You may attempt to reset the boiler once to see if the fault clears. In some cases, the error may appear due to a temporary system interruption. If the fault code clears and does not return, it was likely a temporary issue and the boiler may continue to operate normally.
However, if the fault code returns repeatedly after resetting, it usually indicates that an underlying issue still exists within the system. Repeatedly resetting the boiler will not resolve gas, mechanical, or electrical faults and the problem may require professional inspection.
Flame Loss
The boiler detected a flame failure during operation.
If this fault repeats, professional inspection is required.
Low Water Pressure
System pressure is too low.
If pressure repeatedly drops, further investigation is needed.
Flame Loss / Ignition Problem
The boiler has failed to maintain a flame.
You may attempt one reset.
If the fault returns, diagnosis is required.
Ignition Lockout
The gas valve is not functioning correctly.
Air Pressure / Fan Fault
The boiler is detecting an airflow problem.
Airflow faults relate to combustion safety and should not be ignored.
Ignition Failure
The boiler attempted ignition but failed.
If L2 keeps returning, internal inspection is required.
Contact a Gas Safe registered engineer if:
Gas and combustion-related issues should always be professionally assessed.
To reduce the likelihood of breakdown:
Preventative maintenance improves reliability.
They are similar but may vary slightly by model.
Low pressure itself is not dangerous, but the cause may require repair.
The ignition issue has not been resolved.
Yes, but repeated pressure loss indicates a deeper problem.
Yes. We diagnose and repair common Ideal boiler faults.
