What causes this fault?
This occurs when the boiler has been sitting idle for a long period without a request for heating or hot water. To prevent the internal pump and diverter valve from seizing up due to inactivity, the system automatically triggers a brief movement cycle to keep all mechanical components lubricated and moving freely.
This display is most common during the summer months when the central heating is turned off and the boiler is used less frequently.
