Description

technical field

[0001] The invention relates to a water-carrying household appliance comprising a water softening device according to the preamble of claim 1 . Background technique

[0002] Water-carrying domestic appliances are known, such as dishwashers including water softening devices. Water softening devices of the type described are used to reduce the hardness of water. This passes water through an ion exchanger containing ion exchange resins. In this configuration, water comes into contact with an ion exchange resin, wherein during passage through the exchanger, ions, especially calcium and magnesium dissolved in the water, are replaced by sodium ions of the ion exchange resin. Water of low hardness is then available at the outlet of the ion exchanger.

[0003] After a certain operating time after which the ion exchanger has been saturated with calcium and magnesium ions, the displacement capacity for sodium ions decays. The efficiency of the ion exchanger decreas...
