Strong plastic or chemical smell from a new Ninja coffee maker during its first uses.

Safety first: Ensure good ventilation when running the initial cycles.

Initial cleaning:

• Wash the carafe, brew basket, and removable parts with warm soapy water and rinse well.
• Run 2–3 full reservoirs of plain water through the machine before brewing coffee.

The odor should diminish quickly. If a strong burning or electrical smell persists, stop using the unit and have it inspected.
