Possible Causes

Safety first: Allow the machine to cool before restarting.

Check ventilation: Ensure vents are not blocked and that built-in units have the required clearance.
Inspect power connection: Make sure the plug is fully inserted and not loose in the outlet.
Reduce duty cycle: Avoid making many drinks back-to-back without short pauses.
If shutdowns persist: A failing thermal cut-out or power supply may be the cause; contact Bosch service.
