A method of cleaning soiled ware in a dishwasher, the method having the step of delivering a phosphate-free cleaning composition using a multi-dosing system, the composition comprising bleach, metal bleach catalyst and a complexing agent and wherein the complexing agent is slowly released as compared to the bleach catalyst.

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 dishwashing composition including a copolymer including polyalkylene oxide groups and quaternary nitrogen atoms and a complexing agent system comprising citrate.

The present invention relates to a pan cleaner system. The pan cleaner system comprises a main frame adapted to house a supply system, an inverting system and a cleaning system. The supply system, the inverting system and the cleaning system are configured to form a synchronized continuous functional line beginning by the supply system receiving a pan to be cleaned and ending by the cleaning system releasing a clean pan. The supply system comprises a first conveyor adapted to guide the pans towards the inverting and the cleaning systems. In one embodiment, the inverting system comprises a second conveyor adapted to magnetically hold the pans during the transport and the cleaning process. The pan cleaner system further comprises a releasing system adapted to release the pans from the magnetic conveyor once the cleaning process has been completed.

A method of washing ware in a dishwasher includes the steps of starting a dishwashing program; automatically locking the door and keeping it locked for the whole duration of the dishwashing program; and dosing at least 100 mg of active enzyme into the washing chamber. The dishwasher includes a washing chamber and a door to close the washing chamber.

A method for washing laboratory consumables comprises directing one or more liquid solutions to contact a plurality of laboratory consumables held by a rack, draining the one or more liquid solutions via a waste drain disposed proximate to a washing chamber configured to receive the one or more directed liquid solutions following the contact by the one or more liquid solutions with the plurality of laboratory consumables, and exposing the plurality of laboratory consumables to light in an ultraviolet (UV) range. The directing comprises introducing the one or more liquid solutions into a fluid input and out of a plurality of fluid outputs of a manifold dispenser. The number of fluid outputs is equal to the number of laboratory consumables such that each one of the fluid outputs directs the one or more liquid solutions at a corresponding one of the laboratory consumables.

A dishwashing composition including a copolymer which includes polyalkylene oxide groups and quaternary nitrogen atoms.

A condition warning system for an apparatus such as a pot and pan washing machine, a control system and control methods for a pot and pan washing machine are provided. The condition warning system includes a control system that monitors operational, safety or compliance parameters of an apparatus, and a light that illuminates a location below (or above) an operator's direct line of sight, and which is outside of the operator's direct line of sight. The control system and control methods include a punitive wash action lockout, an extended wash cycle time, and a deep clean wash cycle.

Disclosed a dishwasher, wherein dishes placed on a conveyor are washed, rinsed, and dried while being sequentially conveyed to a washing chamber, a rinsing chamber, and a drying chamber, the dishwasher including: a heat exchanger allowing hot air to be supplied to the drying chamber by heat exchange; a wash water tank in which water supplied to the washing chamber or the rinsing chamber is stored; and a spray device spraying water supplied from the wash water tank onto the dishes placed on the conveyor, whereby it is possible to save energy by providing a single heat exchanger to preheat wash water and rinse water and supply hot air to the drying chamber, and to improve circulation of wash water by a filtering device applied to a structure for reusing wash water, thereby improving sanitation of dishwashing.

A method of controlling a dishwasher is disclosed. The method includes supplying water to a sump, driving a wash pump using a wash motor, introducing a detergent into a tub, and determining whether the amount of bubbles is excessive based on the value of current applied to the wash motor. The determining whether the amount of bubbles is excessive is performed after a lapse of a predetermined period of time since the start of the introducing the detergent into the tub.
