What to do if Viessmann Water Dispenser supplies water that is too hard?
- YykellerAug 9, 2025
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.
