Technical description

Blank Display.

What causes this fault?

This fault occurs when the boiler's control system loses electrical power or the communication between the internal components is broken. The most common reasons are a blown internal fuse caused by a temporary power surge or a hardware failure within the main circuit board or display screen.

This issue can be more common during the winter months or during stormy weather, when power fluctuations and grid surges are more likely to occur.

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.
