Worcester Bosch Wiring Harness HV 8716117692

The Worcester Bosch HV wiring harness, part number 8716117692, is a factory wiring loom used in the Greenstar ErP Compact range of gas boilers. It carries the high-voltage connections between the boiler's control electronics and the components they switch, so the control board can power and regulate the appliance correctly. As a Worcester Bosch spare, it is the same loom specified for the Compact combi and system models listed below.

• The boiler cuts out intermittently or loses power to a component without an obvious mechanical fault.
• Fault codes relating to the control board, fan, pump or ignition circuit appear and clear at random.
• Visible damage to the loom: chafed or cracked insulation, scorched or discoloured wiring, or a burnt smell near the harness.
• Loose, corroded or heat-damaged spade and plug connectors that will not seat firmly.
• Continuity testing shows an open circuit or a short on one or more conductors in the loom.

• Check the GC number and model on the boiler data badge against the compatibility list before ordering.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Compare the connector layout and wire count on the existing harness with the replacement before fitting.
• The alternative number 1030975 may appear on older documentation or labels for the same harness.
