What's wrong with my Baxi boiler
Lack of pressure is the most common reason for boiler failures at Baxi. It won't work correctly if the pressure is lower than 1.5 bar. The quick solution is to increase your pressure by using the filling circuit. Leakages in the system are the most common reason why a boiler fails.
This is why my Baxi boiler isn't firing up.
Boiler not starting Common causes include overheating (110), fan failure (160), flue overload (E131), and an issue with your printed circuit board (PCB (E168).
Second, why is it necessary to constantly reset my Baxi boiler. These signals are signs that your boiler should be checked and repaired. The most common faults that could cause your boiler to need to be reset frequently are: Leaks in the heating system. A blocked plate heat exchanger.
Another question is: How do I reset my Baxi boiler?
Turn the selector switch to R (Reset) to reset the boiler. Hold the button for at least five seconds, then release it. The boiler's current temp will replace the fault code. The flame failure light on a neon indicator boiler model will cease flashing at this point and will be replaced by the burner light.
My boiler is not starting.
The boiler won't ignite: This is one of the leading causes of heat loss. The burner's gas jets will not ignite and no heat will be generated to warm the water. This could be caused by a malfunctioning pilot light or electronic igniter.

How do you reset the pilot light on a Baxi boiler?
To light the pilot: Looking through the pilot viewing window press the gas control knob fully inwards and hold. Press in igniter button and release. Repeat until pilot ignites. Continue to hold in gas control knob for approximately 15 seconds and then release.
Why does my Baxi Boiler keep overheating?
Basically, a boiler will overheat if either the boiler is faulty, for example, the boiler thermostat / PCB that doesn't switch off the gas valve and so the burner keeps going until the increase in temperature makes the overheat trip, or there is insufficent flow of water through the boiler it to take away the heat.
How do I get the pilot light back on my boiler?
Turn the gas control knob to the "pilot" position, then press down on the knob. Pressing down on the knob will release gas into the pilot light orifice. Insert a lit fireplace match or a butane candle lighter into the access hole and light the pilot light. Keep holding down the control knob button as you do this.
What model is my Baxi boiler?
Your boiler's serial number is typically located on the right sidewall of the boiler inside the cover. In older models, you may find a tag underneath the boiler that slides out so that you can read the serial number. If you still cannot locate the serial number, you can contact Baxi Customer Support at 844-422-9462.
Where is the reset button on my Baxi boiler?
Most Baxi boilers have a simple reset button on the front panel - locate this and press and hold the button for 1 to 3 seconds or until it's clear that the boiler has rebooted itself.
What temperature should my Baxi boiler be set at?
Your boiler controls explained
To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you've got your boiler running at the optimal temperature, you'll want to set the timer for when you need heating the most.How do you fix a flame failure on a boiler?
Turn the Central Heating Temperature Control Knob clockwise to increase or anticlockwise to decrease the boiler flow temperature. If Flame Failure Light is ON press the Reset Button. If Flame Failure occurs frequently consult your Installer. This indicates that the Burner has fired up and is heating your system.
How do I lower the pressure on my boiler?
Bleed your radiators. This reduces the pressure in your central heating system and therefore reduces the pressure in your boiler. Continue bleeding the radiator after you have expelled all the air from it until the pressure gauge returns to safe levels.
How do you bleed radiators?
Summary: How to Bleed a Radiator in 10 Easy Steps
- Turn on the central heating.
- Feel all the radiators in your home.
- Switch off the heating.
- Wait for the radiators to cool completely.
- Grab your supplies.
- Find the bleed valve.
- Loosen the bleed screw.
- Wait for the hissing to stop completely.
Why does my Baxi boiler lose pressure?
Your combi boiler can be losing pressure for a number of reasons. Pressure loss may be caused from a leak in the pressure relief valve, an issue in the expansion vessel, air in your system, or a leak in the heating pipework itself.
What pressure should my Baxi boiler be?
The normal operating water pressure for your boiler and central heating system is between 1.0 and 2.0 bar. If the pressure drops below 1.0 bar, you need to repressurise it. If the pressure goes above 3.0 bar, you will see water coming from the pressure relief valve (usually on an outside wall).
Is low boiler pressure dangerous?
The good news is that low boiler pressure is nothing to panic about and is not likely to cause any damage to your boiler. On the other hand, it can have a real effect on the efficiency and effectiveness of your heating system, making it hard to keep your house warm and costing you more on your energy bills.
How often top up boiler pressure?
Topping up once or twice a year is normal, but it will dilute the corrosion inhibitor, so maybe add some every five years.
What should boiler pressure be when heating is on?
When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure.
How do I reset my Baxi combi 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.
What happens if boiler pressure too high?
In the vast majority of cases – no. Most boilers will simply shut down via a safety device called a PRV (Pressure Release Valve), or break down when pressure is too high, for too long. The worst case scenario for most boilers suffering from high pressure will be a broken boiler and a soaked carpet.
Why does my combi boiler pressure keep rising?
Too much water in the expansion tank and too little air may also cause pressure to rise frequently. Simply close the valve between the expansion tank and boiler and then completely drain the tank. Open the water supply valves and refill the system. Pressure should remain stable during subsequent use.
