The dehumidifier has a musty or moldy odor from the air outlet.

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

Steps:

• Clean bucket: Remove the water bucket and scrub it with warm water and a mild bleach solution (1 tablespoon bleach per gallon of water). Rinse thoroughly.
• Clean filter: Wash the air filter with soap and water and let it dry completely.
• Access coil and drain: Remove the front panel to expose the evaporator coil and drain trough. Wipe accessible surfaces with a coil-safe cleaner or mild detergent solution.
• Flush drain: Pour a small amount of diluted bleach solution through the drain channel to kill biofilm, then flush with clean water.
• Drying run: After reassembly, run the unit in a dry, well-ventilated area for several hours to help clear residual odors.
• Regular maintenance: Empty and rinse the bucket daily during heavy use and clean the filter monthly.
