How to Reset a Boiler: A Step-by-Step Guide for Tunbridge Wells, Crowborough & Nearby Areas
Boilers are the unsung heroes of the home — especially during the colder months across Tunbridge Wells, Crowborough, Uckfield, Rotherfield, and Mark Cross. When your heating stops working, a simple boiler reset is sometimes all it takes to get things running again.
Whether you’ve had a power cut, an error code, or your boiler simply isn't firing up, knowing how to safely reset your boiler can save time and help restore hot water and heating fast.
In this guide, Absolute Plumbing & Heating walks you through how to reset most common boiler brands found in homes throughout West Kent and East Sussex.

Why Resetting Your Boiler Matters
When your boiler displays a fault or stops responding, it may go into lockout mode. This is a safety feature designed to protect your system. Resetting tells the boiler to clear the fault code and try again.
In towns like Uckfield and Mark Cross, where older systems are still common, boiler resets are a regular callout we attend.

⚠️ Safety First
Resetting a boiler via the controls is safe for homeowners to do. You're not opening the casing or working on gas components. But if the problem persists after a reset — don’t keep trying. It could indicate a deeper issue, and it’s time to call a Gas Safe registered engineer.

Signs Your Boiler Might Need Resetting
Here are common situations we see in Crowborough and Tunbridge Wells homes that often lead to a successful reset:
No heating or hot water: especially after a power cut
Error or fault codes on the boiler display
Thermostat issues or communication loss
Flashing lights (particularly with Worcester Bosch boilers)
If these symptoms persist after a reset, contact Absolute Plumbing & Heating to investigate.
