BoilerFaultCodesYour boiler is currently set to a specific testing or maintenance mode and is not running in its normal automatic state.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Service Function: Pump control mode
What causes this fault?
This code appears when the boiler has been manually put into a specific service setting by an engineer, which changes how the internal pump operates. It is caused by an installer navigating the diagnostic menu and leaving the pump control function active rather than returning it to the standard automatic setting. Because this is a configuration setting rather than a broken component, the boiler is simply waiting for a command to return to normal operation.
DIY fix possible
Locate the 'Service' or 'Wrench' button on the control panelPress and hold the service button until the display returns to the standard temperature outputTurn the power off and back on at the fused spur switch to reset the electronics
