    What to do if BWT Rondomat Duo-I 3 displays low salt?
    • B
      Bryan HoffmanAug 16, 2025
      If your BWT Water Dispenser displays a low salt warning, it means the regenerative wasn't refilled in time. To resolve this, siphon off or extract the brine to the level of the sieve base before refilling the regenerative. Incorrect refilling can cause the softened water to become salty.

    What to do if my BWT Water Dispenser display indicates low salt (low salt! date time)?

      If your BWT Water Dispenser display indicates low salt (low salt! date time), it means the regenerative was not refilled in time. The brine must be siphoned off or extracted to the level of the sieve base. Only after this has been done can the regenerative be refilled. If this is done incorrectly, the softened water will be salty.

    Why is my BWT Water Dispenser not supplying enough water?

      Nancy CrawfordAug 28, 2025
      If your BWT Water Dispenser isn't providing sufficient water or the flow is weak, the inlet pressure might be too low, or the compressed air pressure could be insufficient. Try increasing the inlet pressure, adjusting the pressure reducer if needed, and start a manual regeneration. Also, check the inlet pressure and initiate regeneration.

      andrew20Aug 30, 2025
      If your BWT Water Dispenser isn't supplying softened or blended water, it could be due to a lack of regenerative in the salt/brine container or a power supply interruption. Refill the regenerative, wait approximately one hour, and then manually regenerate the system. Also, ensure the electrical connection is properly re-established.

      Alexandra BrownSep 10, 2025
      If your BWT Water Dispenser is not supplying softened or blended water, it might be due to no regenerative in the salt/brine container or a power supply cut off. Refill the regenerative, wait approximately 1 hour, and then regenerate manually. Also, re-establish the electrical connection.
