Abstract

The invention discloses a dishwasher anomaly detection method. The method comprises the steps that in the process that a spraying arm of a dishwasher carries out rotary spraying, a control unit obtains the resonant frequency, collected by a detection unit, in a dishwasher cavity, compares the obtained resonant frequency with a preset value, and judges whether an abnormal condition exists in the dishwasher cavity or not, wherein the abnormal condition comprises foreign matters in the dishwasher cavity and / or wrong placement of tableware in the dishwasher cavity. According to the invention, whether foreign matters exist in the washing chamber or not and the abnormal condition of wrong placement of articles are detected so that a user can be reminded in time, the user can find reasons and solve problems in the shortest time, and the influence on user experience and a tableware cleaning effect is avoided.
