The Baxi E119 fault code typically points to problems with low water pressure in the central heating system. Key issues include leaks, pressure gauge readings, valve problems, and expansion vessel complications.
Leaks in the central heating system are a common reason for the E119 error code. Even small drips from pipes, joints, or the radiator can cause the pressure to drop. Over time, these leaks can worsen, leading to further pressure loss. Regularly inspecting the system for visible signs of water damage or puddles can help identify and fix leaks early. Using a professional to inspect areas that are not easily accessible is also advisable to maintain the system's integrity. In serious cases, repeated leaking might indicate more significant issues with the boiler or pipework, necessitating a more thorough investigation and repair.
The pressure gauge on the boiler is crucial for diagnosing the E119 fault code. A typical Baxi boiler operates best at a pressure between 1 and 1.5 bar. If the gauge shows a reading below this range, it triggers the E119 error. Regularly checking the pressure gauge helps catch low levels before they become problematic. If the pressure constantly drops even after repressurising, there may be an underlying issue that needs professional attention. Additionally, a faulty gauge can give incorrect readings. Ensuring the gauge itself is in good working condition is important for accurate monitoring and maintaining the boiler's performance.
Problems with the filling loop valves or end caps can also lead to an E119 error code. The filling loop is used to top up the boiler with water, and if the valves are not fully closed, it can cause pressure to drop. Similarly, damaged or improperly sealed end caps can result in water leaks, impacting the pressure. Checking the position and condition of these components can help prevent unnecessary pressure loss. Ensuring that valves are closed properly after maintenance and inspecting for any visible damage can reduce the likelihood of encountering this fault code. If necessary, replacing worn-out valves or end caps can address persistent pressure issues.
The expansion vessel in a boiler absorbs excess pressure caused by heated water expanding. If the vessel is faulty or the internal air charge is incorrect, it can lead to pressure problems and the E119 error code. Signs of expansion vessel issues include frequent pressure drops and the pressure gauge showing wide fluctuations. Regular maintenance of the expansion vessel, such as checking and correcting the air charge, can prevent these issues. In some cases, the vessel might need to be replaced if it is unable to maintain the correct pressure. Properly functioning expansion vessels are essential for the stable operation of the central heating system.

Addressing the E119 fault on a Baxi Combi Boiler primarily involves checking and adjusting the system pressure. This may include repressurising the boiler, checking for water leakage, bleeding the radiators, and inspecting the filling loop.
The E119 fault on a Baxi Combi Boiler often indicates low pressure. To repressurise the boiler, first locate the pressure gauge on the front of the unit. It should read between 1 to 1.5 bar. If it’s below this level, you need to add water to the system.
To do this, find the filling loop, which is usually a silver, flexible hose under the boiler. Turn the valves on this hose to allow water to flow into the system. Keep an eye on the pressure gauge and stop filling once it reaches the desired level. Be sure to close the valves securely after you’re done.
Low pressure can also result from a water leak in the central heating system. Inspect all visible pipes, radiators, and connections for signs of leakage. If you find any, it may require a professional to repair it.
Pay special attention to the pressure relief valve, which is a common leak point. If it's faulty, it can cause continuous pressure drops. You might spot a leak by looking for pooled water or damp spots around the valve.
If no visible leaks are found, adding a sealant to the system may temporarily plug small, internal leaks. However, this is not a permanent fix and professional help should be sought.
Air trapped in the radiators can lower the system pressure, causing the E119 fault. To bleed the radiators, you will need a radiator key or a flathead screwdriver.
Turn off the heating system and allow the radiators to cool. Starting with the radiator furthest from the boiler, use the key or screwdriver to open the bleed valve slightly. You’ll hear a hiss as air escapes. When water begins to trickle out, close the valve. Repeat this process for each radiator in the system.
After bleeding, check the system pressure again as it may have dropped. You might need to repeat the repressurising steps.
The filling loop is crucial for maintaining system pressure. Inspect it to ensure it’s correctly connected and not damaged. If the loop is leaking or the valves are not fully closed, it can cause pressure drops leading to the E119 fault.
To check, ensure both ends of the flexible hose are tightly connected. There should be no visible damage or signs of wear. If the filling loop is faulty, replace it with a new one. If unsure how to do this, consult a qualified heating engineer.
Regularly checking these components can help maintain proper pressure and prevent the E119 fault from recurring.
