An integral part of every dishwashing machine is an ion exchanger which traps the calcium and magnesium ions which cause hard water and feeds soft water into the machine. This is intended to prevent the development of limescale on glasses and cutlery. If the ion exchanger becomes saturated with calcium and magnesium ions, its absorptivity must be restored by means of regeneration. For this purpose, we use regenerating salt, which causes the exchange of the hardness ions and thus ensures optimal rinsing results. DOSAGE: As soon as the dishwasher’s ‘salt needed’ light turns on, fill the designated salt compartment with regenerating salt according to the machine manufacturer’s instructions for use. Experience shows that there are some machines which are very late in indicating their need for salt. To prevent this, the regenerating salt compartment should be regularly refilled even if the display does not yet indicate that it is required. If the salt compartment is completely empty, you should wait around 2 hours after refilling before switching the machine on again, to give the ion exchanger sufficient time to regenerate itself.
