About Fault Code Check
A fault-code reference written by somebody who got tired of scrolling past 600 words of preamble to find out whether his boiler was safe to leave on.

Why this exists
Your boiler flashes a code at seven in the morning in January. You search it. You land on a page that spends 600 words explaining what a boiler is before it tells you anything, or on a forum thread from 2014 where nobody agreed. Meanwhile you still do not know whether it is safe to leave it on.
We built the site we wanted to find that morning. Every fault code page answers the same five questions in the same order: what the code means, whether it is dangerous, what causes it, what you can safely try, and what a repair costs. The answer is the first sentence on the page, not the last.
Who writes it
Andrew Pickett, and his name is on every page for the ordinary reason that you should be able to see who told you something before you act on it.
He is not a heating engineer and does not claim to be. What he does is narrower: every page here is written from the manufacturer's own installation, servicing and user documentation for that appliance, and where the manufacturer has published nothing about a code, the page says so rather than borrowing a meaning from elsewhere. His page sets out the method, including the pages it has caught this site getting wrong.
Who runs it
The site is operated by Omega IT (OmegaIT Limited, company no. 135506C), an IT support business in Douglas, Isle of Man, and Fault Code Check is its trading name. The postal address is on the contact page and at the foot of every page. Omega IT is not a heating or appliance business and holds no trade registration. Naming it tells you who is accountable for the site; it does not change a word of what the sections below say about review.
What we will not do
We do not host manufacturer manuals or copy their wording. We establish the facts from technical documentation and then write the explanation ourselves.
We do not tell you to do something dangerous because it makes for a better page. If a fault involves gas, combustion, a flue, or the inside of a sealed unit, we say plainly that it needs a registered engineer and we do not publish steps for it. That costs us traffic. It is not negotiable.
We do not pretend to be a manufacturer or an approved repairer. We are not affiliated with any brand named on this site. We use brand names only to identify which appliance a code belongs to.
How we pay for it
Three ways, and we would rather tell you than have you work it out. Some pages show advertising. Some parts links earn us a commission if you buy through them — we mark those clearly and it never changes what you pay. And where a page offers to find you an engineer, that request goes to a vetted repair partner who pays us for the introduction; where we have no partner for a trade, the page points you to the trade's own register instead and takes no details from you.
None of that changes what a page says. Severity ratings and safety advice are never adjusted for commercial reasons, and nobody can pay to have a fault described as less serious than the manufacturer describes it.
What we are not
We are not a substitute for an engineer, and we are not reviewed by one. No page on this site has been read by a registered engineer — not for gas, domestic appliances, refrigerant work or electrical installation — and rather than imply a sign-off that has not happened, every page says so plainly, beside the name of the person who wrote it and the documents it was written from. How we verify sets out exactly what that means.
