Troubleshooting the E12 Boiler Fault: A Quick Guide

When faced with the dreaded E12 boiler fault, the first thing you should do is check for any obvious issues such as a lack of water in the system or a faulty thermostat. Make sure all valves are open and that there are no leaks in the pipes. If everything seems to be in order, it’s time to reset the boiler by turning it off and on again. This simple step often helps to resolve minor faults and get your boiler back up and running smoothly.

If resetting the boiler doesn’t do the trick, it’s time to delve a bit deeper into the issue. Check the pressure gauge to ensure it’s at the correct level – typically between 1 and 1.5 bar. If the pressure is too high or too low, you may need to adjust it accordingly. Additionally, make sure the gas supply is connected and that the pilot light is on. If you’re still experiencing issues, it may be time to call in a professional to take a closer look at your E12 boiler.
