Humidifier runs but produces little or no mist.

Safety first: Unplug the humidifier before cleaning. Do not use abrasive tools on the transducer.

• Check water level and tank: Ensure the tank is full and properly seated on the base so water flows into the reservoir.
• Clean transducer: For ultrasonic Haier humidifiers, gently clean the metal transducer disc with a cotton swab dipped in white vinegar to remove mineral deposits. Rinse and dry.
• Clean mist outlet: Remove any mineral crust or dust from the mist outlet and internal channels.
• Use distilled water: To prevent future buildup, use distilled or demineralized water.
• Module replacement: If there is still no mist after cleaning and proper water level, the ultrasonic module or heater assembly may be faulty and require replacement.
