Thermal carafe does not keep coffee hot for long

Safety: Handle glass-lined thermal carafes carefully to avoid breakage.

• Preheat carafe: Rinse the carafe with hot water before brewing to improve heat retention.
• Check lid seal: Ensure the lid is fully tightened and the gasket is intact. Replace the lid gasket if it is cracked or hardened.
• Test insulation: Fill the carafe with hot water, close the lid, and check temperature after 1–2 hours. If it cools rapidly, the vacuum insulation may be compromised.
• Replace carafe: If insulation has failed, the thermal carafe must be replaced; it is not repairable.
