BoilerFaultCodesThe 6 most common faults
Your boiler has stopped working because the water pressure inside the heating system has dropped too low.
Locate the filling loop, which is a silver braided hose with one or two valves connecting your boiler to the mains water supply.Open the valve(s) slowly to allow water into the system until the pressure gauge on the front of the boiler reads between 1.0 and 1.5 bar.Turn off the valve(s) completely and ensure they are tightened to prevent future pressure loss.
Your boiler has stopped working because the water pressure inside the system has dropped too low to operate safely.
Locate the external filling loop, which is a silver braided hose with one or two valves connecting your boiler to the mains water supply.Open the valve(s) slowly to allow water into the system until the pressure gauge on the front of the boiler reads between 1 and 1.5 bar.Fully close the valve(s) and ensure no water is dripping from the connection.
Your boiler has stopped working because the water pressure inside the system has dropped too low, which is causing it to lock itself to prevent damage.
Locate the filling loop (a silver flexi-hose) underneath your boiler.Open the valves attached to the loop until you hear water flowing.Watch the pressure gauge on the front of the boiler until the needle reaches between 1 and 1.5 bar.Firmly close the valves to stop the flow.
Your boiler has stopped working as a safety precaution and needs to be manually reset to try and restart the system.
Locate the on/off/reset switch on the front control panel.Turn the switch to the 'reset' position and hold it briefly.Return the switch to the 'on' position and wait to see if the burner ignites.
Your boiler has stopped working because the water pressure inside the heating system has dropped too low.
Locate the filling loop, which is usually a flexible silver hose or two valves sitting underneath the boiler.Open the valves slowly to allow water into the system until the pressure gauge needle reaches the 1 to 1.5 bar mark.Close both valves tightly to stop the flow of water and check if the red light resets.
Your boiler has stopped working because the water pressure inside the heating system has dropped too low to operate safely.
Locate the filling loop (a flexible silver hose) underneath the boiler.Open the small valve(s) on the loop to allow water into the system.Monitor the pressure gauge on the boiler until it reaches the green zone (typically 1.0 to 1.5 bar).Close the valve(s) tightly to stop the flow.
on the Ferroli Falcon
Based on parts cited in our fault code database. Your engineer will confirm what's actually needed after diagnosis.
Call a Gas Safe engineer if…
- You can smell gas or see signs of a leak
- The Ferroli shows an Emergency or High severity code
- The boiler keeps locking out after repeated resets
- You've tried the DIY checks and the fault hasn't cleared
- There's visible water leaking from the boiler
- The flame is yellow or orange instead of blue
