  If your Viessmann Water Dispenser supplies water that is too hard, it might be due to a few reasons. First, check if there is enough salt in the tank and refill it if needed. You may also need to activate manual regeneration. Another possible cause is a power outage, so restore the power supply, check the displayed time, and then activate manual regeneration. Finally, the outflow of sewage from the valve might be occluded; if so, restore the patency of the washings discharge hose.

  If the salt level in your Viessmann Water Dispenser remains unchanged while it's still supplying water, it could be due to a salt bridge formed in the brine tank. If this happens, remove the salt bridge. Alternatively, the by-pass valve might be in the by-pass position; in that case, set the by-pass valve to the service position.

  If the water from your Viessmann Water Dispenser is periodically hard, several factors could be responsible. Check if the time is set correctly and adjust it if necessary. Also, verify that the programmed raw water hardness value is accurate; if it's too low, determine the correct water hardness and program the appropriate value. Ensure that soft water is not fed during the regeneration process by checking the control panel settings. Finally, check for uncontrolled water leakage and remove all water leakage to avoid excessive water consumption.
