Boiler Won’t Ignite? Why And How To Fix It (Error Codes ADDED)

Boiler

You finally make it into a bath after a hard day’s work, only to realise the water isn’t the temperature it’s supposed to – you know, hot and indulging… Quite painfully, your boiler doesn’t ignite, sabotaging your special time.

Now you might wonder:

  • “Why won’t my boiler ignite?”
  • “How to turn it on?”

No heating and hot water mean a hell of a single or a plethora of boiler and non-boiler-related reasons. Anything from a burner blockage to low gas pressure endangers the safety of your and sky-rockets your bills. Still, if you are lucky enough, a boiler ignition failure could be easy to detect and solve. 

Curious about what those problems might be? 

Here, Boiler Grants share a handful list of common reasons why your boiler won’t ignite.

#1 Boiler Has No Power

For most of us, fuel is all you need to ignite a gas boiler. Wrong! 

Truth is, boilers comprise electrical components. Be it an LCD screen, power-lighting bulb, or thermostat, they all pursue electricity to streamline your hot water and heating systems. 

Expect your boiler not to click when:

  • Power goes out during a storm;
  • You changed thermostat settings to error;
  • You turned the boiler button off by accident;
  • Your fuse box trips because of a power cut.

How to ignite the boiler?

  • In case of a power cut, push the boiler reset button and hold it for 10 seconds. Then, wait a few minutes for the boiler to ignite. In a click, have your manufacturer’s manual for any special instructions, if needed.
  • Change your assumptions for a power outage if home’s appliances are still up and running. Be sure to check the fuse-board switches and flick them back, if they aren’t. Switches UP = Electricity ON. 
  • Reset your timer if power loss restores appliances back to factory settings. You’ll get out of the problem, and your unit will turn on at the preferred times. 
  • Don’t trust old thermostats (>5 years). Misjudged temperature may be the culprit of a boiler ignition problem. Consider installing a new thermostat to help your boiler work again. 

As a bonus: With Boiler Grants, you can get a free boiler installation plus new heating controls, so you can enjoy trouble-free heating and improved efficiency. 

#2 No Gas Supply

If you don’t see obvious damage, unexpected interruption of gas supply may be the cause for the boiler ignition failure. Factors for this can vary. But one you can’t ignore is a frozen gas meter during harsh cold spells. If the weather is not to blame, seek the boiler ignition failure in the domestic gas supply rather than in your boiler. 

How to ignite the boiler?

  • Ensure your gas hob, cooker or dishwasher work at peak performance. Fading flame equals to no gas supply.
  • Keep outstanding payments to a minimum. Access your online account to confirm that your gas bill is paid. 
  • Be wary of yellow/red winter warnings for snow. Act proactively and prevent your gas meter from freezing with adequate lagging.
  • Be on alert if your meter displays “ON”, but gas supply to the boiler is “OFF”. Check your gas supplier website or call the emergency number to ask for help.

#3 Inconsistent Gas Pressure

In the world of heating systems, boiler pressure helps you understand the balance between water and air in your boiler system. For residential boilers, the sweet spot for your indicator needle is 1-1.5 bars. When boiler pressure is too low or too high, there lies a major problem.

The last thing you want is to discover a pressure fault error on your boiler screen. But if your appliance lockout, wade through the following errors: 

Boiler manufacturer Error code
Worcester Bosch  A1, CE 207, H07, 224 V, 1017 W, 2970 B, 2971 B
Ideal F1
Biasi Insufficient pressure
Potterton E119
Glow Worm F.75, Red LED On, F9
Ariston 108
Vaillant F.24, F.72, F.22, F.12, F.74

How to ignite the boiler?

  • Low boiler pressure scenario. To top-up (re-pressurise) your pressure is the best defence against submerging pressure gauge readings. Do a single turn of the filling loop handles and you can resume the air-water balance in a few seconds.
  • Over-pressured boiler scenario. Sometimes, all you have to do is to release air from central heating. Get a radiator bleeding kit and jump on it yourself. Still, subtle leaks and malfunctioning parts can make you sweat and cry. Consider the possibility of calling a heating expert.

#4 Blocked Burner

Boilers heat both water and your home because gas burners do the hard work: generate heat. But with time and use:

  • Gas burner wears out; 
  • Carbon builds up on the heating element.
  • Chances of boilers not to igniting raise.

