Abstract

The present invention relates to a method and a device for cleaning of washing/dishing material in a number of steps in a washing machine/dishwasher, into which the material is placed in a cleaning space that may be closed. Water is supplied in one or more cycles to the cleaning space with or without chemical detergents, the material is cleaned during a certain time and at a certain temperature during one or more cycles in a cleaning process. The water with cleaning remains is discharged in one or more cycles form the cleaning space where supply of water, the cleaning process and discharge of water is controlled in dependence of, for instance, detection of the presence of cleaning remains and detergent in the water. The water is detected electrochemically by sensor instruments (1) using voltammetry by means of application of a varying electric potential over at least two electrodes (3, 4), which are in contact with the water in order to form an electric circuit (7). The present electric current's magnitude in the electric circuit is measured. The current's magnitude as a response to supplied potential using multivariate data analysis (MVDA) is analysed to acquire information in dependence of the contents of the water. Then a comparison with reference data is carried out for determining the contents of the water during the cleaning process and by means of control instruments (30) the cleaning process based on the determined contents of the water with respect to predetermined parameters, at least processing time and processing temperature.
