What causes the Ideal 460 fault?
This fault occurs when the boiler's main control board suffers a hardware failure, meaning it can no longer send or receive instructions to vital components like the pump or gas valve. The most common reason is an electrical short-circuit or component degradation on the circuit board itself, which prevents the 'brain' of the boiler from functioning correctly.