Finding the cause of burner fault is the first step to diagnosis and fix. So, be sure to check your boiler error codes:

Boiler manufacturer Error code
Worcester Bosch  EA 261, F0 238, F0 239, F0 242, F0 243. F0 244. F0 245, F0 246. F0 247, F0 248, F0 249, F0 250, F0 251, F0 252, F0 253, F0 255, F0 259, F0 263, F0 267, F0 272, F0 280, F0 290,EC 256,  EH 258
Biasi ER 01 + Reset , Burner ignition (spark), Delayed burner ignition
Glow Worm F.83
Vaillant S.4, S.24, S.28, S.20

 

How to ignite your boiler:

Most often, clogged burners occur in boilers lacking proper servicing. 

The rule is, clear out built-up carbon and debris from the burner, at least once per year. That’s how you add life to your appliance and make the combustion process more efficient. 

Be warned: A fault with the gas burner is something only a Gas Safe-registered heating engineer should look into. 

#5 Gas Shut-Off Valve Fault

Like a plug, the boiler valve controls gas flow to the pilot light and burner. How?

  • Open valve = allows fuel to ignite the boiler;
  • Close valve = blocks gas from escaping as the water reaches temperatures set. 

Yet, even the sturdiest gas valve can become: 

  • Seized or stuck;
  • Corroded or blocked by dirt and grime;
  • Have damaged wired connections,

– often due to age. 

Without the correct gas level, you experience costly boiler problems such as lack of flame or flame instability:

Ideal Flame on before gas valve is on;
Replace gas valve;
Check wiring from gas valve to printed circuit board (PCB)

Glow Worm F26 / F77, F15, 306 V
Ariston 501
Vaillant F.26, F.61, F.62, D.30

 

How to ignite the boiler?

“Even the sturdiest gas valves can easily break down. These faults are hard to detect if your boiler doesn’t have an LCD screen” commented Shane Bruce, a heating engineer from the London-based Fantastic Handyman Company. “The remedy could be something as simple as losing a seized valve or replacing the heating component. Before you opt for the second route, consider upgrading your ageing heating system”. 

#6 Frozen Condensate Pipe

When temperatures plummet to sub-zero degrees, boiler condensate pipes are at high risk of freezing. For ignition issues, blame bad condensate pipe installations or the lack of protection. 

More than just an annoying gurgling noise, a frozen condensate pipe can damage joints, cause leaks, excessive pressure, loose piping, and the list goes on… Thankfully, modern boilers have a safety precaution detection mechanism for frozen pipes that shut the system off. 

How to ignite the boiler?

Not all boiler ignition problems are DIY-friendly, but issues with frozen condensate pipes are. Gear up with a bucket of warm water and pour it over the exposed end of the pipe until icing melts.

Thumbs up for those of you who already apply condensate pipe lagging. For less freezing troubles, ask an engineer to re-install the boiler condensate pipe internally. If internal discharge is impossible, correct the pipe slope and reduce the bends to a minimum.

#7 Pilot Light Is Not Lighting (Flame Failure)

If the tiny blue flame that lights the gas is dying, your boiler will let you know. It won’t ignite, alerting you for potential danger. 

Strong draft, debris blocking the jet, stuck gas valve or blockage in the flue – one or more of these might be the reason for a pilot light going out. 

Many might turn out minor repairs. Don’t do everything on your own, though. Call a professional to inspect the faulty component, disassemble it, and give it a deep-clean so your boiler can finally run again.

How to ignite the boiler?

Before making a service call, there are two options to reignite the pilot light back. 

  • Reset the boiler – the procedure will usually do the trick. 
  • Double-check the pressure gauge and top it up if readings are less than 1 bar.

#8 Boiler Fan Is Not Working

Boilers don’t use their in-built fans to cool themselves. (Sigh!) 

Out-of-sight, your boiler fan acts as the sustained, turbulent wind that blows dangerous gases out of the flue. But if the fan is sluggish, or rotates irregularly, wind and fine dust can barge into the flue. 

The result? Expect a blown out pilot light, the least. Fortunately, the PCB recognises these fan control system frictions. Its reaction is ignition fault, reducing the risk of avalanche unsafe conditions.

Be sure to check the likely error codes: 

Boiler manufacturer Error code
Worcester Bosch  C1, C6, C7, T2, C6 215, C7 214, C7 216, C7 217 , C1 264, C4 273, 
Ideal F3
Biasi ER 05 
Potterton E160, E161 
Glow Worm F2
Ariston A41, 604
Vaillant S.1, S.6, F.32, S.11,S.14, S.15, S.16, S.21, S.25, S.26, S.32

How to ignite the boiler?

