Electric Bialetti coffee maker emits a burning smell during operation.

Safety first: Turn off and unplug the machine immediately if you smell burning. Do not continue using it until the cause is identified.

• Inspect exterior: Look for coffee or milk spills on the hot plate or heater area and clean thoroughly once cool.
• Check underside (advanced): Remove the base cover and inspect for melted plastic, burnt wiring, or debris near the heater.
• Clean interior: Remove any foreign objects or accumulated dust from around the heater and vents.
• Do not ignore persistent smell: If the burning smell continues after cleaning, discontinue use and have the machine inspected professionally.

Burning smells can precede serious failures; address them promptly.
