We hardly notice our boilers working hard to keep our homes heated. That is until you step into a cold house or have the shock of an ice-cold shower!

 

At Green Flame we have put together this helpful guide to teach you the tell-tale signs of common boiler issues. Plus, learn how to fix them.

 

While we always advice you have a professional take care of your boiler repairs and servicing, it’s useful to know the quick fixes that can resolve minor issues.

What’s wrong with my boiler?

 

Are you experiencing:

  • The boiler switching itself off
  • Central heating is making loud banging sounds
  • The radiators furthest away from the boiler have stopped heating
The problem = Low Pressure

 

How to fix it:

If the pressure gauge on your boiler control panel reads less than 1 bar, carefully use your valve to increase it to between 1 and 1.5. You may have to reset your boiler once you have done this. Check the manufacturers guide for more information. For Worcester Bosch boilers click here.

If you are still experiencing a loss of pressure after this, you may have a pipe leak. Call one of our engineers on 01452 412 549.

 

Top Tip!
Your boilers brand website often contains helpful tutorials and videos about how to deal with common issues like low pressure.

 

Are you experiencing:

  • Boiler making a gurgling sound when you use it
  • It won’t fire up
  • The outside temperatures have been particularly low recently

 

The problem = A frozen condensation pipe

 

How to fix it:

Cold weather can be a nightmare for boilers. You can thaw this yourself by applying hot (not boiling) water along with a warm compress onto the pipe.

 

 

Are you experiencing:

  • The boiler isn’t turning on when it should, or comes on at random times
  • It won’t fire up
  • Your thermostat shows an error message or is blank
    The problem = Issue with the settings of your boiler or thermostat

     

    How to fix it:

    A power cut can cause problems with the settings, or sometimes the panel has been interfered with by accident. Double check this isn’t the case. Check the settings have the temperature set about 21 ℃ as this can sometimes stop the boiler from firing up.

     

    Top Tip!
    If your thermostat is battery powered, consider changing these. These should be changed every 8-12 months approximately.

     

    Are you experiencing:

    • No visible pilot light
    • The boiler won’t fire up

     

    The problem = The pilot light has gone out

     

    How to fix it:

    This is usually a straightforward fix. Instructions on how to re-light the pilot light can be found on your boiler. However, if you smell gas or notice a change in the flame colour do not try to reignite it. Call the emergency gas line on 0800 111 999.

     

    Are you experiencing:

    • The lock-out (red) light on the boiler keeps coming on
    • The control panel on the boiler shows an error code
    • It won’t fire up

     

    The problem = The boiler locks out and needs resetting

     

    How to fix it:

    This often requires just a simple reset. The reset button is usually located on the front control panel of your boiler. If you cannot locate it, check what it says in your boiler’s instruction manual. If you are still having problems, try switching it on and off again.

     

    If any of the problems listed above continue to occur, then call one of our engineers who will be more than happy to help rectify the issue.
