What causes the Worcester Bosch POINT L fault?
This fault occurs when the boiler's control system attempts to start the heating process but fails to detect a sustained flame. The most common reason is that the gas valve isn't opening correctly to deliver fuel, or the ignition system is failing to provide the spark needed to light the burner. As a safety precaution, the boiler stops trying to fire to prevent unburned gas from building up.
