Water heater fault-code lookup
Enter the brand (if you know it) and the code, number or flash pattern your water heater shows. You get the documented meaning from the manufacturer's manual when this site has verified it, or an honest “not recorded yet” with the fastest way to get it checked.
A code is a starting point, not a diagnosis
Every code page on this site states which series, control platform and manual version it was read from. The same number can mean different things on different brands, which is why the lookup asks which equipment shows it. If you smell gas or a carbon-monoxide alarm sounds, do not use this tool: leave the building and call FortisBC at 1-800-663-9911 or 911 first.Need a technician now? Fault-code lookup: code unknown.
