How do you know your boiler has a fault?

Listed below are common Fault codes displayed on a boiler system;

boiling

Code F27: This shows a condensate pipe is likely frozen.

Code F22: This indicates a commonplace boiler fault – low water pressure.

Code F75: This indicates your boilerís sensor is not aware the pump has started running. Itís a common problem seen in older boilers that have had magnetic filters fitted or that havenít been flushed in a while.

Code F28: This is caused by no gas getting to the boiler, or a faulty ignition.

Code F29: This points out the boiler flame is not on.

Odd noises coming from your boiler

Boiler emitting strange noises – Air getting in your boiler system is the usual cause.

Issues with thermostat

Issues with thermostat – it’s advisable to get a new thermostat when your boiler’s thermostat begins flipping your heating on and off or displays inaccurate readings.

Boiler keeps turning off

Boiler keeps turning off – Usual culprits are a lack of water flow due to a closed valve, low water pressure, and air in the system or a problem with the thermostat or pump which are not circulating water in the system properly.

Radiator not getting hot

Radiator not hot enough – Radiator not getting hot enough or only its bottom section heating up can be caused by an accumulation of sludge or air in the system, or an uneven distribution of heat.

No heat or hot water

No heating or hot water – Tends to be as a result of a broken airlock or diaphragm, a broken motorised valve, low water level or a damaged thermostat.

Boiler leakages

Leaking boiler – A leaking gas boiler is safer switched off, and looked at by a Gas Safe registered engineer. Never attempt fixing your leaking boiler on your own unless you have the required training.

Blown out pilot light

Blown out pilot light – A damaged thermocouple might be stopping the gas supply, or you might not be getting any gas supply into your house. A blown out pilot light or accumulated dirt in the pilot light compartment are also possible causes.

Falling pressure

Falling pressure – If your pressure gauge indicates “below 1”, the issue might be caused by either a water leak in the system or the pressure relief valve needing replacing or that the radiators were recently bled.
