In this article, we’ll walk you through some common causes of the A21 fault code and how you can quickly fix it yourself.

Troubleshooting Your Worcester Boiler: A21 Fault Code

Is your Worcester boiler showing an A21 fault code? This error code typically indicates a problem with the boiler’s circulation pump. One common issue that can trigger the A21 fault code is a failed pump or a blockage in the pump system. To troubleshoot this issue, start by checking the pump for any visible signs of damage or blockages. You can also try resetting the boiler to see if that resolves the problem. If the fault code persists, it may be time to call a professional for further assistance.

Another potential cause of the A21 fault code in your Worcester boiler is a problem with the water pressure. Low pressure in the system can prevent the boiler from circulating water effectively, leading to the A21 fault code. To address this issue, check the boiler’s pressure gauge and ensure it is within the recommended range. If the pressure is too low, you can try topping up the system yourself using the filling loop. However, if you’re not comfortable doing this, it’s best to contact a qualified engineer to avoid causing further damage to your boiler.

If you’ve checked the pump and water pressure and the A21 fault code is still persisting, it may be due to a faulty sensor or wiring issue. In this case, it’s best to contact a professional boiler technician to diagnose and fix the problem. They will have the expertise and tools needed to identify the root cause of the fault code and get your Worcester boiler back up and running smoothly.
