Run the appliance's own descale program using Wolf's descaling solution, not vinegar or another household product. If it comes back, it needs a visit. ### How often does Wolf recommend descaling? Wolf's own guidance gives a range of every 6 to 18 months depending on usage and water hardness, rather than a single fixed interval for every household. ### Can I use vinegar instead of Wolf's descaling solution? No. Wolf's own support answer specifically warns against vinegar, since it does not descale as effectively and lacks the corrosion protection the maker's own solution provides. ### What if the water tank needs refilling more often than usual? Wolf's own guidance lists frequent refilling as a possible sign that descaling is due, so treating that as an early cue can head off the display message appearing at all. --- **[Read on the site: Wolf boiler scaled up — descale reminder](https://appliancemaintenance.center/error-codes/wolf-boiler-scaled-up/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
