What it is

The Worcester Bosch 87377033590 ionisation electrode set is a flame-sensing component for Worcester Bosch boilers. It monitors the flame by sensing the ionisation current at the burner, giving the appliance control board confirmation that ignition has taken place and that combustion is continuing. The electrode is supplied as a set under part number 87377033590.

Before you order

  • Confirm the part number 87377033590 matches the component being removed.
  • Check that the existing electrode is an ionisation electrode rather than an ignition electrode.
  • Note the appliance model and any fault codes shown, so the diagnosis can be confirmed before ordering.
