Induction hob shows E1 on one or more zones and will not heat.

Safety first: Ensure the hob surface is cool before handling cookware.

Steps to check:

• Check pan material: Use cookware with a magnetic base (cast iron or induction-compatible stainless steel). Test with a magnet.
• Pan size: Ensure the pan base is at least 60–70% of the zone diameter. Very small pans may not be detected.
• Pan base flatness: A heavily warped or rounded base can prevent proper detection. Try a different pan.
• Remove barriers: Do not use hob covers, silicone mats, or multiple layers of paper between the pan and glass.
• Try another zone: If the same pan works on other zones, the issue may be with the specific coil or sensor (see F7/F9 entries).
