Bosch induction cooktop briefly heats then shows E2 and shuts off the zone.

Safety first: Surfaces may be hot. Allow the zone to cool before touching the glass.

• Check cookware: Use a flat-bottomed, induction-compatible pan. A magnet should stick firmly to the base. Ensure the pan size matches the zone diameter.
• Center the pan: Place the pan centrally on the cooking zone. Off-center placement can cause detection errors.
• Reduce power: Try operating at a lower power level to see if the error is related to overheating.
• Inspect for damage: If E2 occurs with proper cookware, the temperature sensor or pan detection circuit on the power module may be faulty and require professional diagnosis and replacement.
