The Curious Case of the Non-Igniting Boiler: Troubleshooting Tips

Coming home to a cold house in the middle of the winter or being greeted with an unwelcome chilled shower first thing in the morning (talk about a rude awakening!) can be quite a fizzer. They are the unforeseen gifts that quite possibly point to your boiler not igniting! Fear not, we got you covered. Before you reach out to call the emergency repairman and face a hefty bill, here are few handpicked, DIY troubleshooting tips and suggestions to help you reignite the harmony in your home.

Lockout Mode

Your boiler possesses an impressive intuitive processing system that ensures your safety. If the boiler system notes multiple failed attempts at ignition, it enters the “lockout mode”. Much like your frequently forgotten smartphone passcode.

Hey if you were repeatedly failing, wouldn't you want to take a timeout too?

Lockout mode is denoted by a flashing red or constant light on your boiler. To resolve this, you’ll need to reset your boiler. The reset button is typically located on the burner or the control panel. Keep an eye on your boiler’s manual for accurate information on this.

The Plot Thickens: No Gas Supply

The leading lady in the drama of an unignited boiler is often the gas supply. Before jumping into conclusions, check if other gas appliances are functioning well in your household. If they do, the gas supply might not be the issue. Still unsure? You can also inspect the gas stopcock. It could be closed or partially closed. Adjusting it into the open position might be the key you need!

It's All About Pressure

Too high or too low, this isn't your average cup of joe, but your boiler's water pressure. A typical boiler operates efficiently between 1 -1.5 bar. Lower than 1 suggests that it's time to repressurise your boiler. Remember to check your manual or follow online DIY instructions to guide you through this.

Saying No to Blockages

And now for the outsider, the unnoticed yet crucial, the flue! Blocked flues can lead to ignition failure. The blockage may be due to dust, debris or even a mischievous nesting bird! Installing a bird guard can prevent such occurrences, and generally, a dust-off can clear day-to-day obstacles which hamper the flue functioning.

Playing it Cool with the Thermostats

And then we have the thermostat, our little temperature regulator. Having this set too low could mean your boiler won’t ignite because it doesn’t need to! A simple upward adjustment might just light up your day (and your boiler!)

Up Close and Personal with the PCB

Lastly, the printed circuit board (PCB), the brain of your boiler, can sometimes fail. Now this one is a bit tricky. If all else fails, and you suspect a faulty PCB, you might need to reach out to a professional to replace it. Poking your nose into the PCB can be risky if you are not savvy about it.

Remember:

Troubleshooting a boiler is all about understanding each of the characters and carefully considering their roles. Not all heroes wear capes; some come with a toolbox and a can-do spirit! So, take your time, have a pot of coffee and venture into a little DIY troubleshooting before you reach out for that phone.

Parting Nudge

While these troubleshooting tips are helpful and can save you time and money, there are moments when it's best to call for professional help, especially if initial troubleshooting doesn't strike up a spark or if fundamental parts like the PCB are playing up. Let’s heat things up responsibly, shall we?
