Technical description: Reset key fault – replace fascia PCB
What causes this fault?
This fault occurs when the reset button on the boiler's control panel becomes physically stuck or experiences an electrical short circuit. It is often caused by the delicate internal switch on the circuit board wearing out or failing after repeated use, leading the boiler to believe the button is being held down permanently.
Engineer required
This fault requires a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
