Dishwashers and methods of control for operation of dishwashers are disclosed. The dishwasher may include an upper rack in an upper portion of a washing compartment for placing dishes, such as wine glasses, which are susceptible to damage. The dishwasher may also include an upper spraying arm in the upper portion of the washing compartment. During a wash cycle, the upper spraying arm can spray washing water toward the upper rack and steam may be supplied to the washing compartment at various intervals to reduce the risk of damage to the dishes and improve foreign matter removal. During a rinse cycle, water which may be heated in multiple stages by a sump heater may be sprayed toward the upper rack.

Controlling method of dishwasher

A method for controlling a dishwasher including the steps of first determining a steam operation mode for washing dishes and second determining at least one of a motor rotation speed, a number of repetitions of a steam supply step, a steam washing pattern, and an amount of detergent based on the determined steam operation mode.

A method for controlling a dishwasher includes sequentially performing a first main washing step, a second main washing step, and a third main washing step. The first main washing step includes supplying washing water, which is heated by a sump heater, to a washing chamber. The second main washing step includes selectively performing a steam spraying action for supplying steam to the washing chamber, and performing a water supplying action for supplying washing water to the washing chamber. The third main washing step includes supplying washing water, heated by the sump heater, to the washing chamber.

There is provided a method of controlling a dishwasher. The method includes performing a preliminary washing cycle, performing a main washing cycle, and performing a rinsing cycle. Steam is supplied during at least one of the main washing cycle and the rinsing cycle.

Method of controlling dishwasher

A dish washing machine and a control method of the same are disclosed. The control method of a dish washing machine includes supplying water into a washing compartment through spray arms, a first supplying steam, generated by a first steam generator, into the washing compartment, and when the abnormal operation of the steam generator is detected, terminating the operation of the first stem generator.

Method for controlling a dish washing machine

Dishwashers and methods of control for operation of dishwashers are disclosed. The operation of the dishwasher can include a drying cycle which uses a steam generator to supply steam to heat a washing compartment. The steam can evaporate moisture on the dishes in the washing compartment. When a condition of the dishwasher is met, such as a temperature or operation time meeting a preset value, an exhaust fan may exhaust air from inside the washing compartment. The operation of the dishwasher can improve power consumption and dry dishes more efficiently.

The present invention relates to a dish washing machine, and more particularly to a dish washing machine having a structure in which a bottom surface of the dish washing machine is not wet with water. The dish washing machine includes a washing chamber () for washing dishes, a fan () for discharging air from the washing chamber (), a housing for a space to install the fan (), an exhaust duct () for guiding the air from the housing () to an outside of the dish washing machine, and a passage for draining water to an outside of the housing () whenever the water is present in the housing ().

Dish washing machine

A dishwasher and controlling method thereof are disclosed, by which noise generated from rotation of a passage switching valve can be reduced in a manner of adjusting a rotation timing point of the passage switching valve and a rotation speed of a wash pump. The embodiments describe rotating a passage switching valve for switching a passage to selectively supply water to either an upper nozzle or a lower nozzle and reducing a rotational speed of a wash pump supplying the water to the upper and lower nozzles before the rotation of the passage switching valve.

Dishwasher and controlling method thereof

A method of controlling a dish washing machine capable of automatically washing items to be washed is disclosed. The method includes performing a steam spraying action defined to spray stream on a plurality of racks containing items to be washed, initiating a first water spraying action defined to spray on at least one first rack which is exposed firstly to the stream, and initiating a second water spraying action defined to spray water on at least one second rack, different from the first rack, wherein spraying water on the first rack begins prior to spraying water on the second rack.

Method of controlling a dishwashing machine having a steam generator

A method for controlling a dish washing machine is disclosed. The disclosed method includes turning off a heater of a steam generator when a water level sensor for the steam generator indicates a minimum water level, supplying water to the steam generator for a first time, to remove air bubbles around the water level sensor, and counting the number of repetition times of the water supplying step when the water level sensor still indicates the minimum water level after the execution of the water supplying step, and again executing the water supplying step, based on the counted value.
