Troubleshooting the Annoying A21 Fault on Your Boiler

Is your boiler displaying the dreaded A21 fault code? The first step in troubleshooting this issue is to check the pressure gauge on your boiler. If the pressure is too low, it can trigger the A21 fault. Simply refill the boiler with water to the correct pressure level and reset the system to see if the fault clears. If the pressure is normal, the next step is to check for any leaks in the system. A leak could be causing the pressure to drop, triggering the A21 fault. Repair any leaks and reset the system to see if the fault is resolved.

Another common cause of the A21 fault is a faulty pressure sensor. If you’ve checked the pressure and there are no leaks in the system, it’s possible that the pressure sensor is malfunctioning. In this case, you may need to replace the sensor to clear the A21 fault. If you’re not comfortable doing this yourself, it’s best to call a professional to ensure the sensor is replaced correctly. By troubleshooting these common issues, you can hopefully say goodbye to the A21 fault on your boiler and enjoy a warm and cozy home once again.
