  If you're experiencing minimal or no flow rate in your BWT Heating System, there might be a few reasons: * The AQA therm HFB-1717 BA may not be mounted in the direction of the flow rate. Ensure it is correctly mounted, following the arrow direction on the housing. * The shut-off ball valve might not be fully open. Make sure to fully open it. * The pressure reducer could be set at the wrong outlet pressure. Adjust it to the required setting. * The integrated filter could be dirty. Try cleaning the filter.

  Rhonda StaffordAug 15, 2025
  If the water isn't hard enough in your BWT Heating System, it could be due to several reasons: 1. The hardness range might be set incorrectly. Ensure you set the correct hardness range. 2. The AQA therm hardness-reducing cartridge (HRC) or desalination cartridge (SRC) might be depleted. If so, replace the cartridge with a new one. 3. Impurities might have entered the mixing inlets. Try flushing the (HRC, SRC) cartridge.
