12:00 flashing (power failure) – Coffee Machine error code

Thermador Coffee Machine error code

12:00 flashing on a U.S. Thermador built-in coffee machine is the officially published indication for power failure or the appliance having been switched off—often after an outage or an unexpected shutoff.
