What causes this fault?
This fault occurs when the boiler's internal computer detects a break in the constant electrical supply required to operate safely. The most common reasons are a simple tripped circuit breaker in your fuse box, a blown 3-amp fuse in the boiler's wall switch, or a failing component on the circuit board that is interrupting the power flow.
This fault is slightly more frequent during the winter months when power surges occur due to heavy load on the national grid or localized storm damage to power lines.
DIY fix possible
Check if other appliances in your home have powerEnsure the boiler's fused spur switch is turned onCheck your consumer unit/fuse box for any tripped switchesTurn the selector switch on the boiler to 'Reset' for five seconds, then back to the on position