When dealing with boiler fan faults, DIY enthusiasm is the backwards sort of thinking. Rotation and speed problems, loose or damaged connections, air faults – all these are weird tumbleweed issues. A dexterous heating engineer can untangle issues without causing systems to fail. 

Though you may need it, don’t replace your fan without talking to a heating expert. Parts start from £150 across the UK, but if you feel as one low-income household, why don’t you try reconditioning the unit first? Or, if your fan is running slower than expected, it might need a speed adjustment. 

#9 Ignition Lead Fault

Boiler clicking ON and OFF when heating the hot water? Creepy noises? The most likely cause is a faulty ignition lead or an electrode glitch. 

For boilers, ignition lead is a key accessory. That’s why your appliance won’t ignite if the flash is slow or delayed. 

Now, check the exact reason for the ignition failure on your boiler display: 

Boiler manufacturer Error code
Worcester Bosch  EA, F0,  T1, EA 227, EA 269, Slow flash ( mostly off flashes on)
Ideal L2
Biasi Burner ignition (spark)

Delayed burner ignition for setting the system

Potterton E133
Glow Worm F28 / F1 / F4, Poor burner pressure
Ariston 5P1, 5P2
Vaillant F.28, F.4, F.1, S.3, F.29, S.03, S.04, S.23, S.23, D.68, D.69

How to ignite the boiler?

To repair boilers that won’t fire up is ANOTHER WORLD. One wrong move and your boiler can break. Most of the faulty parts – ignition lead, probe, spark generator, or broken diaphragms, all need minor repair by the skilful heating engineer.

Green Homes Grant Scheme – Energy Saving Vouchers

Green Homes Grant Scheme

UPDATE: “Boilers not to be included” says Martin Lewis (MoneySavingExpert)

Martin Lewis has reported that the new Green Homes Grant Scheme will not be able to be used for the purchase of new boilers. You may still be entitled to a boiler grant (benefits related), apply here. If you do not claim benefits, considering buying your new boiler online and paying monthly via a website such as Heatable.co.uk.

Reference: https://www.moneysavingexpert.com/news/2020/07/homeowners-to-receive-p5-000-vouchers-to-improve-energy-efficien/

——

Original article below

The UK government has just announced the Green Homes Grant scheme worth a mammoth £2billion, which is part of a larger green investment package worth £3billion.

The new grant has been made available to help homeowners and landlords pay for green home improvements, which includes upgrading old boilers to new, more energy efficient models.

Green Homes Grant – How Does it Work?

From September 2020 both homeowners and landlords in England will be able to apply for a grant worth up to £5,000, and £10,000 for the most deprived households.

To receive the grant, homeowners will need to apply online and will be directed to approved local suppliers who will provide a quote. Once work has been agreed upon, you will receive a voucher to cover the Government’s portion of the cost.

Low income households will not be expected to contribute anything to the cost and may be entitled to green home improvements up to the cost of £10,000.

How Much is the Grant?

The grant aims to cover the costs of 66% (two-thirds) of any work completed that meets the requirements. For instance, for the installation of a new boiler costing £2,000, you could potentially expect to receive a £1,333 voucher to help towards the costs.

Grants for a New Boiler

The purpose of the Green Homes Grant scheme is to help homeowners and landlords make their homes more energy efficient. This means that any work that helps to achieve this is approved for the new grant.

This includes home improvements such as the installation of new windows, insulation and the replacement of old, inefficient boilers.

New boiler models are much more efficient than those of yesteryear, being able to do their job using less energy and releasing less harmful emissions into the environment.

As Power to Switch highlights, if your boiler is more than 6 years old – and if older than this, is worth replacing with a newer model.

Why?

Newer models are 95% efficient, while older models are typically between 60% -70% efficient, helping you to make your money go further and reduce harm to the environment.

What is the Purpose of the Grant?

The government has stated that this new scheme aims to help stimulate the economy while at the same time, helping to make 650,000 homes more energy efficient. This is estimated to help the average home save £300 a year on bills.

This is also in line with a legally agreed upon target to cut greenhouse gas emissions to net zero by 2050.

What about Renters?

Currently, the announcements made by the Government about the green grant have stated that it will only be available to homeowners and landlords.

The Government opposition has pointed out this discrepancy in the scheme, highlighting that it will mean an estimated one third of the population will not be able to benefit from the scheme.

Applying for a free boiler grant in 2020 – is it still possible?

In short, absolutely.

