Most Common Problems When Boiler Not Working

Your boiler plays a critical role in the comfort and functioning of your home or business. Being without a boiler can mean no heating which isn’t good in the winter and no hot water which will be difficult in the winter and summer months. Your boiler not working as it should and operating not efficiently will mean your home or business isn’t a comfortable environment as well as your energy bills increasing more than they need to.

This is why it is important that it is well maintained at all times and serviced when it needs to be. Like other home and business appliances, boilers can experience functional issues, especially as they get older or when they haven’t been serviced. Here are some of the most common boiler issues and what you should do if you experience them.

Pilot Light Going Out – Boiler Not Working

The small gas burner that is always burning on your gas boiler is what is referred to as the pilot light. This can sometimes go out, and often indicates there is an issue with your boiler. It could be the result of gas build-up in the nozzle or even a draught finding its way into the boiler systems pipeworks and blowing out the flame. In some cases, the thermocouple, which monitors changes in the temperature of your pilot light may be broken and cut out the gas supply to the pilot light.

To address this problem, you should check out other boiler appliances on your property to see if they are working or not as this will tell you if you have a problem with your boiler or gas supply. If your other gas appliances are working, try reigniting the pilot light using the instructions in your manufacturer’s manual. If this doesn’t work, you should call a boiler engineer to come out and diagnose the problem for you. Boilers can be dangerous if you don’t know what you’re doing and you should always use a qualified and certified Gas Safe registered engineer for any repairs. The pilot light going out is a lot more common with older boiler models as the latest ones ignite electrically.

Noisy Boiler

Sometimes, your boiler can start making unusual noises that are not only a nuisance to your household but are most often highlighting you have an issue with it. Boiler noises can range from banging and whistling to buzzing and gurgling. If this is happening then chances are there is a problem with the air supply in your boiler system. Noises can also happen as a result of a failing pump or reduced water pressure, depending on the nature of the sound you’re hearing.

Again, check your manufacturer’s guidelines which may give you some idea why it is making a noise. You can try adjusting the boiler settings, however, a noisy boiler can indicate a more serious fault that may not be immediately apparent. If you leave the issue then it can sometimes lead to further more costly repairs so always call your Gas Safe registered engineer who will come out and find out what the problem is for you. If the noises are coming from your radiators and pipe system then you can also try bleeding the radiators or examining the pipework to try and identify the problem.
