Bodum coffee maker emits a burnt plastic or electrical smell during operation.

Safety first: Unplug the coffee maker immediately. Do not continue using it until the source of the smell is identified.

Steps to try:

• Inspect hot plate: Once cool, clean any spilled coffee or sugar from the hot plate. Burnt residue can smell like burning plastic.
• Check cord and plug: Look for discoloration, melting, or cracks. Replace the cord set if damaged.
• Internal inspection (advanced): Remove the bottom cover and look for browned plastic, melted wire insulation, or scorch marks near the heater and control board.
• Tighten connections: Reseat any loose spade connectors on the heater and switch. Loose connections can overheat and arc.

If you find melted components or burnt PCB areas, discontinue use and replace the affected parts or the entire unit.
