Baxi Boiler Error Codes
A plain-English reference to 8 common Baxi fault codes — what each means, what causes it, and when to call a licensed BC gas technician.
Baxi boilers display an "E" fault code on the digital readout when a safety circuit trips. This reference explains the common Baxi fault codes — such as E119 low pressure, E125 circulation and E133 ignition — with the likely causes and why instrumented gas and combustion faults must be handled by a licensed BC gas technician.
Smell gas? Leave the building immediately and call 911 or FortisBC at 1-800-663-9911 from outside. Never bypass a safety lockout or attempt gas work yourself — in BC it must be done by a licensed gas fitter.

Baxi error codes — FAQ
Why is my Baxi boiler showing an error code?
Baxi boilers display a fault code when a safety circuit detects a problem — for example with ignition, flame, water flow, temperature or venting. The code points to the affected system. The boiler shuts down to protect itself; a licensed technician then diagnoses the true root cause before repair.
Can I just reset my Baxi boiler?
A single reset after a one-off event is usually fine, but repeated resets without fixing the cause can be unsafe — especially for ignition, gas and venting faults — and can cause further damage. If the code returns, switch the boiler off and call GasBoilers.ca at 604-359-1081.
