Dyson humidifier turns off by itself after a short time, even though the tank is full and settings are normal

Safety first: Unplug the unit before cleaning or inspection.

• 1. Clean vents: Thoroughly clean all air intake and exhaust vents with a soft brush or vacuum. Dust buildup can cause overheating.
• 2. Check placement: Ensure the unit has adequate clearance on all sides (typically at least 30 cm / 12 in) and is not placed in an enclosed space.
• 3. Inspect plug and socket: Wiggle the plug gently in the outlet (with power off) to check for looseness. Try a different outlet.
• 4. Monitor run time: After cleaning, run the unit and time how long it operates before shutting off. If it always stops after a similar interval, an internal sensor or PCB fault is likely.
• 5. Professional diagnosis: Repeated unexpected shutoff despite good airflow suggests a failing temperature sensor or control board that should be replaced.
