Display shows CF after extended use; unit may still operate normally.

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

Steps:

• Clean the filter: Remove the front grille, slide out the air filter, and wash it with warm, soapy water. Rinse thoroughly and let it dry completely before reinstalling.
• Reset the indicator: Press and hold the FILTER RESET or TIMER button (varies by model) for several seconds until CF clears from the display. Refer to the Hotpoint user manual for the exact reset procedure.

Tip: Clean the filter every few weeks during heavy use to maintain efficiency and prevent icing or airflow issues.
