The Glow-worm 0020014404 is a wiring harness for Flexicom SX gas boilers. It carries the electrical connections between the boiler's control components, sensors and other internal parts. The harness is supplied as a complete assembly with its fitted plugs and connectors.

Signs this part needs replacing

  • Loose, corroded or discoloured connector pins at the harness plugs
  • Boiler failing to fire or components not receiving power

Before you order

  • Inspect the existing harness and connectors to confirm the fault lies with the wiring
