Worcester Bosch 87161427520 Ignition Electrode - Danesmoor/Heatslave

The Worcester Bosch ignition electrode kit, part number 87161427520, is a replacement ignition component for Worcester Bosch oil-fired appliances. It sits at the burner and provides the spark that lights the fuel at start-up, so the appliance can move from a standby state into a running cycle. The kit is listed under the Worcester Bosch electrodes and ignitions spare part group and is used across the Danesmoor and Greenstar Heatslave ranges.

• The burner fails to light, or lights only intermittently, despite the appliance calling for heat.
• Repeated lockouts on start-up that clear after a reset and then return.
• No visible spark at the electrode when the burner is observed during an ignition attempt.
• The electrode tip is cracked, eroded, sooted or heavily carboned, or the ceramic insulator is damaged.
• The electrode lead or its connection is loose, brittle or showing signs of heat damage.

• Confirm the appliance model and, where available, the GC number against the compatibility list before ordering.
• Check the existing electrode and its lead for damage so that any associated gasket, seal or lead can be ordered at the same time if needed.
• Note the alternative number 1018483 and the reference 11593701 when cross-referencing against the old part.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
