Induction or electronic cooktop zone displays E2 and will not operate

Safety first: Turn off the cooktop. Do not touch the hot glass; wait until the surface cools.

• Remove spills: Once cool, clean the glass thoroughly with a cooktop cleaner, especially around the affected zone.
• Ventilation check: Confirm that there is adequate airflow under the cooktop and that insulation or stored items are not pressed against the underside.
• Power reset: After cleaning and cooling, turn the breaker OFF for 1 minute, then ON, and test the zone at a moderate power level.
• Sensor/module fault: If E2 returns quickly at low power and the glass is not excessively hot, the surface temperature sensor or induction module may be defective and require replacement.
