Can I reset my Super Hot boiler to clear the No Heat / Ignition Lockout 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 No Heat / Ignition Lockout 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 Super Hot No Heat / Ignition Lockout 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 Super Hot combi boiler is showing error code No Heat / Ignition Lockout, here's what it means: The boiler attempted to fire but no flame was proven, so it locked out for safety. This is an urgent fault. Stop using the boiler if it keeps recurring and book a licensed repair promptly — especially if it involves gas, ignition, overheating or the flue.

Super Hot boilers report faults using fault indications on high-efficiency super hot models (older cast-iron units use a thermostat/aquastat rather than digital codes). Knowing the code helps a technician arrive prepared with the right parts, which usually means a faster, lower-cost repair.

What causes the No Heat / Ignition Lockout code?

Error No Heat / Ignition Lockout on a Super Hot boiler is most commonly caused by one of the following:

No or low gas supply
Igniter or flame-sensor fault
Gas valve fault
Tripped safety control

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 No Heat / Ignition Lockout 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 Super Hot 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.
