What it is

The Ariston 64202273 is an ionisation electrode for Ariston Genus Premium EVO HP condensing boilers. It sits in the combustion circuit and provides the flame-sensing signal the control board uses to confirm a burner flame is present. It is a service part for the 45kW and 65kW HP models.

Signs this part needs replacing

  • Boiler locks out or fails to prove flame shortly after ignition
  • Repeated ignition attempts followed by lockout, with no fault traced to the gas valve
  • Flame signal becomes weak or erratic during operation
  • Electrode tip shows heavy contamination, cracking or erosion
  • Intermittent lockouts that clear after a reset

Before you order

  • Confirm the boiler model and kW rating against the fitment list
  • Check the part number on the existing electrode where it is visible
  • Inspect the electrode lead and connector for damage before replacing
  • Isolate the appliance and follow the manufacturer's service instructions
