Dehumidifier runs but collects very little water compared to before

Safety: Unplug before cleaning internal components.

Steps:

• Verify conditions: Use a hygrometer to confirm room humidity. If RH is already low (below ~45%), water collection will naturally be minimal.
• Clean filter: Remove and wash the air filter. Let it dry fully before reinstalling.
• Clean coils: Remove front and rear covers as needed to access coils. Carefully brush off dust and use a non-corrosive coil cleaner if heavily soiled.
• Check airflow: Ensure intake and exhaust are not blocked by walls, curtains, or furniture.
• Observe coil behavior: After 15–20 minutes of operation, the evaporator should be evenly cool. If only a small section is cold or frosted, the sealed system may be partially restricted or low on refrigerant.

When to call a technician: If cleaning does not restore performance and the unit is still under warranty, contact Insignia support. Sealed system issues require professional service.
