E3 error on Avanti induction or electronic cooktop, zone will not heat and may beep

Safety first: Disconnect power before opening the cooktop. Induction modules store high voltage; discharge capacitors before handling.

• Check cookware: Ensure you are using flat-bottom, ferromagnetic cookware (a magnet should stick to the bottom). Center the pan on the zone and ensure it covers the minimum area.
• Try another pan: Test with a different known-compatible pan. If E3 clears, the original cookware was incompatible.
• Inspect coil and wiring: With power off and glass lifted, inspect the induction coil for cracks, burnt spots, or broken leads. Check wiring from coil to power module.
• Replace faulty parts: If the coil is damaged, replace the induction coil assembly. If the coil looks good but E3 persists on that zone only, replace the induction power module for that zone.
