Abstract (en)
[origin: DE19720820A1] The invention relates to a method for operating a household dishwasher, said dishwasher being equipped with a programme selection device and a combined device for adding a detergent and a clear rinse agent to the washing area. The aim of the invention is to improve the cleaning effect. To this end, the clear rinse agent is added not only once during the last wash cycle, but on several occasions at various times during the wash programme. Each of these processes is characterised by an adjustable number of equal quantities or a non-adjustable number of variable quantities of a clear rinse agent. A metering device for carrying out the inventive method comprises a reservoir (1), a temporary storage unit (3) and a metering chamber (6). Both the temporary storage unit (3) and the metering chamber (6) can be configured with an adjustable volume.
