What E.04.54 means
E.04.54 indicates a fault in the gas valve control circuit.
Safe check
Record the exact code from the display and do not remove the casing or attempt any gas-valve checks.
When to contact an engineer
The code is displayed or returns; this fault requires a qualified engineer to investigate.
Safety notice
A boiler fault code alone is not a gas or carbon-monoxide emergency. If you smell gas, a CO alarm sounds, anyone feels unwell, or there is an unsafe flame, leave and call 0800 111 999 from outside.
