Dyson humidifier dehumidifier combo unit blows warm air but does not reduce humidity

Safety first: Unplug the unit before cleaning coils or filters.

• 1. Check room conditions: Dehumidifiers work best above a certain temperature (often above 18°C / 64°F). Very low temperatures reduce performance.
• 2. Clean air filter and coils: Remove and clean the air filter. If condenser coils are accessible, gently clean dust from them.
• 3. Cross-check humidity: Use an external hygrometer to verify humidity levels. If the unit's reading is inaccurate, the humidity sensor may be faulty.
• 4. Professional diagnosis: If airflow is good but humidity does not drop, the sealed refrigeration system may be undercharged or leaking, which requires professional service.
