Burning smell or visible smoke from the coffee maker.

Safety first: Unplug the coffee maker immediately. If there is active smoke or fire, follow emergency procedures and do not attempt repairs until safe.

• Do not reuse: Do not plug the appliance back in until the source of the burning smell is identified and corrected.
• External cleaning: Once cool, clean any burnt coffee or debris from the hot plate and around the filter area.
• Internal inspection (advanced): Remove covers and inspect wiring, the aluminium heating block, and the PCB for burn marks or melted components.
• Replace damaged parts: Any burnt wiring, connectors, or components must be replaced. If the PCB is charred, replace the entire board.

Because of fire risk, significant burning or smoke damage should be handled by a professional or the appliance should be replaced.
