Device will shortly be locked.. ### Can I clear Descaling program is overdue. Device will shortly be locked. myself? Start the descaling program, or Clean & Descale, from the service menu right away. ### What is the difference between Descale and Clean & Descale on a Thermador? Descale removes limescale only; Clean & Descale runs the descale and the coffee-oil cleaning in one session. When both are due close together, the combined program saves a second session. ### My Thermador is plumbed. Can I still descale it the normal way? Yes. The TCM24PS guide gives the same descale and Clean & Descale programs as the tank model; follow the display prompts. ### Is the Thermador lock a way to force a service call? No. You release it yourself by completing the descale. A technician is needed only if the lock survives a finished cycle. --- **[Read on the site: Thermador: Descaling program is overdue, device will shortly be locked](https://coffeemachinerepair.center/error-codes/thermador-descaling-program-overdue/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
