When your boiler suddenly stops working, it is often due to a simple issue that can be resolved with a reset. Error codes, low pressure, or minor interruptions in power can cause a boiler to enter lockout mode, a built-in safety feature that halts operation. In many cases, a straightforward reset is all that is needed to get your heating and hot water running again.
This guide will walk you through the boiler reset process step by step. Whether you have a gas or electric system, you will learn how to locate the reset button, manage power or gas supply safely, and monitor your boiler after restarting. If the problem persists, we also explain when it is time to stop troubleshooting and call a professional in Northumberland & Newcastle
Step-by-Step Instructions for a Safe Boiler Reset
Step 1: Locate the Reset Button
The reset button is usually found on the front of the boiler or inside the control panel. It is often red and clearly marked. If you are unsure, consult your boiler’s user manual for guidance.
Step 2: Turn Off the Power or Gas Supply
To ensure safety, switch off your boiler before resetting.
For electric boilers:
- Go to your main electrical panel
- Find the breaker labelled for the boiler
- Turn it off
For gas boilers:
- Locate the gas supply valve
- Turn the valve to the off position (usually perpendicular to the pipe)
Step 3: Press and Hold the Reset Button
Once the boiler is fully powered down:
- Press the reset button firmly
- Hold it for around 10 seconds
- Release it and wait for a response
You might hear the boiler restart or see lights come on — this typically means the reset has been successful.
Step 4: Restore Power and Monitor the Boiler
After completing the reset:
- Switch the power or gas supply back on
- Observe the boiler for a few minutes
- Check for any new error codes or warning lights
- Use the boiler’s app, if available, to confirm its status
Monitoring ensures the issue has been resolved and the system is functioning properly.
Step 5: Try Again or Call a Professional
If an error persists:
- Switch the boiler off again
- Wait for 10 minutes
- Repeat the reset process once more
If problems continue after another attempt, it is time to contact a qualified heating engineer. Persistent issues can indicate underlying faults that require professional attention. If you are based in Northumberland or Newcastle, our team is ready to help.
