Dyson humidifier shows water in the tank but indicates low water or stops as if empty (no specific code)

Safety first: Unplug the unit and remove the tank before inspection.

• 1. Check tank cap valve: Inspect the cap and valve assembly for cracks or stuck components. Press the valve gently to ensure it moves and opens.
• 2. Clean float and sensor: Look into the base for the float or level sensor. Clean with a 1:1 vinegar-water solution and a soft brush to remove slime or scale.
• 3. Reseat tank firmly: Reinstall the tank, ensuring it is fully seated and locked. Listen for water flowing into the base.
• 4. Test operation: Run the unit and observe whether it now recognizes the water level correctly. If the problem persists, the level sensor or tank valve may need replacement.
