BoilerFaultCodesThe 6 most common faults
Your boiler has detected that the water pressure inside the system is currently too low to operate safely, causing it to shut down to prevent damage.
Locate the filling loop (usually a silver braided hose with one or two valves) connected to the boiler pipes.Gradually open the valve(s) to allow mains water into the system until the pressure gauge reads between 1.0 and 1.5 bar.Close the valve(s) tightly and restart your boiler.
Your boiler has lost its electrical power supply or its internal control board is not receiving electricity.
Check if your main household consumer unit (fuse box) has tripped.Ensure the boiler's external isolation switch (usually a fused spur) is turned on.Check if other appliances in the house have power to rule out a local power cut.
Your boiler has detected that there is not enough water pressure or flow to operate safely and has shut down to prevent overheating.
Check the pressure gauge on the boiler or pipework to see if it is below 1.0 barLocate the external filling loop and slowly top up the system until the gauge reads between 1.0 and 1.5 barBleed any trapped air from your radiators and then re-check the pressure gaugePress the 'Reset' button on the boiler control panel
Your boiler has detected that there isn't enough water pressure or flow inside the system to operate safely.
Check the pressure gauge on your system; it should typically be between 1.0 and 1.5 bar.If the pressure is low, use the external filling loop valves to top up the water level.Ensure all radiator valves and isolation valves are fully open.Reset the boiler once the correct pressure is reached.
Your boiler has shut down because it has detected an unsafe build-up of heat or a lack of water circulation within the system.
Check that your system water pressure is between 1.0 and 1.5 barEnsure all radiator valves and isolation valves are fully openPress the 'Reset' button on the control panel once the boiler has cooled down
Your boiler is not firing up because it cannot detect an active call for heat or there is an issue with the electrical power supply reaching the unit.
Check that your room thermostat is turned up high and has fresh batteries if neededEnsure the boiler's main power switch is turned on and the fuse in the wall spur hasn't trippedCheck that your programmer or timer is set to an 'on' period
on the Remeha Quinta 85
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 Remeha 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
