How To Reset a BAXI Boiler

Sometimes in life, you need to perform a hard reset. Whether it’s a dodgy computer or an annoying glitching cell phone, a device that also requires a reset is your home’s boiler.

However, every boiler brand has its methods of being reset. If you own a BAXI boiler, there are some differences between the models and other brands when resetting them.

With BAXI boilers, several error codes indicate that it has shut down or initiated lockout mode, which requires fixing the problem and resetting the unit.

Some of these codes include:

• E110 – Overheat Shutdown: This code appears when the boiler’s safety thermostat detects an over-temperature condition, possibly due to poor circulation or a malfunctioning pump. ​
• E119 – Low Water Pressure: Indicates that the system’s water pressure has dropped below the required level, often due to leaks or bleeding radiators.
• E125 – Circulation Fault: Occurs when there’s inadequate water circulation in the primary circuit, potentially caused by airlocks or pump issues. ​
• E130 – Flue Overheat: Triggered when the flue gas temperature exceeds safe limits, possibly due to blockages or poor ventilation.
• E133 – Ignition Failure: Indicates that the boiler has failed to ignite, which could be due to gas supply issues, faulty ignition components, or a frozen condensate pipe.
• E160 – Fan Fault: This signifies a problem with the fan or its wiring, affecting the boiler’s ability to expel exhaust gases.
• E168 – PCB Lockout: This code suggests a fault with the Printed Circuit Board (PCB), possibly following a power supply issue.

These error codes can differ depending on your boiler’s model and year, so it is always best to check the unit’s manual for the meaning.

Resetting your BAXI boiler is done mainly to recover it from a lockout mode.

As you can imagine, resetting your boiler is usually a straightforward task, but there are some general steps you can follow to ensure you’re doing it correctly.

Performing A Reset Of A BAXI Boiler

For BAXI boilers, there are three main reset procedures. These include:

BAXI Boilers With A Reset Button

BAXI boilers with a reset button include:

• Baxi 100 Combi
• Baxi 200 Combi
• Baxi 400 Combi
• Baxi 600 Combi
• Baxi 800 Combi
• Baxi Platinum Combi
• Baxi Duo-tec Combi
• Baxi EcoBlue Advance Combi
• Baxi Main Eco Compact (Main brand, Baxi group)

BAXI Boilers With A Reset Dial Or Selector Switch

BAXI boilers with a simple dial on their front panel include the following:

• Baxi Solo (e.g., Solo 2, Solo 3, Solo HE)
• Baxi Bermuda (some older models)
• Baxi Genesis
• Baxi Main HE (some variants)
• Baxi Combi 80e / 105e
• Baxi Megaflo System (some models)
• Baxi WM Series
• Baxi Barcelona
• Baxi Performa System or Combi
• Baxi EcoBlue Heat or System (some models have dials rather than buttons)

While some may be older, the dial interface is incorporated into newer models.

Baxi Boilers With A Light-Up Reset Button

The last reset option for the BAXI boiler range is the light-up reset button. The models that utilise this light-up button include:

• Baxi 600 Combi
• Baxi 800 Combi
• Baxi Duo-tec Combi (some later models)
• Baxi Platinum+
• Baxi Assure Combi
• Baxi Main Eco Compact (Main is Baxi’s sub-brand)

Now that we know which BAXI boiler model requires different reset steps, let’s review the steps you should take when resetting it.

Step One: Error Code

Before you reset your BAXI boiler, make sure to take note of the error code. You can do this by snapping a photo or jotting down a note in your boiler’s manual.

Missing this step won’t affect the reset process; it is just in case the issue reoccurs or you need to contact a Gas Safe registered engineer.

Step Two: Reset Boiler

With three different methods to reset your BAXI boilers, the reset via button is very easy.

To use the reset button, press and hold the reset button for just 2 seconds until the error message stops flashing. After releasing the button, see if the boiler reboots and the error clears.

With the dial models, turn the selector dial to the reset position and hold for around 3 seconds. This should reset the boiler and clear the error code on the screen.

If your boiler has the reset light button alongside the error code light, you must hold the reset button for five seconds. Afterwards, the error light should return to green.

If everything has gone perfectly, reigniting the boiler will take a minute or two.

After the boiler has returned to its usual state, check that the hot water and heating systems are working correctly.

However, if this has not removed the error code and it has reappeared, you can consider doing a manual reset.

Step Three: Turn Off The Power

While this additional step won’t be in the manual, you might need to turn off your boiler at its power source.

Close to your boiler should be a fuse spur. If you’re uncertain what a fuse spur is, it’s a square white box with a large switch in the middle.

Flip this switch on and off. You should allow a few seconds for the boiler to shut down.

Sometimes, a boiler is simply plugged into a socket, requiring you to flip the switch.

If you cannot locate your boiler’s plug point, try switching it off and on at the distribution board, also known as:

• Panelboard
• Circuit breaker panel
• Breaker panel
• Electric panel,
• Fuse box,
• Or DB board/box.

Once you’ve turned the power back on, your BAXI boiler should be reset successfully.

But if you still get the same error message, you will want to do some more troubleshooting.

Further Troubleshooting If Your Boiler Fails To Reset

As with everything in life, the simplest tasks can become more complicated. If your boiler is refusing to reset, you will want to do a few quick checks:

Identify The Error Code

You only want to reset your BAXI boiler if it is in lockout mode. Make sure to double-check what the error code means.

Usually, the manufacturer will include a comprehensive list of error codes in their manual.

If you’ve lost your manual or are struggling to find a solid answer, you can do some simple checks before calling in a professional.

Check The Gas Supply

A simple check is to see if your home’s main gas supply valve is fully open. Your home’s gas mains should be fully open.

Another way to check for a gas supply issue in your home is to turn on other gas appliances, such as a kitchen stove.

If you suspect a gas supply issue, contact your gas provider. There might be a local supply issue in your area.

However, if you smell gas, turn off the supply immediately and call for help.

Check Water Pressure

Most BAXI boilers have a pressure gauge on the front panel as a dial or analog gauge, a digital screen, or, on older models, a physical gauge under the unit.

The ideal reading is between 1.0 and 1.5 bar when the system is cold.

If the water pressure reading is below 1.0 bar, your boiler might need to be repressurised

On the other side of the scale, if your BAXI boiler’s reading is too high, above 2.5 bar, you will want to bleed a radiator in your home to lower the pressure.

Check The Power Supply

It could be an electrical issue if your boiler has not turned back on after the reset.

Ensure the boiler is plugged into a working power socket and no circuit breakers have tripped.

For those who turned off their boiler via the fuse spur switch, a fuse could have blown if flipping the switch had not resulted in power feeding to the boiler.

While most of these checks can be completed relatively quickly, if you’re struggling to reset your boiler, we highly recommend calling an expert for help.
