What it is
The Glow-worm S1054700 is a spark ignition component used in Glow-worm domestic boiler assemblies. It produces the ignition spark that lights the gas at the burner when the appliance receives a call for heat or hot water. The part sits within the Glow-worm range of domestic boiler spares and is supplied as an individual component.
Signs this part needs replacing
- The boiler runs through its ignition sequence but does not light, then locks out
- No spark is visible or audible at the electrode when the appliance is calling for heat
- Repeated ignition attempts are followed by a fault code or lockout on the display
- Cracking, soot build-up or corrosion is visible on the electrode tip or its ceramic insulator
- Ignition is intermittent and the boiler sometimes fires only after being reset
Before you order
- Check the boiler's GC number and serial plate to confirm the correct spare for the model
- Match the part number S1054700 against the number on the component being replaced
- Inspect the surrounding ignition leads and seals, as these are often disturbed during replacement
