A dishwasher includes a dishwashing container, a lower holder for items to be washed arranged in the dishwashing container, and an upper holder for items to be washed which is arranged in the dishwasher container above the lower holder. A control device executes a dishwashing program from a number of dishwashing programs for washing the items to be washed by actuating a hydraulic facility in such a manner that in a first segment of the dishwashing program a washing liquor having a first washing liquor temperature is only sprayed by a lower spray facility onto the lower holder and in a second segment of the dishwashing program following the first segment washing liquor having a second washing liquor temperature that is lower than the first washing liquor temperature is sprayed by an upper spray facility onto the lower holder and the upper holder.

Provided are a method performed by an appliance for washing and rinsing goods, where some of the goods loaded into the appliance are sensitive to process water temperature changes, and an appliance performing the method. The method may include receiving via a user interface, an instruction that an appliance, during execution of a general-type washing program, should take into account that goods sensitive to temperature changes are loaded into the appliance, measuring a temperature value in a washing compartment of the appliance upon executing a draining process, and supplying fresh water to the washing compartment of the appliance. The method may include measuring, when the fresh water has been supplied, whether the process water being accommodated in a sump of the appliance is at a target temperature value or not and if not adjusting the temperature of the process water in the sump to attain the target temperature value.

A method for removing stains, in particular tea stains, during a cleaning cycle of a household appliance, such as a dishwashing machine. The cleaning cycle comprises at least a main wash cycle. A cleaning agent is released during the main wash cycle when the temperature inside the household appliance during the main wash cycle exceeds a predetermined temperature threshold, the threshold being higher than about 40° C., for example higher than about 55° C.

A method for operating a recirculating chemical-sanitizing dishwasher includes filling a wash tank of the dishwasher with water, and performing a first cycle of washing by circulating the water through a wash chamber of the dishwasher. A partial drain is performed of a first amount of water from the wash tank, and new water (for example, rinse water) is added to the wash tank for a second amount of water approximately equal to the first amount. A second cycle of washing is performed by circulating the water through the wash chamber of the dishwasher.

Surfactant systems and compositions incorporating the same are disclosed for use as rinse aids on plastics and other wares. The surfactant systems and compositions include both liquid and solid formulations, along with methods of use for treating plastics and other wares. The surfactant systems and compositions provide synergistic combinations allowing lower actives in composition formulations of the plastic-compatible surfactant systems providing good sheeting, wetting and drying properties.

An ultrasonic cleaning apparatus with a cleaning reservoir having a plurality of chambers, which are selectably fillable with cleaning fluid. The chambers of the multi-chamber reservoir are fluidly interconnectable, the apparatus further comprising a fluid distribution pump and a controller for sequentially controlling a fluid flow between the chambers during an ultrasonic cleaning cycle. Such a multi-chamber reservoir has the advantage of reducing the total volume of fluid required to clean vessels in the reservoir, since the cleaning process can be performed in a staged or sequential procedure, and the cleaning and/or rinsing fluid reused in each chamber, allowing the apparatus to be more compact.

The invention relates to a method of automatic dishwashing, comprising: placing soiled wares inside a cleaning volume; providing a first cleaning composition comprising a bleach and a second cleaning composition different from the first composition; and delivering the first composition and the second composition separately to the cleaning volume to contact the soiled wares, wherein: the first composition is delivered to the cleaning volume as a mist and the second composition is delivered to the cleaning volume as a jet; and the first and second compositions are delivered to the cleaning volume at a temperature below 100° C. The invention also relates to a dishwasher and a kit for use in the inventive method.

A method of cleaning a vessel including the steps of: a) providing a cleaning reservoir having a plurality of chambers each for holding a cleaning fluid; b) filling a first chamber of the cleaning reservoir with a cleaning fluid; c) ultrasonically cleaning one or more vessels in the first chamber using the cleaning fluid; d) transferring the cleaning fluid from the first chamber to a second chamber of the cleaning reservoir; and e) ultrasonically cleaning one or more vessels in the second chamber by reusing the cleaning fluid transferred from the first chamber and used to clean the one or more vessels in the first chamber.

The invention relates to a method of automatic dishwashing, comprising: placing soiled wares inside a cleaning volume; providing a first cleaning composition comprising a bleach and a second cleaning composition different from the first composition; and delivering the first composition and the second composition separately to the cleaning volume to contact the soiled wares, wherein: the first composition is delivered to the cleaning volume as a mist and the second composition is delivered to the cleaning volume as a jet; and the first and second compositions are delivered to the cleaning volume at a temperature below 100° C. The invention also relates to a dishwasher and a kit for use in the inventive method.

A dishwasher having a water pump, a water conduit connected to the water pump for distributing water in the dishwasher tub, a door for closing and opening the dishwasher, and a detergent dispenser located on the inside of the door. The detergent dispenser comprises a closeable cavity for receiving a detergent, an outlet into the tub, and a sealed dispenser water inlet configured to be detachably connected to the water conduit when the door is closed. Operation of the pump causes pressurized water to be directed directly to the inside of the detergent dispenser while the detergent dispenser is in a closed state.
