The use of the descaling cartridge extends the lifetime of the device by ten times (based on operation without a cartridge, a water hardness of 20 °dH (degrees German hardness) and a carbonate hardness of 15 °dH (degrees German hardness), based on internal durability tests). Regular replacement of the descaling cartridge at the maintenance interval is essential.
