Troubleshooting Your Boiler

Boiler servicing and boiler repairs can be very expensive, sometimes costing thousands.

Of course, this all depends on the company or independent plumber you hire, but why pay out such a large sum if the problem is minor.

Before reading on, remember it is illegal to tamper with a gas boiler. You cannot remove or repair the boiler unless you’re a registered, qualified engineer.

If you smell gas, then this could be an emergency. Avoid using any electrical appliances and open all your home’s windows for increased ventilation.

Call the Gas Emergency Line on 0800 111 999.

Boiler Power supply

It’s pretty easy to check this, simply try turning on another of your electrical appliances. If these work, ensure your boiler is plugged in and turned on.

However, if your home is not receiving electricity, call your energy supplier immediately.

Boiler Gas supply

Just like checking the power supply, this is quick and easy. Something like the cooker or hob can be checked for gas, and if none is coming through ask your neighbour if they too have a problem.

If the stopcock is on, but your home is not being supplied with gas, then you should contact the supplier.

For other gas related problems, you can contact the gas safe register at www.gassaferegister.co.uk

Boiler Thermostat and programmer

There’s not much to do here. Just check that the thermostat is above room temperature and the central heating boiler programmer is on.

Boiler Pressure

Once again, a pretty straight forward procedure. Ensure the boiler pressure is set to the manufacturer’s recommendations (as found in the manual).

This information can also be found on the internet and is usually between 1.0 and 1.5 bar.

If you find that your boiler’s pressure is not correct, use the instructions to refill and restart the system. However, if it’s correct, there may be a gas problem (See above).

Boiler Pilot light

If the boiler’s pilot light goes out, it doesn’t mean that an engineer is needed to fix the problem. Instead you can relight the pilot, using the instructions on the inside of the door or in the manual.

However, if for whatever reason it won’t light, then it’s probably a gas problem.
