Abstract (en)

[origin: EP0008819A1] The dishwashing machine operation is improved by the provision of an additional ion-exchange device for removing bicarbonate ions comprising a column (1) containing an anion-exchange resin in the intake water line. The device can be installed as a separate device connected in series either before or after the existing water-softening device or in parallel or it can form an integral part of the water-softening device. The invention enables the use of lower alkaline detergent products.
