- the dosage of the individual cleaning substances is carried out according to a predetermined amount.
- at least one program step is sensor-controlled. For example, adjustment of the dosage can take place by means of turbidity measurement or conductivity measurement.
- a "pre-rinse" program step in which an alkali carrier and a dispersant are added, and the dosing can be carried out simultaneously or at different times.
- an enzyme and / or a surfactant are additionally added in the program step "prewash.”
- the enzyme may be protease, amylase or lipase, while the surfactant may be, in particular, a nonionic In this case too, the dosage can take place simultaneously or at different times.
- a program step "cleaning" in which an alkali carrier, a dispersing and / or complexing agent and at least two enzymes are added at a time interval
- Components can again be separated from one another at the same time or in time, in the case of the alkali carrier and dispersant and / or complexing agent.
- the two enzymes such as protease and amylase, however, must be added separately in time, since the protease affects the effect of amylase negative.
- a fat-splitting enzyme and / or a surfactant are added.
- lipase is added as fat-splitting enzyme and a nonionic surfactant as surfactant for improving the dispersion.
- the addition of the surfactant can be carried out simultaneously with another component or separated in time.
- a program step "intermediate rinsing" is provided in which alkali carriers and a dispersing agent are added, the dosing can take place simultaneously or separately, the addition of alkali carriers in the intermediate rinsing step allows preparation for removal of Tea dirt by means of a bleach, since for optimal removal of Teeschmutz a certain pH value must be achieved.
- a program step "rinsing” in which a dispersing and / or complexing agent, a bleaching agent, a bleach activator and a surfactant are added thereto Water hardness reduced and metal ions also complexed, which facilitates, for example, the removal of, for example, Teeschmutz.
- a bleaching agent such as hydrogen peroxide Bleaching agents are added separately from enzymes, preferably in the last program step
- the bleaching agent can be added together with any other component at the same time.
- the bleach activator thereby supports the bleaching action of hydrogen peroxide at temperatures below 80 ° C., so that an optimum bleaching effect is achieved by
- Bleach activator can be carried out together with the dosage of the bleaching agent or offset in time.
- a surfactant such as a nonionic surfactant causes a rinse effect by lowering the surface tension of the
- the dosage of this component may be simultaneous with another

Time-shifted, for example, about 5 min later, the enzyme protease is added in step 3 in order to decompose proteins and / or peptides (protein compounds).
- sodium hydroxide solution is the last added in a step 4 at a temperature of about 50 9 C as an alkali carrier, so that the pH of the wash liquor increases, which improves the effect of enzymes during the subsequent Nachwaschphase.
- the final step is a rinse, in which the rinse liquor is heated to about 85 9 C.
- a dispersing and / or complexing agent is added in order to complex ions, in particular alkaline earth ions, and at the same time to facilitate the detachment of dirt, for example tea stains, by this complexation of metal ions.
