Unusual plastic or chemical odor from the cooker during use, persisting after several cooking cycles.

Safety first: If the smell is very strong or accompanied by smoke, unplug immediately.

• Initial burn-in: For a new Aroma multicooker, run 2–3 cycles with water and a bit of vinegar to remove manufacturing odors.
• Inspect interior: Ensure no plastic packaging, labels, or utensils are left inside the cooker or under the inner pot.
• Check underside: Remove the bottom cover and look for melted plastic parts near the heating plate. Replace any deformed components.
• Avoid harsh chemicals: Do not use strong solvents or abrasive cleaners inside the cooker; residues can produce odors when heated.
• Ventilate: Use the cooker in a well-ventilated area until odors dissipate. If the smell worsens over time, discontinue use and have the unit inspected.
