Worcester Bosch Ignition & Flame Sensing Electrode Set - 87181070870 / 87161163810

The Worcester Bosch Ignition & Flame Sensing Electrode Set is a replacement boiler electrode kit designed for a wide range of compatible Worcester Bosch Greenstar boilers.

Originally supplied under Worcester part number 87181070870, this electrode set has now been superseded by current Worcester Bosch part number 87161163810.

The kit is used within the combustion system to provide reliable burner ignition and flame monitoring. The ignition electrode generates the spark required to ignite the burner, while the flame-sensing electrode monitors the presence of the flame to help ensure safe boiler operation.

How the Electrode Set Works

The electrode assembly performs two critical functions within the boiler's combustion system.

The ignition electrode produces the high-voltage spark required to ignite the gas and air mixture at the burner.

The flame sensing electrode then monitors whether a stable flame has been successfully established. If the boiler does not detect a flame, the control system can stop the gas supply and attempt the appropriate ignition sequence.

This makes the electrode assembly an important safety and operational component within the boiler.

Common Symptoms of Worn Electrodes

Worn, damaged or contaminated electrodes may contribute to symptoms such as:

  • Boiler failing to ignite
  • Intermittent ignition
  • Repeated ignition attempts
  • Ignition lockout faults
  • Boiler lighting and then shutting down
  • Poor or inconsistent flame sensing
  • Visible cracking or deterioration of electrode insulation

These symptoms can also be caused by other ignition, gas or combustion components, so professional diagnosis should always be carried out before replacing parts.

Part Number Supersession

Worcester Bosch part number 87181070870 has been superseded by 87161163810.

If your appliance parts diagram, existing component or service documentation references 87181070870, the current 87161163810 electrode kit is the recognised replacement.

Typical Kit Contents

Depending on current Worcester Bosch packaging, the kit may include:

  • Ignition electrode component(s)
  • Flame sensing electrode
  • Burner sealing gasket
  • Additional metallic seal / clip

Always check the supplied package contents before installation as Worcester Bosch may revise service-kit packaging.

Important Compatibility Information

Do not order solely by boiler range or appearance.

Worcester Bosch has produced multiple boiler revisions using different electrode assemblies. Always confirm compatibility against the boiler model, Gas Council number, FD number, serial number and existing part reference.

If the existing boiler documentation references 87181070870, the replacement part is generally 87161163810, but appliance compatibility should still be checked before installation.

Professional Installation Required

Ignition and flame-sensing electrodes are located within the combustion area of the boiler.

Replacement requires removal of combustion components and correct inspection of seals, burner condition, electrode position and combustion performance. Installation must therefore be carried out by a suitably qualified Gas Safe registered engineer.

Following replacement, the appliance should be correctly reassembled, tested for gas tightness where required and combustion checked in accordance with Worcester Bosch servicing instructions.
