What it is

The Ariston 65100852 is an inter ignition blade used in the ignition circuit of Microsystem RFFI gas boilers. It forms part of the ignition unit, carrying the spark that lights the burner on demand. It is listed by Ariston under the ignition unit category for the Microsystem 21 RFFI and 28 RFFI ranges.

Signs this part needs replacing

  • The boiler fails to light and goes to lockout on a call for heat
  • No spark is heard at the burner during ignition attempts
  • Ignition is intermittent, with the boiler lighting only after several attempts
  • Visible damage to the blade, such as a cracked body, burnt tip or arcing marks
  • The ignition lead or electrode connection shows corrosion or poor contact at the blade

Before you order

  • Confirm the boiler model is a Microsystem 21 RFFI or 28 RFFI
  • Check whether the appliance is the LPG or NG variant
  • Confirm the edition of the appliance, as Edition 2 and Edition 3 are both listed
  • Match the part number 65100852 against the number on the existing component
