What Causes the E110 Fault Code?

Several factors can trigger the Baxi E110 fault on your boiler.

1. Low Water Pressure

Low water pressure, often below 1.0 bar, is one of the most frequent causes of the E110 Baxi fault. When the system pressure falls below this level, the boiler struggles to circulate water effectively, leading to overheating.

2. Trapped Air in Radiators
Air pockets in your radiators can disrupt water circulation, causing heating issues and contributing to the boiler's overheating.

3. Faulty Temperature Sensors

Temperature sensors that give incorrect readings can mistakenly signal overheating, even when the system is functioning normally.

4. Circulation Problems
Issues with the pump or diverter valve can restrict water movement within the system, causing the boiler to overheat.

5. Gas Supply Issues
Disruptions in your gas supply can hinder proper combustion, affecting the boiler's efficiency and resulting in overheating.

Identifying the root cause of the fault code is the first step toward resolving the issue. Once you know what's causing the Baxi E110 error, you can take action to fix it.

How Do You Fix the E110 Baxi Error Code?

Now that you understand why the Baxi E110 fault code occurs, you're ready to follow these troubleshooting steps:

1. Reset Your Boiler
Start by resetting your boiler. This process gives your system a fresh start and often clears minor issues. However, remember that this is only a temporary solution unless the cause of the fault is fixed.

2. Check and Adjust the Water Pressure
Inspect the pressure gauge on your boiler.

If Pressure is Low: Top it up using the filling loop. Open the valves on the filling loop and allow water into the system until the pressure gauge reaches the correct level. Don't forget to close the valves afterwards.

3. Bleed Radiators to Remove Air
You can use your radiator key to bleed any trapped air from your radiators. Place a container below the bleed valve, turn the key to release the air, and wait until water flows steadily. This helps improve water circulation.

4. Inspect Temperature Sensors
Make sure that the temperature sensors are properly connected and functioning. If you suspect they're faulty, a professional heating engineer can test and replace them.

5. Resolve Circulation Issues
If circulation problems stem from a pump or a diverter valve malfunction, you will need the expertise of a gas heating engineer to investigate and fix the issue.
