Humidifier runs but no visible mist or humidity increase in the room.

Safety first: Unplug the humidifier before cleaning or disassembly.

Steps to restore humidification:

• Check water level: Ensure the tank is full and properly seated so water flows into the base.
• Descale components: For ultrasonic models, gently clean the transducer with a soft cloth and white vinegar to remove mineral deposits. For evaporative models, inspect and replace the wick filter if hardened or discolored.
• Clean mist outlet: Remove any mineral crust or dust from the mist outlet and internal passages.
• Verify fan operation: Confirm the fan is running and drawing air through the unit. Replace the fan motor if not operating.
• Transducer replacement: If the ultrasonic disc does not vibrate or produce mist even with clean surfaces, replace the ultrasonic transducer assembly.

Warning: Always use the type of water recommended by Electrolux (often distilled) to minimize scale buildup.
