Klarstein coffee maker emits a burning smell or visible smoke during operation.

Safety first: Immediately unplug the machine. If smoke continues, move it to a safe, non-flammable area. Do not continue using until fully inspected.

External cleaning:

• Once cool, clean any spilled coffee, milk, or sugar from the warming plate and exterior surfaces.

Internal inspection (advanced):

• Remove covers and look for burnt wiring, melted plastic, or charred PCB areas.
• Check around the heater, warming plate, and power entry for damage.

Any burnt wiring or components must be replaced. If the main PCB or heater is damaged, replacement is required. For safety-critical faults, professional service is strongly recommended.
