What causes this fault?

This fault occurs when the boiler's internal computer brain fails to communicate properly with the other electrical components. It is physically caused by a data processing error on the main circuit board or a loose connection in the wiring that prevents the system from safely managing the heating process.

Engineer required

This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
