Bosch HDI8056U 800 Series 30 in Induction Slide-In Range Er1 Error Fix: Induction Coil Overheated

Error code Er1 on the Bosch HDI8056U 800 Series 30 in Induction Slide-In Range means: Induction Coil Overheated. An induction heating coil has exceeded its maximum temperature. The cooktop has shut down the affected zone to prevent damage. Allow the unit to cool completely. Ensure the ventilation openings under the cooktop are not blocked — induction cooktops have internal fans that require adequate airflow. Check the cooling fan operation. If the fan is not running, check the fan motor and wiring. Using oversized cookware that extends beyond the cooking zone can cause localized overheating.
