What to do as a Qualified Gas Engineer?
Here are a couple of steps to take that may resolve the E15 Fault “Gas Valve Error”:
Before taking the casing off the boiler
If you encounter the E15 error code on your Main Eco Compact boiler, a simple reset can often resolve temporary glitches. Locate the reset button or switch on the front of the boiler and press or toggle it to reset the system. Allow the boiler to restart and observe if the E15 error code persists. If the error code continues to appear, further troubleshooting may be required.
Check the Electricity: Electrical issues can sometimes trigger the E15 error code. Check the following components related to electricity:
- Make sure the switch fuse that supplies electricity to the boiler is operating properly. Verify the fuse to make sure it hasn’t tripped.
- Fuse on the PCB: The boiler’s printed circuit board (PCB) may have a fuse that is prone to blowing. Examine the PCB and verify the fuse’s integrity. Replace the blown fuse with a fresh one that has the same rating.
- Connecting Wires: Check the wire that connects the boiler to the switch fuse. Keep an eye out for any damage indicators, such as fractures, tears, burns, or wounds. The cable needs to be fixed or replaced if there are any problems.
Check the Gas: Gas-related issues can also trigger the E15 error code. Take the following steps to ensure a proper gas supply:
Check the Gas Supply:
