Dehumidifier displays CF after extended operation

Note: CF is typically a maintenance reminder, not a fault.

Steps:

• Remove filter: Take out the air filter from the front or rear grille.
• Clean thoroughly: Vacuum loose dust, then wash with mild soap and warm water. Rinse well and let it dry completely.
• Reinstall filter: Slide the dry filter back into place securely.
• Reset indicator: On many Insignia models, press and hold the Filter or Timer button (check your manual) for 3–5 seconds to clear CF.

Tip: Clean the filter every few weeks in heavy use to maintain efficiency and prevent other error codes.
