Troubleshooting the A28 Fault on Your Worcester Boiler

When your Worcester boiler displays the A28 fault code, it typically indicates a problem with the gas valve or gas supply. The first thing to check is if the gas supply has been interrupted. Make sure that the gas supply is turned on and that there are no issues with the gas line. If the gas supply seems to be fine, the next step is to check the gas valve. Ensure that the gas valve is open and functioning properly. If you notice any issues with the gas valve, it may need to be replaced by a professional.

Another common cause of the A28 fault on a Worcester boiler is a problem with the ignition. Check to see if the ignition is working correctly by listening for the clicking sound when the boiler is trying to ignite. If you don’t hear the clicking sound or if the ignition is not sparking, there may be an issue with the ignition electrode or the ignition lead. In this case, you may need to clean or replace these components to resolve the A28 fault.

If you have checked the gas supply, gas valve, and ignition and are still experiencing the A28 fault on your Worcester boiler, it may be a more complex issue that requires professional assistance. At this point, it’s best to contact a qualified heating engineer or the manufacturer’s customer service for further diagnosis and repair. They will be able to identify the root cause of the A28 fault and provide you with the necessary steps to resolve it.

Easy Steps to Reset Your Worcester Boiler A28 Fault

To reset the A28 fault on your Worcester boiler, you first need to locate the reset button on the boiler. The reset button is usually a small red button located on the front panel of the boiler. Press and hold the reset button for a few seconds until you hear a click. This should reset the boiler and clear the A28 fault code. Once you have reset the boiler, wait a few minutes for it to restart and check if the fault has been resolved.

If resetting the boiler does not clear the A28 fault code, you may need to power cycle the boiler. To power cycle the boiler, turn off the power supply to the boiler at the main switch or fuse box. Wait for a few minutes before turning the power back on. This simple step can sometimes resolve the A28 fault and get your Worcester boiler back to working order. If the fault persists after power cycling the boiler, it’s best to seek professional help to avoid any further damage.

By following these easy troubleshooting steps and the simple reset process, you can quickly address the A28 fault on your Worcester boiler and ensure that your heating system is back up and running efficiently.
