Display shows “HOT” and the unit refuses to start another brew immediately after finishing one.

Safety first: Do not attempt to cool the unit with water or by placing it in a cold environment; rapid temperature changes can damage components.

• Allow cool-down: Wait 5–15 minutes after a brew cycle to allow the internal boiler temperature to drop.
• Vent steam: Open the reservoir lid (if safe) to allow steam to escape more quickly, but avoid placing your face or hands over the opening.
• Check for blocked vents: Ensure the machine’s ventilation openings are not blocked by cabinets or other appliances.
• Test again: Once the display no longer shows “HOT,” attempt another brew. If “HOT” appears even when the unit is cold, the temperature sensor may be faulty.
• Sensor fault: A persistent “HOT” message on a cold machine indicates a thermistor or control board issue that requires professional service.
