  • the cleaning parameters of the cleaning program P that can be changed according to the type of detergent that has been detected are one or a combination of more than one of the following parameters:
  • the parameters of the cleaning program P that can be changed vary according to whether a liquid detergent D2/D3 or a tab detergent D1 has been recognized.
  • the program P operates the washing pump and the heating resistor for a first predetermined time interval, e.g. a few minutes, and then continues with the washing operation for a second time interval, that is longer than the first time interval.
  • the next rinsing step includes a washing and heating step whose duration is equal to a third time interval, shorter than the first time interval.
  • the program P operates the washing pump and the heating resistor for a first time interval and then continues with the washing operation only for a second time interval, that is shorter than the first time interval.
  • the next rinsing step includes a washing and heating step whose duration is equal to a third time interval, that is shorter than the first and second time intervals.
  • the comparison step 13 when comparing the at least a portion of the acquired contour Cpar, i.e. the at least one contour portion Cpar, with a predetermined contour Cpred, comprises a step of checking such said at least a portion of the acquired contour Cpar is analogous to the predetermined contour Cpred, to thereby determine the type of detergent TD1, such as a detergent tablet, i.e. a tab D1.
  • the term analogous is intended to designate the case in which the portion of the acquired contour Cpar is comparable or similar, within a predetermined percent deviation, with the tab contour that has been previously stored. For example, if the comparison results in deviation of 10% or less between the acquired portion of the contour Cpar and the stored contour Cpred, then the acquired portion of the contour Cpar will be identified as belonging to a previously stored contour. Otherwise, the acquired image 11A is repeatedly processed until the type of detergent is determined or identified as a detergent with average characteristics (i.e. with average chemico-physical properties).
  • the comparison step 13 in case of comparison between the acquired roughness value Racq with a threshold roughness value Rth, comprises the step of assessing whether such acquired roughness value Racq is:
  • the step of comparing the threshold value Rth with the acquired value Racq is carried out by assessing the deviation between the two imaginary lines, even when the door 7 has been opened.
  • the method can detect whether there is a detergent D1, D2 or D3 in the dispenser 6.
  • the method comprises a step 15 of providing a first capacity value Vin for the dispenser 6, said first value identifying the volume of the dispenser when it is empty.
  • the method comprises a step of processing 17 the first captured image 11a to generate a second processed image 12B that defines a second capacity value for the dispenser 6, i.e. the value identifying the volume of the dispenser 6 when there is a detergent D1, D2 or D3 therein.
  • the method includes a step of comparing (18) the first processed image 12A with the second processed image 12B to determine a residual capacity value Vres identifying the free volume of the dispenser 6.
  • this comparison step 18 results in a residual capacity value Vres that is greater than 60% based on the first capacity value Vin, then there is no detergent in the dispenser 6.
  • the result of the comparison step 18 may be combined with the processing step 12 to combine the information that can be obtained from the processed image 12A with the residual capacity value Vres to thereby obtain a higher degree of reliability in the identification of the type of detergent TD1, TD2, TD3.
  • the method comprises a step 23 of notifying the type of detergent TD1, TD2, TD3 and/or the changes made to one or more of the parameters of the cleaning program P, through the user interface 9, to promptly inform the user of the changes that have been made.
  • the method and the dishwashing machine 1 allow a change of the operating state of the machine to be notified through the user interface 9, allowing actions to be taken to restore the proper installation conditions of the object. This will reduce the need to wash part of the dishware and/or repeat the washing cycle, leading the water, detergent and power consumption.
