FaultFix covers domestic boilers, commercial boilers, and washing machines from every brand engineers and homeowners across Europe actually encounter on the job.
Combi, system, and regular boilers for residential properties across the UK and Europe.
High-output boilers for commercial, industrial, and large residential buildings across Europe.
All major domestic washing machine brands sold and serviced across Europe — front-load and top-load.
Fridges, dishwashers, tumble dryers, heat pumps, and electric cookers are all in development.
FaultFix is built around one goal: get you from a blinking error code to a clear, actionable fix in the shortest time possible.
Open FaultFix and choose your appliance type — boiler, washing machine, dishwasher, or more. Then select your brand from our full list of 30+ manufacturers. FaultFix knows the exact fault code structure for every model.
Type the code showing on the appliance display — exactly as it appears. FaultFix searches its database of 5,000+ codes instantly and finds the exact match for your brand and model.
FaultFix explains exactly what the fault code means — the component involved, the likely cause, and the severity. You'll immediately know if this is something you can handle yourself or if a Gas Safe engineer is required.
Every fault comes with a step-by-step repair guide tailored to your level — simple and safe for homeowners, detailed and technical for engineers. If you prefer to watch, the video fault-finding library has you covered too.
FaultFix launches on Android and iOS. Join the waitlist and get notified the moment it goes live.
No subscriptions required to get started. Upgrade to Pro when you need the full depth professional engineers depend on.
For homeowners who occasionally need to look up a fault code and understand what's wrong with their appliance.
For professional engineers who need full offline access, unlimited lookups, and complete technical depth on every job.
For companies, repair businesses, and trade organisations that need multi-user access, custom integrations, or volume licensing.
FaultFix exists because the way engineers and homeowners find appliance repair information is completely broken — and nobody had fixed it properly for Europe.
Every day, thousands of heating engineers across Europe lose valuable time on jobs hunting for a fault code meaning. They search Google, find outdated forum posts or PDFs written in the wrong language, or end up calling a manufacturer helpline just to be put on hold.
And homeowners have it even worse. A boiler flashes E4 or a washing machine shows 4E and they have no idea if they should panic, call an engineer immediately, or whether it's something they can safely sort themselves in five minutes.
That gap — clear, instant, offline appliance fault information for European brands — is exactly what FaultFix fills.
Most repair apps are built for the US market. FaultFix is designed from the ground up for the UK, Germany, Netherlands, France, and the wider European market — the brands and standards engineers here actually work with.
Professional engineers need technical depth. Homeowners need plain English. FaultFix is the first app that genuinely serves both — same database, two levels of detail, one seamless experience.
FaultFix exists to make appliance repair information instantly accessible to anyone who needs it — professional or not, with internet or without.
Every feature is designed around one question: how do we get the user to the right fix faster? No bloat. No distractions.
An app that doesn't work in a boiler cupboard is useless. FaultFix works everywhere, always — signal or no signal.
We cover the brands, models, and safety standards that matter to engineers and homeowners across Europe — not an afterthought, the whole point.
Join the waitlist and help shape what FaultFix becomes — your feedback matters before we launch.
