Switch the machine off and leave the door closed for thirty minutes. If it comes back, it needs a visit. ### My Bosch built-in overheats only when we make drinks for guests. Is that normal? A long run of drinks is the classic trigger. Spacing them out, or pausing when the message appears, is all Bosch asks. ### Can the cabinet around the Bosch BCM8450UC make it run hot? It can if the installation leaves no path for air. A technician can check the niche against Bosch's installation instructions without removing the machine unless a repair calls for it. ### What if my Bosch built-in says it is too hot when it has been off all night? Then the temperature reading itself is suspect, not the machine's heat. That calls for a visit to test the sensor and the board. --- **[Read on the site: Bosch BCM8450UC built-in: Please allow machine to cool](https://coffeemachinerepair.center/error-codes/bosch-please-allow-machine-to-cool/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
