A method of controlling a dishwasher including a tub, at least one spray nozzle, a rack, and a microphone, includes: spraying, by the at least one spray nozzle, washing water while the at least one spray nozzle is rotating, analyzing a characteristic of a sound wave input to the microphone, the sound wave being generated based on the washing water colliding with one or more washing targets in the tub, determining whether a washing target made of a set material is present among the one or more washing targets based on the analyzed characteristic, determining, based on determining that the washing target made of the set material is present, a location in which the washing target made of the set material is present according to the analyzed characteristic, and reducing an amount of impact applied to the washing target made of the set material by the washing water.

Control method of dishwasher

The present disclosure relates to a dishwasher and a method of controlling the same. The dishwasher may determine an amount of foam in a wash space using a turbidity sensor measuring a turbidity value of wash water. Additionally, the dishwasher may perform a foam removal operation based on the amount of the foam in the wash space. In this case, the turbidity value measured by the turbidity sensor may be used. The foam removal operation may include a drainage operation, a water supply operation, and a wash operation that are consecutively performed, and may be performed in one or more of a pre-wash course, a main wash course, and a heating and rinsing course.
