Dehumidifier tank fills too quickly or not at all compared to expected operation

Safety: Unplug the unit before cleaning.

• Check environment: Very damp spaces (e.g., after flooding) will fill the tank quickly; this can be normal. Very dry spaces will collect little water.
• Clean filter and coils: Dirty components reduce capacity. Clean as per manual.
• Verify room size: Ensure the dehumidifier’s rated capacity matches the room size. An undersized unit will run continuously with slow results.
• Performance check: If collection is abnormally low despite high humidity, follow the steps under “No Dehumidification / Poor Cooling Performance” and consider professional sealed system service.
