Can I reset my Slant/Fin boiler to clear the Ignition Failure code?

You can reset once if your manual says it's safe. If the code returns, stop resetting — repeated resets on a genuine fault, especially gas or overheat faults, can be unsafe and may worsen the problem. Book a licensed repair instead.

Is the Ignition Failure fault dangerous?

Treat it as urgent. This code involves systems where continued operation can be unsafe. Turn the boiler off if it keeps recurring and call for a licensed repair; if you smell gas, leave and call your gas utility's emergency line.

How much does it cost to fix a Slant/Fin Ignition Failure fault?

Cost depends on the underlying cause — some causes (like low pressure or a dirty sensor) are minor, while others (like a gas valve or control board) cost more. We diagnose first and give you a clear price before any repair.

If your Slant/Fin combi boiler is showing error code Ignition Failure, here's what it means: The boiler failed to establish a flame and locked out. This is an urgent fault.

Slant/Fin boilers report faults using error codes on the vhs victory combi and chs wall-hung display. Knowing the code helps a technician arrive prepared with the right parts, which usually means a faster, lower-cost repair.

What causes the Ignition Failure code?

Error Ignition Failure on a Slant/Fin boiler is most commonly caused by one of the following:

No or low gas supply
Igniter or electrode fault
Gas valve fault
Air in the gas line

What you can safely check first

Note the exact code and your boiler's model number
Check the pressure gauge — low pressure triggers many faults
Confirm the gas supply is on and other gas appliances work
Reset the boiler once, per the manual, only if it's safe to do so
If the code returns, stop and call a licensed technician

Why this needs a licensed technician

Resolving a Ignition Failure fault almost always involves the gas, combustion, sensor or pressurized side of the appliance. Under BC's Safety Standards Act, that work must be performed by a licensed gas fitter — and doing it correctly protects your warranty and your safety. We diagnose Slant/Fin boilers, carry common parts, and verify clean combustion before returning your boiler to service.

Smell gas or suspect carbon monoxide? Leave now.

If you smell gas, hear hissing, or your CO alarm sounds, leave the building immediately and call your gas utility's emergency line from outside. Do not operate switches or relight the appliance. Once you are safe, call us for a licensed repair.
