Renting? Report it to your landlord or housing provider first. They are responsible for gas safety and boiler repairs, and the repair should not cost you.
What E.04.08 means
E.04.08 indicates that the maximum safe temperature has been reached.
Safe check
Let the boiler cool and record the exact code from the display. Do not remove the casing or attempt an internal reset or repair.
When to contact an engineer
The code remains or returns after the boiler has been safely restarted once.
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.
