  • the user is on the one hand pointed to the imminent damage caused by calcification of the device.
  • such a display can be used on a targeted use of descaling agents and thereby avoiding their unnecessary use.
  • a disadvantage of this solution is that the measured value detected by the turbidity sensor measures an impermissibly high degree of hardness, in which calcification has already taken place in the household appliance.
  • the user is not informed prior to the onset of calcification in the household appliance in order to take early countermeasures that do not lead to damage in the household appliance.
