Induction zone will not heat, display shows E1 when attempting to use the zone

Safety: This troubleshooting is external only. Do not remove the glass or open the cooktop while energized.

• Test with known good pan: Use a flat, heavy-bottomed stainless steel or cast iron pan that a magnet sticks to firmly. Center it on the affected zone.
• Check pan size: Ensure the pan diameter matches or slightly exceeds the inner ring of the cooking zone. Very small pans can trigger E1.
• Check pan contact: Avoid warped or rounded-bottom pans. The base must sit flat on the glass.
• Try another zone: If the same pan works on other zones but not on one specific zone, the issue may be with that zone’s induction coil or sensor.
• Power reset: Turn the cooktop off at the breaker for 2–3 minutes and retest.
• If only one zone always shows E1 with good cookware: A technician should test the induction coil and power module for that zone and replace as needed.
