Checks to carry out when your boiler breaks down

1. Electricity Supply

Tripped Fuse Box

To begin, check to see whether a switch in your fuse box has tripped, since this might affect your boiler, especially during a power outage causing the timer to reset. We recommend checking the time shown on the clock and to reprogram it if it does not match.

Meter

If you have a prepaid meter, there may be a chance that it has run out of credit, causing your electric supply to be cut off and stop your boiler from working. 

2. Gas Supply

Gas Valve

When there is something obstructing the gas flow, the boiler fails to ignite. Try checking your other gas appliances to ensure they are still working and ensure that the Emergency Control Valve hasn't been turned off, this can easily be found next to the gas meter. We recommend hiring a Gas Safe registered engineer to inspect your gas supply. 

Gas Pressure

Your boiler may have issues if there is too much or too little gas. If the gas pressure is incorrect, your boiler will most likely show a fault code. Get a trained and qualified engineer to test the gas pressure in your central heating system.

3. Are the pipes frozen?

Because of the UK's severe temperatures in the winter, it's very common for the weather to damage your piping system, and frozen condensation may quickly produce a blockage. This obstruction might cause the boiler to overflow and cause it to shut down. So if your boiler has broken down, check to see if the pipes are frozen, helping you understand the cause of your boiler issue!

4. Fault Codes

You may have noticed a fault code on your boiler which can either help you understand whether the issue you are presented with can be fixed on its own or requires professional help. You should be able to find your boiler handbook online if you don't have it. It will include instructions that will walk you through the most frequent boiler error codes and how to fix them.

5. Pilot Light

On older boilers, a pilot light going out for a variety of causes is very common. To start, you may try to light the pilot light on your own by following the directions in your boiler handbook. Our heating engineers highly suggest not to disassemble or modify your boiler on your own. If you are unable to relight the pilot light, please contact a Gas Safe Registered engineer.

6. Thermostat & Programmer

Your thermostat should be adjusted above room temperature and your programmer should be turned on. If your central heating system is controlled by a timer, the clock may have moved ahead or backwards and has to be corrected.
