Stock · 5 units

SIT ignition transformer, model 504 NAC, for Ariston boilers in the Genus, Codex, Excalibur, Intesa, Microgenus, and Selecta ranges, among others. It generates the high-voltage spark that ignites the burner when the boiler starts. Operates at 230V. It is replaced when the boiler does not ignite, you hear the ignition attempt without a flame, or it goes into lockout due to ignition failure.

Guide

How to check if ref. 65100514 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 65100514. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms and faults that the ignition transformer 65100514 resolves.

The ignition transformer generates the high voltage for the spark of the electrodes. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler does not ignite on any attempt.

    Cause: The transformer does not produce the spark necessary to ignite the burner.

    Check the electrode during the startup in installer mode to see if there is a spark before replacing the part.

  • 02

    After the ignition attempt, the boiler locks out and requests a reset.

    Cause: It is the safety cut-off of the control board when it does not detect a flame within the expected time.

    Check the fault code on the display, identify a lock due to ignition or a lock for another reason.

  • 03

    The ignition works worse when the boiler has been running for a while.

    Cause: The transformer loses efficiency with accumulated heat and the output current decreases when hot.

    Compare the behavior in cold conditions and after prolonged use to see if the fault depends on the temperature.

  • 04

    The spark appears weak or intermittent at the electrode.

    Cause: The winding degrades with use and the arc loses strength even though the transformer continues to operate.

    Check the cleanliness and alignment of the electrode; a dirty or poorly adjusted electrode produces the same symptom as a faulty transformer.

Fault codes for Ariston that this part resolves.

CodeFaultDiagnosis and solution
A01No flame after the safety time (lockout due to ignition fault).The spark transformer/generator 65100514 does not deliver high voltage to the electrodes, there is no spark, and the burner does not ignite, causing the boiler to lock in A01. Visually check for a spark during startup, and if there is none, check the wiring/ground and replace or test the generator (also ruling out electrodes and PCB).

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
