A common culprit for this fault on Baxi boilers is a lack of pressure. If your system is set lower than 1.5 bar then it won’t operate correctly. Now, the quick fix is to top up the pressure using the filling loop. Once you’ve topped up the pressure, you’ll need to reset the boiler.
Why is my Baxi boiler not igniting?
If the boiler is not igniting, there is a possibility the valve is blocked, seized or there is damage in the wired connections. No Pilot Light: When the boiler is not igniting and the pilot light has gone out, this usually means debris has blocked the jet.
How do you fix a boiler that won’t ignite?
If you still can’t light your boiler, there could be debris blocking the jet. Boiler pilot light jets are relatively cheap to replace but can also be removed, cleaned and re-installed. Your heating engineer will be able to advise you on the best course of action and replace the jet accordingly.
Why is my boiler not kicking in?
Boiler won’t turn on (no power)
If your boiler won’t turn on, the first thing you should do is check other appliances and power supplies in your home to see if they are working. If they are, check your fuse box to see if any switches have failed or tripped.
How do you fix a flame failure on a Baxi boiler?
To reset the boiler, turn the selector switch to the R (Reset) position. Hold for at least 5 seconds and release. The fault code will be replaced with the boiler’s current temperature. At this point on a neon indicator boiler model, the flame failure light will stop flashing and will be replaced with the burner light.
How do I get the pilot light back on my boiler?
How do you relight the pilot light on a boiler?
- Turn the gas to ‘pilot. ‘
- Press and hold the reset switch for one minute and hold a flame to the pilot light at the same time.
- If all is working as expected, return any casing/doors and turn the gas from ‘pilot’ to ‘on.
Why won’t the pilot light come on?
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.
Can you manually ignite a boiler?
If there is no label, look at the top of the gas control knob. If the control knob has two settings, on and off, it is an automatic ignition system. A manual ignition will have three settings — on, off and pilot. Never attempt to light an automatic ignition system manually.
How do I know if my boiler pilot light is out?
How to Tell If the Pilot Light Is Out
- Locate the front cover panel on your furnace. It should be a little door that’s easily visible.
- If your pilot light is on, it should be easy to see your eyes will be drawn to the little flame.
- If you don’t see a flame, your pilot light is out.
- If there is a flame, check the color.
Why is my boiler giving me hot water but no heating?
If you’ve got hot water, but no central heating then there are more issues it could be if it’s not the thermostat or the boiler pressure. Common reasons for this particular fault are broken diaphragms and airlocks, or a motorised valve failing.
Why won’t central heating come on?
Check the Pilot Light A dirty or faulty pilot light is one of the main reasons a gas furnace won’t start.Make Sure Natural Gas Is Flowing into the Furnace If your furnace won’t start, it may be because the unit isn’t getting any fuel. Simply check the gas control valve to ensure it’s in the On position.
Why is my boiler on but no heating?
If your boiler works but the radiators are not heating up, then likely cause could be a faulty boiler pump or your central heating controls. If your boiler works but the radiators are cold, check that the thermostat or timer is working correctly.
Why does my boiler keep losing flame?
Delayed ignition can be caused by a range of problems, including a restricted or weak pilot light. Also, low gas supply pressure can mean that there is too little gas at the burners, resulting in ignition problems. Another possible cause is too much primary air. This is air that’s mixed with gas before it’s ignited.
Why do I have to keep resetting my Baxi boiler?
If you find that you keep having to reset your boiler, it’s likely that there could be a fault with your heating system. This fault could eventually lead to a more serious issue such as a boiler breakdown, so it’s best to seek out a solution as soon as possible.

Do Baxi still make back boilers?
Baxi are the creators of the original Bermuda Back Boilers and are the only brand of boiler to release a modern condensing boilers back boiler.
What is a Baxi back boiler?
Back boilers (also known as back boiler units or BBUs) became popular in 1966 with the launch of the original Baxi Bermuda. A back boiler is a small, compact boiler fitted at the back of an open fireplace hearth. It sits behind a gas fire and provides hot water and central heating to the property.
Is it hard to light a pilot light?
It’s not difficult to relight your gas furnace’s pilot light. As with these other appliances, it’s best to check with the manual first, but you can expect the process to be about as simple as it appears here.

The thermocouple always thinks the pilot is not lit, even if it is. To get hot water, I have to light the pilot, then hold the match on the thermocouple to trick it into thinking the pilot light is touching it. Once it’s warm enough, I pull the match out and turn the knob from “Pilot” to “On”.
What do you do when your pilot light goes out?
Your pilot light relies on your natural gas to stay aflame, so if your gas is shut off, your pilot light will go out. Simply turn your gas back on and either relight your pilot light yourself or call a professional.
Does gas still flow when pilot light goes out?
If your pilot light repeatedly goes out, this is a likely culprit. If this flame sensor should fail, gas will continue to flow even after the pilot light has been extinguished, causing a safety hazard, and requiring immediate repair.
