What causes this fault?
This fault occurs when the boiler's main control board suffers an internal electrical failure, meaning it can no longer communicate with the gas valve or sensors. It is usually caused by aging electrical components reaching the end of their lifespan or a sudden power surge that damages the delicate circuitry. Because the 'brain' of the boiler is compromised, it shuts down immediately as a safety precaution.
This fault is slightly more common during the autumn and winter months when the boiler is first switched back on after a long period of inactivity, which can stress older electronic components.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
Avoid the next call-out bill
A cover plan would handle faults like F.60: no call-out fees, no surprise bills.
