Manufacturer manualDiagnostics code: Setting the pump output
Shared across the ecoTEC pro range
This code is shared by the boilers in this range, which use the same control board. It may not be printed in this exact variant’s manual.
What causes this fault?
This isn't a mechanical failure, but rather a configuration setting that has been accessed or adjusted within the boiler's menu. It happens when an engineer or user enters the diagnostic mode to change the speed at which the pump moves hot water around your radiators. It is used to balance the system's efficiency and noise levels rather than to report a broken part.
