F6 error; compressor may not start or may shut down; sometimes accompanied by unusual compressor noise

Critical: Refrigerant handling must be done by an F-gas certified technician. Do not attempt to open the sealed system yourself.

• Visual inspection: Look for oil stains on the indoor and outdoor coils and connections of your Olimpia Splendid unit, which can indicate leaks.
• Check airflow: Ensure filters and coils are clean and fans are operating correctly; poor airflow can mimic low-pressure conditions.
• Reset power: Turn off the unit for 10 minutes and restart. If F6 returns quickly, a genuine refrigerant or sensor issue is likely.
• Professional service: Contact an authorized Olimpia Splendid service center to perform leak detection, pressure checks, and recharge if necessary. They can also test/replace the low-pressure switch or sensor.
