Abstract

The aim of the invention is to provide a method for adapting a rinsing program in a dishwasher machine, said 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 there is insufficient salt, if the softening device is switched off, and if the dishwasher machine is on.

Claims

1-12. -12. (canceled)

13. A method for operating the rinsing program in a dishwasher machine, comprising:

adjusting the rinsing program in response to a selected one of a detection that no rinse aid has been added and the dishwasher machine is operating and a detection that, collectively, there is an absence of salt above a predetermined minimum quantity, the softening device is switched off, and the dishwasher machine is operating.

14. The method according to claim 13, wherein adjusting the rinsing program in response to a detection that no rinse aid has been added and the dishwasher machine is operating includes at least one of reducing, during the rinsing program, the number of changes of the solution in a partial program step intermediate rinse, reducing the number of changes of solution in a partial program step rinse, reducing the duration of a partial program step dry, and increasing the temperature associated with the partial program step dry.

15. The method according to claim 13, wherein adjusting the rinsing program in response to a detection that no rinse aid has been added and the dishwasher machine is operating includes commencing the operation of the softening device to soften the water and, optionally, commencing the operation of a lack-of-salt display despite it being switched off.

16. The method according to claim 13, wherein the step of adjusting the rinsing program includes detecting the absence of at least one of a rinse aid and a salt in an associated supply container above a predetermined minimum quantity.

17. The method according to claim 16, wherein the step of adjusting the rinsing program includes detecting via a sensor the absence of at least one of a rinse aid and a salt in an associated supply container above a predetermined minimum quantity.

18. The method according to claim 17, wherein the step of adjusting the rinsing program includes detecting via a selected one of a pH sensor and a water hardness sensor the absence of at least one of a rinse aid and a salt in an associated supply container above a predetermined minimum quantity.

19. The method according to claim 18, wherein adjusting the rinsing program in response to a 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 value, during the rinsing program, the number of changes of the solution in a partial program step intermediate rinse, adapting as a function of a detected value the number of changes of solution in a partial program step rinse, adapting as a function of a detected value the duration of a partial program step dry, and adapting as a function of a detected value the temperature associated with the partial program step dry.

20. The method according to claim 18, wherein adjusting the rinsing program in response to a detection that no rinse aid has been added and the dishwasher machine is operating includes commencing the operation of the softening device to soften the water to a minimum value in accordance with the detected value or degree of water hardness and, optionally, commencing the operation of a lack-of-salt display despite it being switched off.

21. The method according to claim 20, wherein commencing the operation of the softening device to soften the water to a minimum value includes commencing the operation of the softening device to soften the water to a minimum hardness of about 25°

dH.

22. A dishwasher machine, comprising:

means for executing a rinsing program which rinsing program can be adjusted if it is detected that no rinse aid has been added and the dishwasher machine is operating or if it is detected that there is a lack of salt as well as the softening device being switched off and the dishwasher machine is operating.

23. The dishwasher machine according to claim 22, and further comprising a sensor for measuring the properties of the corresponding cleaning liquid.

24. The dishwasher machine according to claim 23, wherein the sensor to measure the properties of the corresponding cleaning liquid is a pH sensor or a water hardness sensor.
