Remeha Boiler Fault Codes

Your boiler has switched itself off because an external safety device, such as a thermostat or pressure switch, has detected an issue and broken the electrical circuit.

Your boiler is struggling to ignite or keep the flame burning, and it is now trying to clear itself out before attempting to start again.

Your boiler has failed to light the flame needed to produce heat or hot water.

Your boiler has tried to light itself several times but has failed, likely because there is no gas supply or the ignition part is dirty or broken.

Your boiler has detected that there is not enough water inside the system to operate safely, or the internal pump is struggling to move the water around.
