Dehumidifier runs but does not collect water; room remains humid.

Safety warning: The sealed refrigerant system must only be serviced by certified refrigeration technicians. Do not attempt to cut or open refrigerant lines.

User-level checks:

• Verify settings: Ensure the humidity setpoint is below current room humidity and that the unit is in dehumidify mode, not fan-only.
• Check temperature: Dehumidifiers are less effective at low temperatures (below ~15°C). Move the unit to a warmer room if necessary.
• Clean filters and coils: Dirty filters and coils reduce performance. Clean both thoroughly.
• Observe coil behavior: After 15–20 minutes of operation, the evaporator should be cool and may have a light, even frost pattern in very humid conditions. If it remains warm or only a small section cools, the refrigerant charge may be low or the compressor weak.
• Professional service: If airflow is good and settings are correct but no water is collected over several hours, contact an authorized Argo service center to check the Argo compressor and sealed system for leaks and performance.
