What Does Error OVERHEATING Mean?
The Bosch cooktop error OVERHEATING indicates that the cooktop has triggered its automatic overtemperature protection state. This occurs when the heating element generates excessive heat, leading to the automatic shutdown of affected cooking zones to prevent damage. Symptoms include zones shutting off, warning messages on the display, and hot surfaces or internal electronics. The cooktop will not reactivate until it cools down sufficiently.
Common Symptoms:
- Affected cooking zone(s) shut off automatically
- Error indication or warning message on display
- Cooktop surface or internal electronics hot to touch
- Zones won’t reactivate until cooled
Possible Causes
- Automatic overtemperature protection triggered (high)
- Hot cookware or residual heat near the control panel (medium)
