An information processing method includes: selecting M blocks as M selected blocks from among N blocks for driving at least one of an actuator or a heater included in an apparatus, in accordance with an input operation performed by an operator; generating an application by setting, in accordance with an input operation performed by the operator, a parameter for driving the actuator or the heater in each of the M selected blocks; consulting a rule defining a parameter range within which the above-described driving is not permitted, and modifying the application by changing at least one of the M selected blocks, the at least one of the M selected blocks including a parameter included in the parameter range; and outputting the modified application.

A prewashing system includes a dish recognizing unit that recognizes a dish that is an object of prewashing executed prior to main washing, a first prewashing unit that performs prewashing of the dish that is the object of prewashing by a flow of water, a second prewashing unit that performs prewashing of the dish that is the object of prewashing by a washing tool, a prewashing method deciding unit that decides a prewashing method using at least one of the first prewashing unit and the second prewashing unit, on the basis of a form of the dish that is the object of prewashing, which is recognized by the dish recognizing unit, and a prewashing executing unit that executes prewashing of the dish that is the object of prewashing, by the prewashing method decided by the prewashing method deciding unit.

A dishwasher comprising: a first body; and a second body which includes a rack to hold an object to be washed, a spray nozzle to spray water onto the object, and a washing channel connectable to the spray nozzle, where the second body is coupleable to or coupleable from a top surface of the first body. The first body includes a washing pump to supply water, a supply channel to supply the water to the washing channel, a drain port to receive the water from the second body, and an upper housing which is coupleable to an opening formed at an upper surface of an external support such that so that while the upper housing is coupled to the opening the first body is positioned at a lower end of the upper surface of the external support.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A system and method for cleaning a reusable dish, comprising: picking a dirty dish from a load module disposed to contain at least one dirty dish with a robotic arm, wherein said dirty dish is stained with material that needs to be removed prior to reuse; transporting said dirty dish from said load module to a wash module with said robotic arm; cleaning said dirty dish in said wash module having the means to transform said dirty dish into a clean dish, wherein said clean dish does not exhibit any material that needs to be removed prior to reuse; transporting said clean dish from said wash module to a store module with said robotic arm; and dropping off said clean dish in said store module, wherein said store module is disposed to contain at least one clean dish, whereby each dirty dish is cleaned thoroughly and efficiently with individual attention in real time.
