Your central heating system and a boiler are the two sides of the same coin. One is completely useless without the other. While modern boilers are extremely reliable, at times you might have to reset the entire system for better performance.. Your boiler might stop working at times due to certain internal issue that keeps it from working efficiently and safely. In such cases, it’s handy to know how to restart the whole system so that you can continue heating your home and get your hot water supply working. 

But how do you reset your boiler?

Discussed below is the A-Z of resetting your boiler so that when the need arises, you’ll know exactly what to do. 

How Will I Know that My Boiler Needs to be Reset?

Because modern boilers are designed with a safety feature, they tend to stop working in case they detect any internal fault. This shutting down of the boiler is known as ‘boiler lockout’ and the reason for this could be any number of issues. Primary reasons for boiler lockdown is due to pressure being either too high or too low. Boiler lockdowns can also happen due to ignition failure caused by an interruption in fuel supply or if the burner or the heat exchanger is blocked. 

Whatever the reason, you’ll be able to determine the reason behind the lockdown as your boiler will display an error code matching the issue. If you’re unsure as to what the error code means, you can take a look at the manual provided by the manufacturer. 

Why Should I Reset My Boiler?

Before you go ahead and hit reset, it’s important that you address the issue that caused a lockdown in the first place. If you fail to do this, you’ll find that you have to constantly keep resetting the heating system, further increasing the chances of serious damage to the boiler. 

If your boiler keeps shutting down even after you’ve fixed the issue, it’s probably because it has an ongoing flaw. The reason for this could be:

  • A broken pump
  • Leakage somewhere in the system
  • Electrical fault
  • Blocked heat exchanger

In such cases, calling in a Gas Safe Registered engineer as soon as possible is recommended. Depending on the reason for constant boiler lockdown, it might be time to replace your existing system. Frequently getting outdated and unreliable boiler fixed will prove to be an expensive affair. You’ll be better off investing in a new model instead!

Resetting a Boiler – Step-by-Step Instructions

  1. Identify and Fix the Issue – As mentioned above, check the manual for the corresponding error code and get to the root of the issue. If you’re still unsure, contact a qualified engineer to fix your boiler.
  2. Find the Button and Hit Reset – Modern boilers have the reset button situated on the display of the boiler itself. This will be in close proximity to where the error code is shown. In case you can’t seem to find the reset button, consult the boiler manual. 
  3. Press and hold the Reset Button – After you find the reset button, press and hold it for 3 to 10 seconds. 
  4. Wait for the Boiler to Restart – After being reset, most modern boilers go through a series of internal resetting functions and only then will they start working again. This means that most boilers will not start working immediately after being reset. This could take up to 5-10 minutes.

And that’s it! Your boiler has been successfully reset!

When you know how to reset your boiler, you can ensure that you have continuous access to hot water and heating as per your requirements. However, even after following all the necessary steps if your boiler keeps shutting down or won’t reset, its high time to get in touch with a heating engineer.
