What it is
The Worcester Bosch 87186908270 is a high-voltage (HV) and ignition wiring harness assembly used on Worcester Bosch Greenstar gas boilers. It carries the high-voltage supply and the ignition circuit between the boiler's control electronics and the ignition electrode, allowing the electrode to spark and the burner to light. The harness is supplied as a complete assembly with its connectors already fitted.
Signs this part needs replacing
- The boiler fails to light, with no spark at the ignition electrode.
- Ignition lockout or flame-failure faults that return after resetting the appliance.
- Cracked, brittle or heat-damaged insulation along the harness leads.
- Loose, corroded or discoloured terminals at the electrode or the control board.
- Visible arcing marks or a burnt smell around the ignition lead.
Before you order
- Check the boiler's GC number and model against the compatibility list; more than one harness variant is used across the Greenstar range.
- Quote the alternative number 2247093 when cross-referencing older documentation or parts listings.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
