      First, check if the line pressure is within the water softener's specification by connecting a pressure gauge to a water outlet; it should be between 1.7 - 5.0 bar. If the pressure falls outside this range, fit a pressure reducing valve or booster pump as required. Also, ensure the drain line is not kinked, blocked, or frozen and check that the power is on and the connections are secure.
