What it is

The Alpha 6.8420930 is a spark electrode used on Alpha gas boilers in the 240 and 280 families, including Ocean Style 80 variants. It provides the ignition spark at the burner, so the appliance can light on a demand for heat or hot water. The electrode is listed under gas boiler spares in the electrodes category.

Signs this part needs replacing

  • The boiler fails to ignite and goes to lockout on a call for heat or hot water
  • No spark is visible or audible at the burner during the ignition sequence
  • The electrode tip is heavily sooted, corroded or bridged with carbon
  • The ceramic insulator is cracked, chipped or tracking, allowing the spark to arc to earth
  • The electrode lead or its insulation is damaged, brittle or loose at the terminal

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Compare the electrode body, tip position and terminal against the part removed from the appliance
  • Inspect the ignition lead and its connections, as a poor lead can mimic electrode failure
  • Check the burner earth and electrode gap before condemning the electrode
