  • Solution transferred to the ion exchanger chamber (7) is kept therein for a given period in order to weaken hardness elements accumulated on the ion exchanger chamber (7) and make them leave the ion exchanger chamber (7). Since the solution (regeneration liquid) contains oxidizing agents, it should not contact the machine parts. Therefore, the solution in the ion exchanger chamber (7) is removed out of the machine by the second discharge arrangement. The washing liquid contained in the washing compartment (9) is removed out of the machine by the first discharge arrangement and the second discharge arrangement.
