Worcester Bosch Electrode Kit Greenstar I Junior 87161163810

The Worcester Bosch 87161163810 is an electrode kit for Greenstar and Greenstar ErP boilers. The ignition (spark) electrode creates the spark that begins combustion inside the burner, while the flame sensing electrode checks that a flame is actually present. That sensing function stops the boiler from continuing to supply gas when there is no flame. It is classified as a combustion and exhaust component.

• The boiler attempts to fire but does not light and goes to lockout
• No spark is visible at the burner during an ignition attempt
• Several ignition attempts are needed before the burner lights
• A flame detection fault or lockout occurs shortly after the burner has lit
• The electrode tip shows heavy carbon build-up, cracking, or an opened spark gap

• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Check the GC number and the appliance data plate to confirm the boiler model before ordering.
• Earlier number 87181070870 may be fitted to older appliances, so compare it against the electrode being removed.
• Check whether a gasket or seal is needed for the burner cover on the specific model being worked on.
