BoilerFaultCodesTechnical description
Purging programme is running. The purge programme is activated.
What causes this fault?
This occurs when your boiler detects air trapped within the internal heat exchanger or pipework, often following a service, a repair, or after the system has been drained and refilled. The boiler automatically pauses its normal heating cycle to run the pump and internal valves to push these air bubbles toward the automatic air vent. Once the system is satisfied that the air has been purged, the boiler will return to normal operation on its own.
This code is most common in autumn when homeowners turn their heating back on for the first time or after summer maintenance work has been carried out on the radiators.
DIY fix possible
Wait approximately 5 to 7 minutes for the cycle to complete automaticallyEnsure your radiator valves are open to help move air through the systemCheck that the system pressure is between 1.0 and 1.5 bar on the display
