  If your BWT Water System's electronic display is showing an error code “Err 1” or “SALt” and an audible alarm is sounding, or if the digital display is blank, first ensure all connections are secure. Then, turn the power off for 10 seconds and turn it back on to allow the system to reset. If the low salt alarm is active, fill the brine cabinet with salt and press the [SET] key to reset the salt alarm to full capacity. Finally, verify that the power is on and all connections are secure.

  If your BWT Water System is still producing hard water, ensure there is a minimum of 150 mm of salt in the brine cabinet and that the power is on with secure connections. Verify that the softener is online by closing the bypass valve and opening the inlet and outlet valves. If needed, manually restart the regeneration process. Also, check and reset the hardness setting if it is incorrect.

What to do if BWT bestsoft 11 brine cabinet overflows?

  Austin BookerAug 17, 2025
  If the water level in your BWT Water System's brine cabinet reaches overflow, check that the line pressure is within the specified range: 1.7 - 5.0 bar for the UK / 1.0 - 8.0 bar for EU. Use a pressure gauge connected to a water outlet to verify. If the pressure is outside this range, fit a pressure reducing valve or booster pump as required. Also, inspect the drain line to ensure it is not kinked, blocked, or frozen. Finally, confirm that the power is on and the connections are secure.
