Dehumidifier has a musty or moldy smell from the air outlet

Safety: Unplug the unit. Wear gloves and a mask if you are sensitive to mold.

Steps:

• Clean bucket: Wash the water bucket with warm soapy water and a small amount of bleach. Rinse thoroughly.
• Access coils and pan: Remove front cover and bucket to expose the evaporator coil and drain pan.
• Clean drain pan: Scrub the pan with a mild bleach solution or coil cleaner designed to remove biological growth. Rinse carefully without flooding electrical parts.
• Coil cleaning: Use a foaming coil cleaner safe for aluminum fins. Follow product instructions and allow to drain into the pan.
• Drying: Let the unit air dry completely before reassembly. Running the fan-only mode for a while after use can help keep it dry in the future.

Tip: Regular cleaning every few months reduces odors and improves air quality.
