What it is

The Worcester Bosch 87161202290 is an ignition harness assembly: the wiring loom that links the appliance control board to the ignition electrode on the 24 CDI family of Worcester Bosch boilers. It carries the ignition circuit as a complete assembly, with the leads and connectors already terminated, so the ignition path can be restored as a single unit rather than rebuilt wire by wire. It is a Worcester Bosch factory part, listed under GC number 299-515.

Signs this part needs replacing

  • The boiler fails to light, with no spark at the ignition electrode
  • Ignition is intermittent, or the appliance locks out shortly after a call for heat
  • The harness shows visible damage: cracked insulation, chafed or broken conductors, or heat-affected wiring near the electrode
  • Connectors are loose, corroded or pushed back out of their housings
  • Ignition faults that persist after the electrode and its gap have been checked and set

Before you order

  • Confirm the appliance GC number and model against the compatibility list; the 24 CDI range uses several variants and the harness must match the appliance
  • Check the previous part number SSAHAR335 if you are replacing an older stock item
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
