Persistent bad odor from inside the multicooker, even when not in use.

Steps:

• Deep clean lid: Remove the silicone gasket, inner lid plate (if removable), steam release valve, and anti-block shield. Wash all removable parts in warm soapy water, rinse, and dry.
• Clean inner pot: Soak and wash the pot thoroughly. If the non-stick coating is heavily scratched or stained, consider replacing it.
• Deodorize: Run a short steam cycle with water and a few tablespoons of white vinegar or lemon slices, then rinse.
• Dry open: Store the cooker with the lid slightly open to allow ventilation.
