What this means
The evaporating pressure measured by the low-pressure switch is too low; it should remain above 1.5 bar. Possible causes include low airflow, a dirty filter, refrigerant loss, an expansion-valve fault, or an interrupted alarm circuit.
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.
