BoilerFaultCodesThe 6 most common faults
Your boiler is currently completely unresponsive because it is not receiving any electrical power.
Check that the boiler isolator switch (usually a white switch near the boiler) is set to the ON position.Check your home's main fuse box (consumer unit) to see if any circuit breakers have tripped.Locate the fused spur next to the boiler and check if the replaceable fuse inside has blown.
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 or a small valve with a lever near the pipes under the boiler.Open the valve(s) to allow cold mains water to enter the system until the pressure gauge on the front of the boiler reads between 1.0 and 1.5 bar.Close the valve(s) tightly and restart the boiler.
Your boiler is not receiving any power, which means it cannot turn on to provide heating or hot water.
Check that the boiler's fused spur switch on the wall is in the 'on' position.Check your consumer unit (fuse box) to see if the circuit breaker for the heating system has tripped.Check the external plug fuse if the boiler is connected via a standard socket.
Your boiler has stopped working because it has detected an issue with its water pressure or internal sensors, preventing it from safely heating your home or water.
Check the boiler pressure gauge on the front panel; if it is below 1.0 bar, use the filling loop to top it up to between 1.0 and 1.5 barTurn the boiler off at the mains for 60 seconds to reset the electronic faultTurn the boiler back on and observe if the error clears
Your boiler has lost all power and is effectively switched off, preventing it from heating your home or water.
Check that the main boiler isolation switch (usually a fused spur nearby) is turned on.Inspect your home's consumer unit (fuse box) to see if a trip switch or RCD has flicked to the off position.Check if the fuse within the boiler's local connection unit has blown and replace it if necessary.
Your boiler is currently idle because it is not receiving a signal from your thermostat or timer to start heating.
Check your room thermostat and ensure the temperature set point is higher than the current room temperature.Verify that your external timer or programmer is set to 'On' and that the current time is set correctly.Replace the batteries in your wireless thermostat if applicable to ensure it is communicating with the receiver.
on the Ferroli Arean
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
