This signals an overheat condition. Another symptom is unusual noises from the boiler, like banging or gurgling. These are caused by the heat exchanger or water circulation issues.

The E110 fault might reduce water pressure. The boiler fails to circulate water through the system. The radiators may remain cold, and no hot water will be available at the taps. These symptoms are due to the system’s safety features. They are preventing damage from overheating.

How To Recognise The E110 Fault on Different Types of Baxi Boilers

Baxi Combi Boilers

In Baxi Combi boilers, the E110 fault will present itself as a total loss of heating and hot water. The control panel will show a fault code. The system will shut down to avoid overheating. Combi boilers are prone to pump issues and blockages. They can cause this fault to appear more often.

Baxi System Boilers

For Baxi System boilers, the E110 fault usually shuts down the heating system. You may notice that the radiators are cold. There is no hot water circulating through the system. In system boilers, the fault is often due to the thermostat or heat exchanger. This causes an overheat condition.

Other Baxi Boiler Models

Other Baxi models will also show the E110 fault code on their digital control panel. They will shut down as a safety measure. The symptoms are the same across these models. The fault indicates an overheating issue. It is caused by internal problems. These include blocked heat exchangers, faulty thermostats, and pump failures.

Next, we will suggest actions if your Baxi boiler shows the E110 fault code. This will help you manage the situation safely.

What to Do and How to Fix E110 Baxi Boiler Fault Code

If your Baxi boiler shows the E110 fault code, turn it off immediately. This stops the system from overheating further and prevents any potential damage. Next, check your boiler’s manual for the safe shutdown steps. Once the boiler is off, allow it time to cool down before inspecting any external components. If your boiler has reset instructions in the manual, follow them carefully to attempt a reset.

If the fault remains after a reset, or if unsure, contact a Gas-Safe registered engineer. Do not attempt internal repairs or open the boiler casing. This could void warranties and compromise safety. Overheating is serious. Only a qualified engineer should find the cause.

Safety Disclaimer

Never try to fix the E110 fault yourself beyond basic troubleshooting. This includes turning off the boiler and resetting it if the manual recommends it. Always use a Gas-Safe engineer to inspect and repair internal faults. Tampering with the boiler yourself can be dangerous and may violate safety regulations.

How to reset my Baxi boiler after the E110 fault code?

You can reset your boiler by following the reset instructions in your boiler’s manual. Once the system has cooled down, press the reset button as directed. If the E110 fault code reappears, turn the boiler off and contact a Gas-Safe engineer.

Should I turn the gas off if my boiler shows the E110 fault?

For the E110 fault, turning off the gas is usually not required. The boiler has shut down to prevent overheating. However, if you suspect a gas leak, you should turn the gas supply off and call an engineer immediately.

Where should I look for signs of gas or water leaks?

If the E110 fault occurs, check for water leaks near the boiler, especially around the pipes and valves. This fault makes gas leaks less likely. But, if you smell gas, turn off the gas supply and contact an engineer.

How long should I wait before calling an engineer?

Contact an engineer immediately if resetting the boiler does not fix the fault. Overheating is a critical issue. It must be fixed quickly to avoid further damage to the system.

Next, we will detail the main causes of the E110 Baxi boiler fault code. This will help you understand why it happens and how to prevent it.

Cost to Repair E110 Baxi Boiler Fault Code

You can expect to pay around £200 to £300 to repair the E110 Baxi boiler fault code. The cost to repair the E110 fault varies depending on the underlying issue. This typically covers the cost of parts and labour for minor repairs. If the problem is serious, like a blocked heat exchanger or a pump failure, the cost can rise to £300-£400.

For major work, like replacing key parts, the cost could be £500. These repairs take more time and require specialised parts. Also, the cost will depend on your location and the engineer’s rates. But, using a Gas-Safe engineer is essential for safety and legal reasons.

The 5 Major Causes of The E110 Baxi Boiler Fault Code

The E110 Baxi boiler fault code is due to overheating. This can result from various internal issues. The five main causes are: a faulty thermostat, a blocked heat exchanger, poor water circulation due to pump failure, low water pressure, and sensor malfunctions. Each issue affects the system’s ability to regulate temperature. This causes overheating and an automatic shutdown.

Faulty Thermostat

A faulty thermostat is one of the most common causes of the E110 fault code. The thermostat regulates the boiler’s temperature. It turns the heating element on and off. If it malfunctions, it may fail to detect the temperature. This could cause the system to overheat. Thermostat failure often requires replacement to restore normal function.

Blocked Heat Exchanger

The heat exchanger transfers heat from the burner to the water in the system. A blocked heat exchanger cannot operate efficiently. Limescale or debris causes the blockage. This blockage leads to a build-up of heat within the system, causing the boiler to overheat. Regular descaling and maintenance can prevent this issue from occurring.

Pump Failure

The circulation pump ensures that water flows properly through the heating system. If the pump fails, water will not move as it should, causing heat to build up inside the boiler. This lack of circulation commonly causes the E110 fault code. Stagnant water in the system can quickly overheat. A damaged or worn-out pump usually needs to be replaced to fix the problem.

Low Water Pressure

Low water pressure can cause the boiler to overheat. It prevents the boiler from working properly. If the system lacks pressure, the water won’t circulate. This makes the boiler work harder and overheat. Checking and maintaining the correct pressure levels can help avoid this issue.

Sensor Malfunctions

Temperature sensors monitor the boiler’s heat. They ensure it operates within safe limits. A sensor malfunction can send false readings to the system. This may cause it to overheat. Faulty sensors may require recalibration or replacement to restore proper monitoring.
