Diagnosing Your Boiler Issues: A Guide To The 10 Most Frequent Causes Of Failure

Your boiler is one of the essential appliances in your home. It is responsible for keeping your house warm and providing hot water for your daily needs. But when it stops working correctly, it can be a considerable inconvenience. In this post, we will discuss the 10 most common causes of boiler failure and how you can troubleshoot them.

1. No heat or hot water

This is the most common problem that homeowners face with their boilers. If your boiler is not producing heat or hot water, it may be due to a faulty thermostat, low water pressure, or a broken diaphragm.

2. Strange noises

If you hear strange noises from your boiler, such as banging, whistling, or gurgling, it may be due to air in the system, a faulty pump, or a broken heat exchanger.

3. Leaking

Leaking boilers can cause damage to your property and are a safety hazard. If you notice any water leaking from your boiler, it may be due to a faulty valve, a damaged pump seal, or a cracked heat exchanger.

4. The pilot light goes out

If your boiler’s pilot light keeps going out, it may be due to a faulty thermocouple or a blocked pilot jet.

5. Low pressure

Low boiler pressure can cause your heating system to stop working altogether. It may be due to a water leak, a faulty pressure relief valve, or a faulty expansion vessel.

6. Radiators not heating up

If your radiators are not heating up properly, it may be due to air in the system, a faulty radiator valve, or a blocked pipe.

7. The boiler turns off by itself

If your boiler keeps turning off by itself, it may be due to a faulty thermostat, a blocked flue, or a broken pump.

8. Kettling

Kettling is a term used to describe a boiler that makes a rumbling or banging noise when it is on. It may be due to a limescale buildup, a faulty thermostat, or a blocked pipe.

9. Frozen condensate pipe

If your condensate pipe is frozen, your boiler will stop working. This is a common problem during cold weather and can be prevented by insulating the pipe or using a frost protection device.

10. The boiler won’t turn on

If your boiler doesn’t turn on, it may be due to a faulty thermostat, a blown fuse, or a broken pump.
