Technical description: Text display not detected.
What causes this fault?
This fault occurs when the boiler's main internal computer loses its connection with the digital screen on the front of the unit. The most common reason is a loose or damaged ribbon cable that transmits data between the two components, or a electronic failure within the display board itself. Essentially, the 'brain' of the boiler is still working, but it can no longer send information to the screen you see.
DIY fix possible
Press the Reset button for five secondsTurn the main power switch to the boiler off and then back on againCheck if the display panel is firmly clicked into its housing
