BoilerFaultCodesThe 6 most common faults
Your boiler has shut down because the water inside has become too hot, which is usually caused by a blockage or restricted water flow.
Check that all radiator valves are fully open.Ensure the boiler's service valves (underneath) are in the open position.Press the 'Reset' button on the control panel to restart the system.
Your boiler has switched itself off because the water pressure is too low for it to run safely.
Locate the filling loop (usually a flexible silver hose) underneath or near the boiler.Slowly open the valves until you hear water flowing and the pressure gauge rises.Close both valves tightly when the pressure reaches between 1.5 and 2.0 bar.
Your boiler has shut down because the internal water pressure has risen too high, likely due to overfilling or a valve being left open.
Check that the filling loop valves under the boiler are fully closed.Bleed water from a radiator using a bleed key to lower the system pressure.Monitor the pressure gauge until it returns to between 1.0 and 1.5 bar.Restart the boiler using the reset button.
Your boiler has failed to light because it cannot detect a gas supply or a flame, resulting in the system shutting down for safety.
Check that your gas meter is topped up and the emergency control valve is in the 'on' positionVerify if other gas appliances in your home, such as a hob, are working correctlyPress and hold the 'Reset' button for 3 to 5 seconds to clear the fault
Your boiler thinks a flame is burning even though it hasn't released any gas yet, which has caused it to shut down for safety.
Locate the 'Reset' button on the boiler control panel.Press and hold the Reset button for 3 seconds.Wait to see if the boiler restarts; if the error returns immediately, call a gas safe engineer.
Your boiler has shut itself down because it is receiving conflicting readings from its internal temperature sensors.
Press and hold the 'Reset' button for 3 seconds to clear the lockoutCheck if your radiators are bled and the system pressure is between 1.0 and 1.5 barIf the code returns immediately after resetting, you must call a Gas Safe engineer
on the ECA Confeo Premix HCH
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 ECA 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
