Boiler Stopped Working? Follow Our Top Tips to Fix It:

Check your mains gas supply.

You can do this by checking your other gas appliances such as your gas cooker or gas fire. If these are working as usual, your mains gas supply is most likely fine and the problem is with your gas boiler. If the mains gas supply isn’t working, then give your gas supplier a call for advice on the issue. If you are on a meter, check that you have enough credit on your prepayment card.

Check your thermostat.

Sounds obvious, but if the temperature is set below 21 degrees, the boiler won’t always come on. Simply try turning the temperature up to see if it kicks the boiler into life.

Check the pressure gauge on your boiler.

A noisy boiler can sometimes be a sign of low water pressure in the system. If you have a combi boiler or a sealed system, you can let more water into the system by releasing the pressure valve (normally found at the front and underneath the boiler). The pressure gauge should show between 1 and 1.5 bars when the system is turned off. If it’s below this, there won’t be enough pressure in your system and it will fail to operate. Refer to your boiler instruction manual if you need help on repressuring a boiler.

If you have an open vented central heating system, you should check that there is enough water in the system by checking the water level in any loft tank. You should also check there’s no sludge or debris inside the tank as this can get into the pipes and clog up the system.

Check that the pilot light is on.

If you have an older boiler, chances are you’ll have a model with an accessible pilot light. Check that the pilot light is on and that the flame is burning blue. If the light has gone out, you can try and ignite it by following these steps.

Check that there’s no dirt or debris blocking up the system.

Boiler and pipes noisy? Radiators warm at the top but cold at the bottom? This can be a sign of a rust and sludge build up in the system, which will prevent it from heating up efficiently. This usually requires a system power flush to be carried out by a professional.

Check for error codes.

If you have a contemporary model boiler installed, it will most likely show an error code on the digital display if there is a problem. Refer to your manufacturer’s handbook for an explanation of the error code. If it’s not something you can fix yourself, then it’s time to call in an RGII qualified gas engineer.
