Troubleshooting the Dreaded Boiler A21 Fault

If your boiler is displaying the A21 fault code, it typically indicates a problem with the flame sensing electrode. This electrode is responsible for detecting whether the boiler burner has ignited successfully. One common reason for this fault is a build-up of dirt or debris on the electrode, causing it to malfunction. To troubleshoot this issue, try cleaning the electrode with a soft brush or cloth to remove any residue that may be interfering with its operation. If cleaning the electrode doesn’t solve the problem, you may need to have it replaced by a professional technician.

Another potential cause of the A21 fault is a faulty ignition lead. This component is responsible for providing the spark that ignites the boiler burner. If the ignition lead is damaged or worn out, it may not be able to generate the necessary spark, resulting in the A21 fault code being displayed. To troubleshoot this issue, carefully inspect the ignition lead for any signs of wear or damage. If you notice any issues, you should replace the ignition lead to restore proper functionality to your boiler.

In some cases, the A21 fault may be triggered by a problem with the boiler’s control board. This component is responsible for regulating the various functions of the boiler, including the ignition process. If the control board is malfunctioning, it may not be sending the correct signals to the flame sensing electrode or ignition lead, resulting in the A21 fault code being displayed. To troubleshoot this issue, you should have the control board inspected by a qualified technician. If necessary, the control board may need to be repaired or replaced to resolve the A21 fault.
