Boiler Breakdown Faults London

Most people don’t even think about their boiler until it starts having problems and unfortunately, the most common problem ends up being total breakdown. When it comes to the reasons that cause boiler problems, it could be anything from a broken seal on the boiler pump, a crack in one of aluminum or cast iron sections and more. To give you a general idea of the most common problems to look for, we’ve listed a few below. Before you read on keep in mind that you should never try to alter or dismantle your boiler yourself.

1. One of the most commonly overlooked things to check out if your boiler quits working is to see if the power supply is on. If it isn’t, you’ll need to call your electricity supplier.

2. Check to see if the gas supply is on? If no gas is coming through, but the gas stopcock is on, you have a gas supply problem and will need to call your gas supplier. If it’s an oil boiler, read the gauge to make sure there’s enough oil in the tank.

3. If the pilot light isn’t igniting you might be able to relight it by following the instructions provided by the manufacturer which are usually located either near the pilot light, on the front panel of in a separate instruction booklet that came with your boiler. If your boiler model doesn’t have a pilot light, press the de-blocking button. If that doesn’t work, check the central heating pressure is set to the manufacturer’s instructions (typically one bar). If that also doesn’t work (and the central heating pressure is correct), you either have a gas supply problem (contact your gas supplier) or you’ll need to get an gas safe registered engineer.

4. Make sure that the central heating programmer is in the on position. If it is, try increasing the thermostat level of your central heating/boiler and keep in mind that boilers only works when the thermostat is set higher than the actual room temperature. Also, make sure that the central heating’s timer controls are working and set correctly. If it doesn’t switch, the problem could be something as simple as batteries or an issue with its power source.

5. Another thing to check in relation to the central heating is the pressure; you can turn to the manufacturer’s instructions for troubleshooting purposes. If the pressure isn’t what it should be you may have a gas supply problem and will need to contact a gas safe register professional or your gas supplier.

6. Check the condensate pipe which carries the condensation from the boiler to an outside drain. During extremely frigid weather conditions, condensation in the pipe often freezes, causing a blockage that pushes it back into the boiler and ultimately shuts it down. Signs that the condensate pipe has frozen include a bubbling sound coming from the boiler or pipe as well as the boiler display showing a warning light or fault code.

7. In many cases, the only problem with a boiler ends up being age; if your boiler is over 10 years old, it may be time for a new one. That could actually be a good thing because today’s boilers are a lot more efficient and reliable and can save you quite a bit on your gas bills.
