What it is

The Worcester Bosch 6.3mm male double connector is a wiring component used inside Worcester Bosch gas appliances. It provides a 6.3mm male spade connection point for two conductors, forming part of the internal wiring harness that carries low-voltage signals and supply between the boiler's control board, sensors and other electrical components. It is a serviceable spare intended for like-for-like replacement during repair or rewiring work on the Greenstar i ErP system boiler range and other compatible Worcester Bosch models.

Signs this part needs replacing

  • Intermittent operation or a boiler that cuts out when the wiring harness is disturbed
  • A loose, slack or poorly gripping spade terminal that will not stay seated on its tab
  • Discolouration, scorching or brittle insulation around the connector body
  • Corrosion or verdigris on the terminal, causing a poor electrical contact
  • Fault codes or ignition faults traced to a broken or intermittent connection in the harness

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the correct part for your model.
  • Confirm the existing connector matches the 6.3mm male double configuration before ordering.
  • The alternative number 1030999 may be quoted on older documentation for the same component.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
