Resetting the Boiler


Understanding the Issue

Sometimes boilers lock out due to safety issues or minor faults, showing an error code or flashing light. A simple reset can restore normal function—similar to restarting a computer.



When You Might Need a Reset

  • No heating or hot water
  • Display shows a fault code
  • Red or flashing warning light




What You Can Do


Most boilers have a reset button or dial function.



Typical Steps (Baxi Example):

  1. Press and hold the reset button for a few seconds
  2. Wait while the boiler restarts
  3. Check for continued error messages

Please refer to your boiler manual if the model is different.



Safety Reminder

If your boiler resets repeatedly or shows unusual behaviour (e.g. leaking, loud bangs), do not attempt further resets. Call us for support.



When to Report It

  • The boiler doesn’t respond to a reset
  • The issue keeps recurring
  • There are any safety concern
