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
