Manufacturer manualTest programme where the appliance is operated in full load after successful ignition.
What causes this fault?
This isn't actually a fault, but rather a temporary status code triggered when the boiler is performing a safety and performance check. After ignition, the control system forces the boiler to run at its highest power setting to verify that the gas valve and fan are operating correctly. Once the internal sensors are satisfied that the burner is stable at full capacity, the code will disappear and the boiler will return to normal operation.
