A fault code is the boiler telling you what it saw before it stopped. Most of the codes Coventry households read off a display come down to two things: the boiler could not light, or the water pressure in the system is too low. Find your brand below. Each page explains the code in plain English, what you can safely check yourself, and when it needs an engineer. Code meanings can differ between model generations, so check the manual that came with your boiler as well.

Boiler Fault Codes — your questions

Is a fault code dangerous?

The code itself means the boiler has stopped safely because it detected a problem. Smell gas? Leave the house, do not use switches, and call the National Gas Emergency line on 0800 111 999. A fault code is never a gas leak, but a smell always is.

Can I just reset it?

Once, yes - the reset button is there for that. If the same code comes back, stop resetting it. Repeated resets can turn a cheap fault into an expensive one.

My code is not listed here.

Write it down exactly as shown, check the manual, and send it with a photo of the display. The code narrows the fault to a part before anyone arrives.
