Coffee maker emits a burning smell during brewing.

Safety first: Turn off and unplug the coffee maker immediately. Do not continue to operate if you smell burning plastic or wiring.

• Inspect exterior: Once cool, check the warming plate and exterior surfaces for burnt coffee or spills and clean thoroughly.
• Descale: Perform a descale cycle to reduce heater stress if the smell is more like burnt coffee than plastic.
• Check cord and plug: Inspect for discoloration or melting. If present, do not use the machine.
• Do not open housing: Internal burning smells often indicate wiring or component failure and require professional inspection.
• Service required: If the smell persists after cleaning and descaling, have the unit inspected by a technician before further use.