The UK governments free boiler scheme has been running for some time now (Energy Companies Obligation). Over the years, the goal posts have been moved, however, funding is still available for replacement boilers in 2020.

What is the criteria to apply for a free boiler grant in 2020?

  • You will need to be a home owner (private tenants and landlords are now no longer able to apply)
  • You will need to be in receipt of one of the following benefits;
    • Universal Credit
    • Pension Credit
    • Child Tax Credit
    • Working Tax Credit
    • Income Support
    • ESA
    • JSA
    • Armed Forces Independence Payment
    • Attendance Allowance
    • Carers Allowance
    • Disability Living Allowance (DLA)
    • Severe Disablement Allowance
    • War Pensions Mobility Supplement
    • Industrial Injuries Disablement Benefit
    • PIP (Personal Independence Payment)
    • Constant Attendance Allowance
  • You will need to have a Mains Gas boiler in your home (funding is no longer available for Oil, LPG, or Electric Boilers)
  • Your existing boiler will need to be at least 8 years old (be broken, or not condensing)

That’s it.

Will the boiler be completely free?

Sometimes it can be, sometimes it can’t.

The grant, or amount of funding which you can claim is determined by the size of your home.

If you have a very in-efficient boiler and a large in-efficient home, more funding will be made available for you as the carbon savings will be high. In most cases, the boiler grant funding will cover the entire cost.

If you have a smaller home, the carbon savings will be lower, meaning less funding can be claimed. This means you will be required to contribute to the final cost.

If I am able to qualify for a free boiler grant in 2020, who gets the funding?

Once you’ve applied for a grant online (use the following link; https://boilergrants.org.uk/postcode.php), you will be contacted by a local approved company. They will discuss the process over the phone, and arrange a home visit. Once they’ve calculated there amount of funding which can be claimed, they will be able to advise you if your boiler grant will be fully funded, or let you know the amount which you would need to contribute.

If the contribution which is required is too high, there is no obligation to proceed with the installation of your new boiler.

The funding will go directly to the installation company, you will not receive the grant funding directly.

How long will it take to apply for a free boiler grant and have the boiler installed?

Not long at all.

You can apply online for a boiler grant in under 60 seconds.

Typically, you should expect the whole process to take around 2 weeks from the start of your boiler grant application to your free boiler being installed.

If I don’t quality for a free boiler grant, what are my options?

Firstly, try your local council. They run there own schemes (LA Flex etc).

Secondly, you could look in to pay monthly options. Websites such as Heatable.co.uk allow you to get a fixed price on a new boiler online, and you can apply for a finance within minutes. APR rates are typically around 9.9%, but 0% options are also available. They’re able to install new boiler anywhere in the UK within 24 hours, which is great if you’re in an emergency.

Revolutionary price comparison website is set to save boiler buyers’ a bomb

Heatable.co.uk is a recently launched boiler price comparison website which allows consumers to browse the best deals available from top-rated boiler installers who’re able to help in their area. Users are then able to filter the results based on what’s important to them, such as price, boiler make, warranty length and more. What’s more, it even breaks the prices down in to both ‘out-right’ and finance options, to give buyers a better understanding of their options.

Heatable’s founder, Sam Price, says:

Heatable is going to change the way people buy their new boilers, for good. For the first time, consumers are able to find the best deal without having to handle the pushy sales calls and dodgy salesmen at unsociable hours. Everything that they couldn’t do before, they now can, from the comfort and safety of their own homes. Within 30 seconds, they can get 30+ quotes which are totally bespoke to them.

In order to access the quotes, the user will need to answer some quick-fire questions about their home and it’s current heating system. Then, based on their answers, Heatable can determine which type of boiler will be required, how powerful it will need to be and calculate if it’s going to need any other additional safety attachments. It’s this simple, self service system which cuts out the need to meet multiple salesmen, who’ll all need to do the same thing.

Once submitted, Heatable matches it’s users up to multiple Gas Safe installers who’re able to help in their area, and present them with a range of different bespoke quotes which they’ll then be able to filter by brand (including Viessmann Boilers and Ideal Boilers), warranty length, rating, price and more. There’s different deals to cater for different budgets too, which really helps when trying to keep the costs down! To see reviews on the brands available, check out the Viessmann 050 Review and the Viessmann 100-W Review.

If a user finds a deal which they like, or if they have any questions about the package, finance payments etc, they can simply call the installers directly. There’s no call backs, or waiting around. Everything can be boxed off in real-time.

With funding for the ECO scheme being slowly cut, a website like Heatable could be just what the savvy boiler buyer needs.
