Dehumidifier runs but collects very little water compared to before.

Safety first: Unplug the unit before cleaning.

• Clean air filter: Remove and wash the filter with mild soap and water. Let it dry completely before reinstalling.
• Clean coils: Access the evaporator and condenser coils and gently brush or vacuum off dust and lint. Avoid bending the fins.
• Check room size and conditions: Ensure the dehumidifier capacity matches the room size and humidity level. Oversized spaces may overwhelm a small unit.
• Inspect for icing: If the evaporator ices up quickly, airflow or refrigerant issues may be present. Defrost the unit and improve airflow.
• Service if needed: If performance remains poor after cleaning and proper sizing, a weak compressor or partial restriction may be the cause; contact a technician.
