Your boiler is undergoing a system reset, which means it is attempting to restart itself after detecting an internal error or interruption.
This fault should be looked at by a Gas Safe engineer within the next week or two. It may get worse if left.
Technical description: The boiler resets
What causes this fault?
This fault occurs when the boiler's internal computer experiences a software glitch or a momentary loss of communication with its sensors. It is frequently triggered by a faulty control board or an incorrect reading from an outside temperature sensor that confuses the system's logic. The 'rE' code signifies that the boiler is stuck in a loop trying to reboot itself to clear these electronic errors.
DIY fix possible
