What to Do When Your Boiler Locks Out
A boiler lockout is a safety feature that shuts down the boiler when it detects a fault condition. This guide helps you safely reset your boiler and determine when professional service is needed.
Immediate Steps to Take
1. Check the boiler display panel for an error code — write down the code before pressing any buttons. 2. Press the boiler reset button once — most boilers have a dedicated reset button (often red) on the control panel. Hold for 1-3 seconds as needed. 3. If the boiler fires up and operates normally after a single reset, monitor it for the next hour for signs of recurring issues. 4. If the boiler locks out again immediately after the reset, do not keep resetting — repeated resetting can damage components and accumulate unburned gas.
Next Steps
5. Check the boiler pressure gauge — if pressure is below 1 bar, the boiler may be locking out due to low pressure. Repressurize using the filling loop. 6. Check that the gas supply valve is fully open and that other gas appliances in your home are working. 7. Call for professional service if the boiler locks out repeatedly, displays an error code you cannot resolve, or if you suspect any gas-related issues.
