Most Common Boiler Issues


Leaks can be detected by looking at the boiler pressure indicator. If it continues to drop even after you’ve topped up your machine, then chances are it is caused by a leak somewhere around the system.

Finding the leak will mean following your pipework and inspecting everything carefully, from the boiler to all the connected points throughout your home. If this is not an activity you have the time and energy for, then call a qualified professional in to do it for you instead.

No Pilot Light

The pilot light is the flame that ignites the gas in gas boilers. If it does not turn on, then this reaction cannot happen and your boiler cannot get to work. New boiler models rarely include an actual pilot light, so you may be dealing with more sophisticated kinds of technology for ignition. If restarting the system does not work, have an engineer look at the issue and solve the problem for you.

Scheduling Timer Problems

This problem usually occurs in electronic boilers. If your equipment is not firing up at the scheduled time, then it could be caused by something as small as the clocks changing or the options being configured incorrectly. Refer to the manual for more information and try looking through all the settings before you call someone in to have a look.

Fuel and Electricity Issues

Boilers can be fueled by gas, wood, or electricity. But if it is not functioning properly even with a strong source of fuel running, then you may be suffering from a faulty connection in the system somewhere. Unfortunately, dismantling and reassembling an entire boiler system is a complex assessment that should only be done by an experienced professional. If you try doing it yourself, you put your safety at risk and your boiler warranty may be voided.

Can I Repair My Own Boiler?

If your boiler is less than three years old and in good condition otherwise, then maybe the answer to your problems can be found in the manual or online. In this scenario, you can take it upon yourself to investigate, diagnose, and implement a solution.

But if you need to disassemble anything or work closely with fuel sources, then you need to get an engineer to do it for you. Do not compromise your safety.

Is It Better to Repair or Replace a Boiler?

In many cases, repairing a boiler is better than replacing it. Being proactive about problems will help you nip them early in the bud, but even the most careful homeowners run into issues after a while. There are plenty of issues that are outside of our control.

Consider replacing your boiler if it is more than twenty years old, has started breaking down frequently, or if you believe that its’s started leaking gas and leaving your household at risk of carbon monoxide poisoning.

Can a Crack in Boiler Be Repaired?

If you have a crack somewhere on your boiler, the fix isn’t just as easy as finding the place of origin and slapping some tape over it. This will call for the work of sealant, which is available in either liquid or powder form. You may need to prepare the powder by mixing it with water beforehand.

First, locate the crack and then find an opening to the system somewhere near it or go for the safety valve instead, if no openings exist. Next, fill the boiler with water until levels reach ½” above the crack. Pour the sealant inside and apply pressure to the boiler until it reaches maximum allowance. Maintain this setting for the allotted time that the sealant needs to work. Depending on the brand of sealant and the size of the crack, this may take anywhere between thirty minutes to two hours.

Some cracks may be too big to repair. In that case, you may want to consider having your boiler system replaced instead. This will take plenty of time and effort, and it’s going to be a massive activity, so consult an expert on this matter before jumping into any conclusions.
