Induction cooktop shows F0E3 when a burner is turned on, no heating

Safety first: Surface may still be hot; allow to cool before touching.

• Check cookware: Use a magnet on the bottom of the pan; it must stick firmly for induction. If not, use induction-compatible cookware (ferromagnetic stainless steel, cast iron).
• Pan size and position: Ensure the pan fully covers the marked cooking zone and is centered. Very small pans may not be detected.
• Flatness: Use a straightedge to check that the pan bottom is flat. Replace heavily warped pans.
• Internal fault: If compatible cookware is used correctly and F0E3 persists only on one zone, the pan detection circuit in that coil or module may be faulty and require professional replacement.
