What it is
The Ariston 65103331 is a spark generator used in Ariston ACO gas boilers. It produces the high-voltage spark that lights the burner at the ignition electrode during a demand for heat or hot water. It is classified as an ignition unit within the boiler's gas spares range.
Signs this part needs replacing
- The boiler fails to ignite, with no spark at the ignition electrode
- A clicking sound is heard but the burner does not light
- Ignition is intermittent, with the boiler locking out on some start attempts
- Visible damage, cracking or burning to the spark generator body or its leads
- Repeated ignition lockouts that persist after the electrode and leads have been checked
Before you order
- Confirm your boiler model against the fitment list above
- Check the GC number on your appliance data badge matches the model variant
- Verify the existing spark generator is marked with part number 65103331
- Inspect the ignition electrode and HT leads for damage before replacing the generator alone
