What this means
The air filter needs cleaning; this is a maintenance reminder, not a fault code.
What you can check yourself
- Switch off power before cleaning.
- Vacuum or rinse the air filter with water, then dry it thoroughly in the shade.
- After cleaning, hold the FAN button on the switched-off remote until the indoor unit beeps to reset the reminder.
