Press OK to start (~45min). ### Can I clear Descaling needed. Press OK to start (~45min) myself? Press OK to start, or choose later if you are mid-morning; the cycle runs about 45 minutes. ### How long does a Bertazzoni descale take? About 45 minutes by the screen's own estimate, including the rinses. Plan it for a time you will be near the machine to refill the tank. ### Can I skip Descaling needed on my Bertazzoni for now? Yes, the screen lets you put it off. Leaving it for weeks lets scale thicken and slow the heater. ### Does a Bertazzoni with the softener filter still need descaling? Yes. The cartridge softens the water but does not replace the descale program, and the cartridge itself runs out and has to be changed or removed when the screen asks. --- **[Read on the site: Bertazzoni Descaling needed: the CM242WTXT asks for its descale cycle](https://coffeemachinerepair.center/error-codes/bertazzoni-descaling-needed/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
