What it is
This is the Worcester Bosch 3-way service wiring harness, manufacturer part number 87161131570. It is the service loom used on the Greenstar Heatslave External range of oil-fired boilers, carrying the wiring connections required for the three-way service configuration. It is supplied as a service component for maintenance and repair work on the listed appliances.
Signs this part needs replacing
- Connector plugs or terminals show corrosion, heat discolouration or burning
- Insulation is cracked, chafed or exposed along the loom
- Individual cores are broken or intermittent, causing faults that change when the harness is moved
- Fault codes or service indications traced to the wiring rather than the component it serves
- Connector latches are broken, so plugs will not seat or lock securely
Before you order
- Confirm the boiler model against the fit list above, as the harness is listed for the Greenstar Heatslave External only
- Check the existing harness part number on the appliance or in the installation documentation
- Inspect the mating connectors and any related components for damage before fitting a replacement harness
- Isolate the appliance electrically before work begins and follow the manufacturer's wiring diagram on refitting
