Coffee maker emits a burning smell during brewing or warming.

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

• Inspect hot plate: Once cool, clean the Tristar warming plate thoroughly to remove burnt coffee spills or sugar.
• Check for foreign objects: Look under and around the machine for trapped packaging, paper, or plastic that may be touching hot surfaces.
• Internal inspection (advanced): Remove the bottom cover and look for discolored or melted wiring, especially near the heater and hot plate thermostat. Replace any damaged wiring and secure away from hot surfaces.

Warning: If the smell persists or you see smoke, discontinue use and have the unit inspected by a professional. Fire risk is possible.
