What it is

The Baxi 7830457 is a low voltage wiring harness used in Baxi System 2 boilers. It forms part of the boiler's low voltage electrical circuit, carrying control and sensor signals between components within the appliance. It is listed by the manufacturer under the Baxi 600, 800 and Assure System 2 appliance families.

Signs this part needs replacing

  • Fault codes or lockouts traced to a break in the low voltage circuit
  • Intermittent operation or random shutdowns linked to a loose or damaged loom
  • Visible damage to the harness, such as chafed, scorched or brittle insulation
  • Connectors that are corroded, loose or no longer clipping securely
  • Continuity testing showing an open circuit on one or more conductors

Before you order

  • Confirm the boiler model and that it is a System 2 appliance
  • Check the existing harness part number against 7830457 where it is still legible
  • Inspect the connectors and routing to confirm the fault lies with the harness rather than another component
  • Isolate the appliance from the electrical supply before any inspection or replacement work
