Troubleshooting Boiler Woes: A21 Error Code

When faced with a boiler fault displaying the A21 error code, the first step is to check the water pressure. Low water pressure is a common culprit for this error and can be easily remedied by topping up the system. Simply locate the filling loop on your boiler and slowly add water until the pressure gauge reaches the recommended level. Once the pressure is back to normal, reset your boiler and see if the fault has been resolved.

If the A21 error persists after adjusting the water pressure, the next step is to check the system for any airlocks. Airlocks can prevent water from circulating properly, leading to heating issues and error codes like A21. To release any trapped air, locate the bleed valve on your radiators and use a radiator key to bleed out the air. Be sure to have a towel handy to catch any water that may escape. Once the airlocks have been removed, reset your boiler and see if the fault has been cleared.

If you’ve checked the water pressure and removed any airlocks but the A21 error code is still haunting your boiler, it may be time to call in a professional. A qualified heating engineer will be able to conduct a more thorough investigation of your system to pinpoint the root cause of the fault. While it may be tempting to try and fix the issue yourself, sometimes it’s best to leave it to the experts to ensure a safe and effective repair.
