Troubleshooting the Pesky F23 Fault on Your Boiler

If you see the F23 fault code flashing on your boiler, the first thing to check is the pressure gauge. Low pressure is a common culprit for this error message, so make sure to top up the water level in your system. Simply open the filling loop valve and watch the pressure gauge rise to the optimal level. Once the pressure is back to normal, reset your boiler and see if the fault code disappears.

Another common reason for the F23 fault on your boiler could be a faulty pump or a blocked pipe. Check for any obstructions in the pipes leading to and from your boiler, and ensure that the pump is working correctly. If you suspect a pump issue, it may be best to contact a professional to have it repaired or replaced. Keeping your boiler well-maintained is key to preventing future faults like F23 from occurring.

If you’ve tried everything and the F23 fault code still persists, it may be time to check the condensate pipe for blockages. A blocked condensate pipe can cause your boiler to shut down and display error codes like F23. Simply clearing out any debris or obstructions in the pipe should do the trick. Once you’ve done this, reset your boiler and voila – your F23 fault should be a thing of the past!
