Ariston Piezo Spark Generator Combi A 24/30 61002105-20

The Ariston piezo spark generator 61002105-20 is the ignition component that generates the high-voltage spark at the burner electrode on Ariston combination gas boilers. It sits within the ignition circuit and is operated when the boiler receives a call for heat or hot water, providing the spark that lights the gas at the burner. This part is manufactured by Ariston and is listed for the Combi A 24/30 family, with a wider fit across a number of Ariston gas boiler ranges.

• The boiler attempts to fire but there is no spark at the burner electrode.
• A clicking or ticking sound is heard from the ignition circuit without the burner lighting.
• The boiler repeatedly goes to ignition lockout on a call for heat or hot water.
• The appliance fails to light intermittently, particularly in damp conditions or after long periods out of use.
• No visible spark is observed at the electrode when the ignition sequence is triggered during a service visit.

• Check the appliance GC number and model plate against the compatibility list, as the same boiler range can use more than one ignition arrangement.
• Confirm the number on the existing component against 61002105-20 and the alternative numbers listed below before ordering.
• Inspect the ignition lead and electrode at the same time; a damaged lead or worn electrode can produce the same fault symptoms.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
