What is boiler lockout and how do I fix it?
A boiler lockout is a safety feature designed to protect both the appliance and its users by preventing the boiler from operating under unsafe conditions. When a fault occurs, such as low water pressure or ignition failure, the boiler automatically enters lockout mode, effectively disabling itself until the issue is resolved.
There are several indicators that your boiler is in lockout mode...
...as explained by our Director of External Affairs, Martyn Bridges:
"Most boilers will have either some indication on the fascia panel that the boiler has gone to lockout or needs resetting. Generally, these will be a flashing light, sometimes a letter and a number on a neon display or even a written notification if the boiler has a text display. All boilers will differ so you would be advised to consult the user manual that comes with the boiler or go to the manufacturer’s website to access one. All manufacturers also have very useful and competent technical helplines where you can speak to an advisor who will talk you through what’s wrong."
