Humidifier shows F1 and stops producing mist

Safety: Unplug the Cecotec humidifier before handling the water tank or internal parts.

Steps:

• Refill and reseat tank: Fill the tank with clean water up to the indicated level. Ensure the tank is properly seated and the cap is tightened if the design uses an inverted tank.
• Check float: If the model uses a float in the base, verify it moves freely up and down. Clean any scale or slime that may cause sticking.
• Clean electrodes: For electronic level sensors, gently clean the metal probes with a soft cloth and white vinegar to remove mineral deposits.
• Reset: After cleaning and refilling, plug the unit back in and restart. If F1 clears, monitor operation.
• Replace sensor: If F1 persists with a full, correctly seated tank, the level sensor or float switch may be defective and should be replaced with a Cecotec-compatible part.
