Abstract

A dishwashing machine, and a method and system for automatically evaluating the degree of cleanliness of a filtering system are disclosed. In the method, the dishwashing machine includes a washing zone provided with a washing fluid collection zone in which a filter is positioned. The method includes acquiring a first digital image representative of a first condition of the filter; digitally processing the first digital image so as to obtain a first processed image identifying a first surface value; acquiring a second digital image representative of a second condition of the filter; digitally processing the second digital image so as to obtain a second processed image identifying a second surface value; comparing the second surface value with the first surface value to calculate an occlusion percentage value of the filter when passing between the first condition and the second condition; generating a dirt presence signal indicative of the presence of an accumulation of dirt in said filter, when the occlusion percentage value of the filter exceeds a predefined threshold value; generating a sound and / or visual signal indicative of an obstructed filter condition, when the dirt presencesignal is generated.
