Coffee is not hot enough immediately after brewing.

Safety first: Unplug before descaling or cleaning.

• Preheat carafe: Rinse the carafe with hot tap water before brewing to reduce heat loss.
• Descale: Run a full descale cycle with a 1:1 vinegar-water solution to remove scale that insulates the heater.
• Check outlet voltage (technician): Low line voltage can reduce heater performance; an electrician can verify this.
• Evaluate temperature: If coffee remains lukewarm after descaling, the thermostat or heater may be failing and require professional replacement.
