Dehumidifier emits a musty or moldy odor during operation.

Safety: Unplug the unit before cleaning. Wear gloves and, if sensitive, a mask when dealing with mold.

Steps to remove odor:

• Clean bucket: Wash the water bucket with warm water and mild detergent. Disinfect with a diluted bleach solution (1 tablespoon bleach per gallon of water). Rinse thoroughly.
• Clean air filter: Wash and dry the filter to remove dust and odor-causing particles.
• Clean coil and drain pan: Remove the front cover and gently vacuum dust from the evaporator coil. Spray a coil-safe cleaner or a mild disinfectant on the coil and drain pan, avoiding electrical components.
• Flush drain hose: If using a hose, flush it with a bleach solution and then rinse.
• Run on fan-only: After cleaning, run the unit on fan-only mode for 30–60 minutes to help dry internal surfaces.
