How to eliminate F1 error in boiler Fagor?
- Error: F1
- Description: The F1 error code in a Fagor boiler indicates a malfunction or anomaly in its operation, usually related to an ignition failure.
- Cause: The F1 error usually occurs during the initial start-up of the boiler or after a long period of inactivity when the gas and air mixture is not correct.
- Solution: To solve this problem, it is recommended to follow the following steps:
- Reset or restart your boiler to restore the default settings. This can be done by turning off the equipment and turning it back on.
- Check that there is enough gas and that the valves are correctly open to ensure proper pressure.
- Check the fan and pressure switch to make sure they are functioning correctly.
If after following these steps you are unable to solve the F1 error, it is recommended to contact a professional specialized in Fagor boilers to diagnose and repair the malfunction.
Boilers are efficient heating systems in most households, but no appliance is exempt from faults. Error codes in boilers often indicate simple problems, such as an air blockage. However, knowing the meaning of these codes can make the difference between an inexpensive repair and an expensive repair bill.
In this article, we will focus on the F1 error code in Fagor boilers. We will explain what this code means, the possible causes, and how to solve it.
What does the F1 error code mean?
Each brand and model of boiler has its own set of error codes. These codes indicate failures that prevent the boiler from operating efficiently and sometimes can be indicative of a major problem. However, if you have an F1 error code in your Fagor boiler, don’t worry!
The F1 error code in a Fagor boiler is a built-in signal to alert you that the boiler unit has stopped due to low water pressure in the boiler. Usually, a boiler loses pressure due to leaks or a problem with the boiler’s pressure gauge.
When boilers lose pressure, they don’t have enough force within the system to circulate the hot water that is responsible for your home’s central heating system.
If you are getting this error code, it is likely that your central heating system is not working effectively. But before you can fix the fault and enjoy a warm home again, you must first understand the root cause of the problem.
Causes of the F1 error code
Low boiler pressure
One of the most common causes of low boiler pressure is a leak or a slow loss of water pressure. Leaks can cause an almost instant drop in boiler pressure. On the other hand, the water pressure in a boiler will slowly decrease over time. Therefore, if you have had your boiler for a few years, this could be the cause.
You may notice a loss of boiler pressure by checking the boiler’s pressure gauge. The gauge should measure between 1 and 2 bars to operate effectively. But if the gauge shows less than 1 bar, it is a good indication that your boiler pressure is too low.
While normal pressure loss is easy to fix, leaks are more complicated and require a visit from a boiler engineer. Leaks can develop over time and are usually the result of loose joints and holes in pipes, radiators, or the boiler itself.
Broken or damaged water pressure sensor
Another reason why your boiler pressure may be low is a broken or faulty pressure sensor. To check for this problem, you need to assess your pressure gauge.
The pressure gauge should show between 1 and 2 bars, ideally at 1.5 bars. If you notice that the readings are at the optimal level but you still get an F1 error code on the boiler, you may have a defective sensor.
When the sensor is broken, it will start sending false pressure readings to the boiler’s printed circuit board (PCB). The PCB will receive the alert that the pressure is too low and display an F1 error code, causing the boiler to stop.
In this case, you will need to contact a boiler engineer and have them repair or replace the boiler’s pressure sensor.
How to solve the F1 error code
Check for water leaks
When you have a hidden water leak, you may notice that your boiler has constant low-pressure readings. A rapid drop in pressure can also indicate a sudden leak in the boiler, which needs to be fixed as soon as possible.
To increase the boiler pressure, you must check for water leaks before refilling it. If you don’t do this before adding water to your boiler, you can cause water damage that can affect the internal components of the boiler. When this happens, it may be necessary to replace the entire boiler.
If you notice that your boiler is losing pressure more frequently, a boiler maintenance specialist can help you locate the source of the problem.
The engineer will check for leaks in towel rails, copper pipes, and central heating radiators. They will also inspect loose joints and the boiler’s heat exchanger and pump to rule out internal problems that would require a complete reinstallation of the unit.
Alternatively, leaks may come from the network of pipes running through your home as part of your central heating system. Leaking pipes should be repaired as soon as possible, as they can cause damage to the floors and walls of your home if ignored for too long.
Repairing floors and walls is much more expensive than solving the boiler problem, so it is a good idea to regularly check your boiler for leaks, especially if there has been cold weather.
Refill the boiler
Once you have checked your heating system for leaks and faulty sensors, you may need to refill your boiler. This solution should only be done if the boiler has lost pressure over time and there are no other external problems.
Slowly refill your boiler and check the pressure on the pressure gauge. Adding more water can sometimes cause airlocks, so it is necessary to bleed the radiators while refilling to avoid this problem.
You may need assistance from someone to bleed the radiators while refilling. It is also important to check the gauge while bleeding to ensure that the pressure level stays between 1 and 2 bars.

Restart the boiler
These solutions will not automatically remove the F1 error code from your boiler. Instead, you will need to restart your system for it to work efficiently again.
If the F1 error code persists after applying these solutions, it may be time to call a certified boiler engineer to repair or replace your Fagor boiler.
Remember that it is important to follow the manufacturer’s instructions, and if you do not feel comfortable making the repairs yourself, it is always best to seek the help of a professional.
