BoilerFaultCodesYour boiler is working but it isn't heating the water to the usual temperature, which might make your home feel less warm than normal.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Boiler operating at lower flow temperature
What causes this fault?
This fault occurs when the boiler's internal sensors detect that the water is not reaching the required heat level, often due to a degrading component sending incorrect signals. The most common reason is a faulty temperature sensor or a worn control knob that can no longer accurately communicate your desired heat setting to the main computer.
This issue is often more noticeable during the winter months when the lower flow temperature struggles to overcome the cold outdoor conditions to keep your home warm.
DIY fix possible
Check that the thermostat on the front of the boiler is not turned down too lowCheck your room thermostat is set to your desired temperatureMonitor the boiler for several hours to see if the temperature increases naturally
