Method for operating a dishwasher

摘要

Method to operate a dishwasher, comprising the following consecutive steps:
1. adding detergent to a cleaning liquid which is circulated within the dishwasher;
2. measuring the conductivity of the cleaning liquid and determining the rate of change in conductivity caused by dissolution of the detergent in the cleaning liquid;
3. comparing the rate of change in conductivity with a predetermined threshold value so as to determine the dissolution rate of the detergent that has been added in step 1 to the cleaning liquid; and
4. adjusting operating parameters based on the determination of step 3, wherein in step 3 it is determined whether a detergent in powder form or a detergent tablet has been added in step 1, further comprising predetermining an average detergent tablet dissolution duration required for dissolution of a detergent tablet in the cleaning liquid, and wherein in step 2 the rate of change in conductivity is determined by measuring the conductivity of the cleaning liquid at a time after addition of the detergent which is shorter than said average detergent tablet dissolution duration.
