Main Boiler Problems and Common Fault Codes

Main boilers come with an on-board diagnostics mechanism that makes it easier to diagnose and fix any problems the boiler has. Some of the problems are easy to fix and you might not even need the help of an engineer to sort them out.

Others are more complicated and require expert intervention to be handled safely. Regardless of the nature of the issue with your Main boiler, knowing some of the common fault codes and problems is essential. It can help you avert potential danger or avoid the inconvenience of waiting for a boiler engineer when you could have resolved the issue yourself.

Here are some of the common Main boiler problems and error codes:

Faulty components

Main boilers display different error codes for defective parts depending on the component. Some of the error codes you might come across on the display panel associated with a faulty component include E20, E28, E50, and E160.

Suggested fix

There’s not much you can do in this case other than calling your installer. They can decipher which component is having issues and what needs to be done. By sharing the error code, you can help the install determine the parts he needs to carry to get your boiler working again.

Error code 110

If the boiler is showing this error code, it means the water is overheating, or the flue system is failing. There are various causes for this problem one of them being a failing component. If it’s the first time the boiler is showing this code, it might be possible to iron things out before you call in an expert.

Suggested fix

You can turn the selector switch to the reset position and hold for about five seconds to restart the boiler. Should the boiler fail to relight or keep displaying the code, you need to contact your installer. There could be a blockage in the boiler that is preventing the circulation of the water or a failed valve.

Error 119

This error is usually displayed when the boiler pressure is less than 0.5bar. If the boiler pressure is low, the boiler will cut out and switch off to prevent further damage. A quick look at the pressure gauge on the boiler will confirm the problem.

As much as this sounds like a big problem, it’s something you can actually solve very easily by repressurising the boiler.

Suggested fix

You need to locate the filling loop on your boiler and use it to add water into the system. Adding water increases pressure. Be cautious not to add too much since that would cause another problem. If the pressure drops again, you need to consider having an engineer inspect the boiler for leaks.

If a leak is found, it needs to be fixed quickly to prevent further damage to the boiler and to your home.
