washing water spray nozzle configured to spray washing water supplied from a door portion water supply pipe to an inside of the washing tub, a second washing water spray nozzle configured to spray the washing water to the inside of the washing tub, a steam generator configured to supply steam to the inside of the washing tub, an ultrasonic vibration part configured to apply ultrasonic vibration to the washing water inside the washing tub such that an ultrasonic washing is performed, and a controller configured to receive a washing command signal of a user and control internal components of the household dishwasher.

Methods of dishwashing to remove soils are disclosed, including a first detergent wash step, wherein the detergent is substantially-free of water conditioning agents including polycarboxylic acid polymers and phosphonates, followed by a second step of rinsing under high temperature with a water conditioning agent, namely polycarboxylic acid polymers. The methods result in little to no precipitation forming on the treated ware due to the treating of the hard water before it contacts the alkalinity source which prevents precipitation and/or flocculation from occurring.

A method of controlling a dishwasher includes washing an object accommodated inside a tub by spraying water and detergent onto the object, rinsing the object by spraying water onto the object, drying the object by removing moisture adhered to the object, detecting an amount of a rinsing agent, comparing the detected amount of the rinsing agent to a predetermined amount, based on the comparison, determining whether the detected amount of the rinsing agent is less than the predetermined amount, and increasing at least one of a temperature of water to be supplied in the rinsing or a drying time in the drying based on determining that the detected amount of the rinsing agent is less than the predetermined amount.

A dishwasher with a tub that defines a treatment chamber, a sump fluidly connected to the tub, sprayers within the treatment chamber, a drain pump fluidly connecting the sump to a discharge pipe, a water tank fluidly connected to the sump with a controllable valve, a softener, and a diverter valve fluidly connecting the sump and the sprayers.

A dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.

The invention relates to a method of automatic dishwashing of dishware using wash water, in which, in a first step, a first composition, which comprises an oxygen bleach but substantially no enzyme, is supplied to the wash water, and the dishware is washed in a washing zone with the oxygen bleach-containing wash water; and, in a second step which occurs after the first step, a second composition, which comprises an enzyme but substantially no bleach, is supplied to the wash water, and the dishware is washed in said washing zone with the enzyme-containing wash water. The invention also relates to an automatic dishwasher and a cartridge suitable for use in this method.

A method of cleaning ware in a domestic dishwasher using a program having a main wash and a rinse cycle, the method having the step of delivering a dose of a cleaning composition wherein the delivery of the cleaning composition is split between the main wash and the rinse.

A method for cleaning cutlery or cutlery parts, wherein the method includes the method step of filling a cutlery holder with the cutlery to be cleaned, the method step of treating the cutlery to be cleaned with a washing liquid, and the method step of treating the washed cutlery with a clear rinsing liquid. The cutlery holder is filled with the cutlery to be cleaned such that the individual cutlery parts are movable relative to each other and/or relative to the cutlery holder, wherein at least during clear rinsing and preferably also during washing, the cutlery parts are moved at least once and preferably several times relative to each other and/or relative to the cutlery holder in order to avoid static contact points between the individual cutlery parts and/or between the cutlery parts and the cutlery holder. A corresponding cutlery holder, and a dishwasher are also provided.
