Induction hob beeps and shows E1 when attempting to use a cooking zone.

Safety first: Ensure the hob surface is cool before handling pans. Do not use damaged cookware.

• Check pan compatibility: Use a magnet on the base of the pan. If it does not stick firmly, the pan is not suitable for induction and will trigger E1.
• Match pan to zone size: Ensure the pan base covers at least 60–70% of the marked cooking zone. Very small pans may not be detected.
• Check pan base flatness: Place the pan on a flat surface and see if it rocks. Warped pans can cause intermittent detection; replace if necessary.
• Clean the glass: Wipe the zone with a soft cloth and mild detergent to remove grease or residue that may interfere with detection.
• If E1 appears with all suitable pans: The pan detection circuit on the induction coil module may be faulty. Power off at the mains and arrange service.
