Halstead Boiler Fault Codes

Your boiler has tried to light the flame five times but failed, so it has safely shut itself down to prevent a build-up of unburnt gas.

Your boiler has detected that it has become too hot and has automatically switched itself off to prevent any damage.

Your boiler is failing to ignite or stay lit because it cannot detect a flame, meaning you currently have no heating or hot water.

Your boiler is struggling to detect that the internal fan is venting air properly, which prevents it from igniting safely.

Your boiler has automatically shut down because it has detected that its internal water temperature has become dangerously high.
