Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the unit before cleaning or inspection.
Steps to improve dehumidification:
- Clean the air filter: Remove and wash the filter with mild soap and water. Dry completely before reinstalling.
- Clean coils: Access the evaporator (cold) and condenser (warm) coils. Use a soft brush and vacuum to remove dust and lint from the fins.
- Check room conditions: Ensure doors and windows are closed and major moisture sources (boiling water, open bathrooms) are minimized.
- Verify fan operation: Confirm that the fan runs at full speed and airflow from the outlet is strong.
If the unit still fails to collect water after thorough cleaning and proper room setup, the sealed refrigeration system or compressor may be failing and should be diagnosed by a certified technician.
