Technical description: No Display
What causes this fault?
This fault occurs when the electrical connection between the boiler's internal computer and the front screen is broken or lost. The most common reason is a failure of the display circuit board itself, or a blown fuse on the main control board caused by an internal electrical surge.
DIY fix possible
Check if other appliances in the house are working to rule out a general power cutCheck your home's main fuse box (consumer unit) to see if a circuit has trippedEnsure the boiler's power switch (usually a fused spur near the unit) is turned on
