Abstract

A method for adapting a rinsing program in a dishwasher machine, and a dishwashing machine configured to perform the method, the method enabling the rinsing program run of a dishwasher machine to be adapted in such a way that satisfactory cleaning and drying performances are achieved even when using a combination rinse aid. To this end, the rinsing program run is adapted if a clear rinsing agent is not added, and if the dishwasher machine is on.

Claims (10)

1. A method for adapting a rinsing program in a dishwasher machine, comprising:

adapting the rinsing program including selectively varying one of a rinse water content, a temperature of the rinse water, and a duration of application of the rinse water in response to a detection that no rinse aid has been added and the dishwasher machine is operating.

2. The method of claim 1 , wherein the adapting includes one of reducing, during the rinsing program, the number of changes of the solution in a partial program step intermediate rinse, and reducing the number of changes of solution in a partial program step rinse.

3. The method according to claim 1 , wherein the adapting the rinsing program includes detecting the absence of a rinse aid in an associated supply container above a predetermined minimum quantity.

4. The method according to claim 1 , wherein the adapting the rinsing program includes detecting the absence of a rinse aid in an associated supply container above a predetermined minimum quantity via a sensor for measuring the chemical properties of the rinsing solution.

5. The method according to claim 4 , wherein the adapting the rinsing program includes detecting via a pH sensor the absence of a rinse aid in an associated supply container above a predetermined minimum quantity.

6. The method according to claim 5 , wherein the adapting the rinsing program in response to the detection that no rinse aid has been added and the dishwasher machine is operating includes at least one of adapting as a function of a detected pH value, during the rinsing program, the number of changes of the solution in a partial program step intermediate rinse, and adapting as a function of a detected pH value the number of changes of solution in a partial program step rinse.

7. A dishwasher machine, comprising:

a controller that adapts a rinsing program by selectively varying one of a rinse water content, a temperature of the rinse water, and a duration of application of the rinse water if it is detected that no rinse aid has been added and the dishwasher machine is operating.

8. The dishwasher machine according to claim 7 , and further comprising a pH sensor for measuring the properties of the rinsing solution.
