Display shows CF or CLF; filter cycle or clean filter reminder.

Safety first: Turn off power at the breaker before removing the filter to avoid entrapment risk.

• Remove and clean filter: Take out the filter cartridge and rinse thoroughly. Use a filter cleaner solution for heavy buildup.
• Inspect for damage: Replace the filter if the end caps are cracked or pleats are deformed.
• Reset reminder: Follow the topside instructions (often holding a specific button) to reset the CF reminder after cleaning.
