Switch the machine off at the main switch and let it cool. If it comes back, it needs a visit. ### Which switch does the Gaggenau mean by switch off? The main switch that cuts power to the machine, not just a standby touch. That full restart is what the screen asks for. ### How often should the Gaggenau brewing unit come out for cleaning? Gaggenau's newer manual suggests once a week on top of the automatic rinse. The older CMP 250 benefits from the same habit. ### Can this Gaggenau screen mean the brewing unit drive is wearing? If it keeps coming back with a clean unit and a cool machine, yes, the drive or its sensing is a likely suspect for the technician. --- **[Read on the site: Gaggenau CMP 250: Switch off appliance](https://coffeemachinerepair.center/error-codes/gaggenau-switch-off-appliance/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
