Water level in the kettle or brewer appears to drop without visible leaks (steam loss).

Safety first: Beware of hot steam; unplug before close inspection.

• Check lid seal: Ensure the lid is fully closed and gasket is intact.
• Inspect steam vents: Make sure vents are not blocked and are directing steam away from sensitive areas.
• Monitor boil behavior: If the unit boils vigorously for long periods, adjust usage or have the thermostat checked.
