Unit runs in dehumidify mode but produces little or no water.

Steps:

• Check humidity: Use a hygrometer to verify room humidity. If already below about 50%, little water will be collected.
• Clean filters and coils: Ensure good airflow across the evaporator.
• Temperature: Dehumidify mode is less effective at low room temperatures. Use cooling mode or raise room temperature slightly.
• Professional check: If the unit neither cools nor dehumidifies effectively, have a technician check the refrigeration system.
