BoilerFaultCodesYour boiler has shut down because a sensor has detected that the exhaust gases are getting too hot, which is a safety feature to prevent damage.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Flue thermostat sensor tripped (lockout)
What causes this fault?
This fault occurs when the internal temperature of the boiler rises significantly above safe limits, specifically within the exhaust system. The most common reasons include a blockage in the heat exchanger that prevents heat from transferring to the water, or a pump failure that stops water from circulating correctly to cool the system down.
