Induction or ceramic Etna cooktop shows E2 and shuts down the affected zone.

Safety: Turn off the cooktop and allow it to cool completely before touching any components.

• Remove cookware: Take the pan off the affected zone and let the glass cool until the residual heat indicator turns off.
• Check ventilation: Ensure there is adequate clearance under the cooktop (as per Etna installation manual). Clear dust, grease, or obstructions from intake and exhaust vents.
• Avoid empty-pan heating: Do not run an empty pan on boost or high power; this can trigger E2.
• Reset power: Switch off the circuit breaker for 1 minute, then restore power and test the zone at low power.
• If E2 returns quickly: The NTC sensor or power module heat sink sensor may be faulty. These are mounted on or near the induction coil and heat sink and typically require module replacement.
