Induction cooktop does not heat; display shows E0 or a blank power level when a pan is placed.

Safety first: Induction cooktops operate at high voltage; do not open the glass or internal panels unless power is disconnected at the breaker.

• Check cookware: Use a flat-bottomed, ferromagnetic pan (a magnet should stick firmly to the base). Ensure the pan diameter matches or exceeds the marked cooking zone.
• Center the pan: Place the pan centrally on the zone and select a medium power level. If E0 persists only with certain pans, the issue is likely cookware-related.
• Test other zones: Try the same pan on other induction zones. If only one zone shows E0, that zone's coil or sensor may be faulty.
• Internal inspection (advanced): With power off and glass removed, inspect the affected zone's induction coil and sensor wiring for cracks, burns, or loose connectors.
• Module replacement: If the coil is physically damaged or the detection circuit on the power module has failed, replace the induction power module for that zone.

Note: Slightly warped pans or those with sandwich bases may not be recognized reliably; test with a known-good cast iron or fully magnetic stainless pan.
