Intergas Electrical Short / Earth Leakage

Boiler occasionally trips the household RCD or blows fuses

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

Water ingress onto PCB or wiring, Failing pump or fan motor, Damaged cable insulation, Faulty immersion heater (on system with cylinder)

Danger: Repeated tripping indicates a potentially serious electrical fault. Risk of electric shock or fire.

Do not repeatedly reset: If the RCD or fuse trips when the boiler runs, do not keep resetting it.
Turn off boiler: Isolate the boiler at the fused spur.
Check for leaks: Look for signs of water around the boiler. If present, turn off water and call an engineer immediately.
Engineer tasks: The engineer will insulation-test the pump, fan, and wiring, inspect the PCB for tracking, and repair or replace faulty components.
