Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F.28Start-up fault: ignition failedIf the ignition transformer is faulty, no spark is generated at the electrodes and the burner does not ignite. Check for the presence of a spark during start-up and measure the power supply to the transformer and high voltage output/insulation along with wiring and grounding.
F.29Operating fault: failed ignition attemptsA faulty or intermittent ignition transformer causes spark failures during retries and the boiler locks out with F.29. Check for sustained spark in each attempt, continuity/output of the transformer, and the condition of ignition and ground cables.
How do I know if this ignition transformer is for my boiler?
Verify the reference A000035144 printed and ensure your model is on the list of compatibles; also compare the connections with the original part. It is a Saunier Duval part (original part from the Vaillant Group, shared with Glow-Worm).
What is it used for?
The ignition transformer generates the high voltage for the electrode spark.
Is there no spark or repeated ignition faults?
No spark at the electrode despite having gas.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Check the electrode and the high voltage cable.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
