The refrigerant-leak sensor has started detection. With warning beeps, a refrigerant leak is possible; without beeps, detection may be in progress or may have been triggered falsely by aerosols or hairspray.
When to call a technician
This fault involves refrigerant, pressure, or electrical work that must be handled by a certified technician under EU F-gas rules. Do not attempt to open the refrigerant circuit, access mains wiring, or adjust pressure components yourself. Contact a qualified installer or servicer for this one.
