Ariston Piezo Spark Generator Replacement Kit 65152148

The Ariston 65152148 is a piezo spark generator replacement kit, the component that produces the high-voltage spark at the ignition electrode when the appliance calls for heat or hot water. It sits within the ignition circuit of the Ariston Next range and is supplied as a kit rather than a bare generator. As a gas appliance part, it plays a direct role in proving and establishing flame at start-up.

• No audible clicking from the ignition circuit when the boiler receives a demand for heat or hot water
• The boiler goes to ignition lockout and requires repeated resets to fire
• Spark is weak, intermittent or absent at the ignition electrode despite a clean, correctly gapped electrode
• Appliance fires on some attempts but not others, with no other fault code pointing to gas or flame detection
• Ignition failure that persists after the electrode and its lead have been checked

• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Confirm your appliance model and serial details against the compatibility list, as the generator is listed for the Next 14 SFT NG UK only.
• If your documentation or existing component carries the earlier number 65158249, that number refers to the same item.
• Check the ignition electrode and lead condition at the same time, since a worn electrode can mimic a failed generator.
