Hansa oven emits a strong burning smell or smoke during normal cooking (not first use).

Safety first: If heavy smoke appears, turn off the oven, open windows, and keep the door closed until smoke subsides. Do not leave the oven unattended.

• Inspect interior: Once cool, remove racks and check for heavy grease or burnt-on food, especially on the bottom and near elements.
• Deep clean: Use a suitable oven cleaner or the oven's catalytic/pyrolytic function (if equipped) following the Hansa manual. Avoid spraying cleaner directly on elements or sensors.
• Check door seal: Ensure the gasket is intact to prevent grease vapor from entering insulation.
• Persistent smell: If the smell persists after thorough cleaning, insulation may be saturated with grease, which may require professional replacement.

When to call a technician: If smoke appears from behind panels or there are signs of burning wiring, disconnect power immediately and seek service.
