If you find that you keep having to reset your boiler, it’s likely that there could be a fault with your heating system. This fault could eventually lead to a more serious issue such as a boiler breakdown, so it’s best to seek out a solution as soon as possible.
How can I tell that my boiler needs resetting?
Usually, when modern boilers need resetting they will display a fault code or begin to flash a red or green light. These signals indicate that your boiler senses a problem, which is why it has stopped working and needs to be reset.
Common underlying causes include:
- A leak in the heating system
- A pump fault
- A faulty electric part
- A blocked plate heat exchanger
- An old or worn out component
- Low pressure
- Insufficient air intake from the flue
- Boiler ignition problems
What is a boiler lockout?
A boiler lockout happens when your boiler shuts down due to an issue within the system. Resetting your boiler is usually the first solution for a lockout. However, you must bear in mind that this will not solve the underlying issue with the boiler, you will need assistance from a qualified engineer.
How do I reset my boiler?
The way in which you reset a boiler may vary depending on different boiler brands and models. For instance, the way in which you conduct a Worcester Bosch boiler reset may differ to the process for resetting a Vaillant boiler. You should refer to your user instructions for exact guidance.
Typically, to reset your boiler you should conduct the following steps:
- Locate the reset button on your boiler – Look for a button that has a flame, flashing light, or a cross written through it. This button should clearly be labelled “RESET.” Refer to your boiler’s instruction manual if you have trouble finding the reset button – this should include a detailed diagram of your specific model.
- Only press the reset button once – You may damage the control panel if you repeatedly press the button – which could lead to an expensive repair.
- Hold the reset button for 3 seconds before releasing – You should be able to tell if your boiler has been reset properly as it will usually display a flashing green light. If a fault code is still showing or the red light continues to flash, we recommend that you contact a Gas Safe registered engineer for assistance as there may be another problem.
