Ideal No Power to Boiler

Boiler display completely dead, no lights or response

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blown 3A fuse in fused spur, Tripped MCB at consumer unit, Faulty mains cable or spur, Internal PCB failure

Safety first: Do not open the boiler case. Work only on external electrical accessories if you are competent.

User checks:

Consumer unit: Check that the circuit breaker feeding the boiler is not tripped. Reset if necessary.
Fused spur: Ensure the spur switch is ON. Turn off, remove the 3A fuse, inspect, and replace if blown.
Other power: Confirm other electrical appliances in the area work to rule out a wider power cut.

If the boiler remains dead, an engineer should test the internal fuse and PCB and replace faulty components.
