Dehumidifier emits a musty or moldy odor from the air outlet.

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

Steps:

• Clean filter: Wash the air filter with mild detergent and dry completely.
• Access coils and pan: Remove front/rear panels to expose the evaporator coil and drain pan.
• Clean surfaces: Use a coil-safe cleaner or a mild solution of water and a small amount of household detergent. Do not soak electrical components.
• Flush drain: Pour a small amount of diluted bleach solution (per manufacturer guidance) through the drain to kill mold and clear slime.
• Drying: Allow components to dry before reassembly.

Regular maintenance and running the fan-only mode periodically can help prevent odors.
