Induction cooktop powers on but all zones show a pan symbol flashing and will not heat.

Safety first: Keep hands away from hot surfaces; no internal access is needed for basic checks.

• Use correct pans: Ensure cookware is induction-compatible (magnetic base) and of adequate size for the zone.
• Center the pan: Place the pan centrally on the marked zone.
• Try different cookware: Test with another known-compatible pan.
• Internal fault: If all zones fail with correct cookware, the pan detection circuitry on the control or power modules may be faulty and require professional replacement.
