      If the water from your BWT Water Dispenser is still hard, make sure to fill the brine cabinet with salt. Also, switch the power on and check the connections, or change the battery if it's battery operated. Ensure that the by-pass valve is closed and the inlet and outlet valves are open, or operate uniconnect. If needed, reset the hardness setting.

    What to do if the water level in my BWT Perla Silk L Water Dispenser's brine cabinet overflows?
    • K
      Keith WoodAug 30, 2025
      If the water level in the brine cabinet of your BWT Water Dispenser is overflowing, first check if the line pressure is within the specified range of 1.7 - 5.0 bar for UK by connecting a pressure gauge to a water outlet. If the pressure falls outside this range, install a pressure reducing valve or booster pump as needed. Also, inspect the drain line to ensure it is not kinked, blocked, or frozen. Finally, check that the power is on and connections are secure, especially after a power interruption.

    Why is my BWT Perla Silk L Water Dispenser constantly draining water?
    • K
      Kristy ParkerSep 1, 2025
      If water constantly runs from the drain of your BWT Water Dispenser, check if the unit is in recharge mode; if so, this is normal, and you should wait until the recharge is complete. Otherwise, ensure the power is on and all connections are secure, or replace the battery if it's battery operated.

      If the water level in your BWT Water Dispenser's brine cabinet is overflowing: * Check if the line pressure is within the water softener's specification by connecting a pressure gauge to a water outlet. Ensure the pressure is between 1.7 - 5.0 bar for UK. * If the pressure falls outside the specification, fit a pressure reducing valve or booster pump. * Inspect the drain line to ensure it is not kinked, blocked, or frozen. * Verify that the power is on and all connections are secure.
