Glow-worm Electrode Kit GLOWWORM0020152564

The Glow-worm 0020152564 is an electrode kit for Glow-worm gas appliances. In a gas appliance, electrodes perform two critical roles. The ignition electrode creates the spark that starts combustion, while the flame sensing electrode verifies that a flame is present in the burner. The flame sensing electrode detects the presence of a flame by sensing the ionisation current; if no flame is detected, the appliance's control board shuts off the gas supply to prevent an unsafe release. This verification is essential for safe operation. This kit provides the necessary electrodes to maintain these functions and is a service part intended for replacement when the original electrodes are worn or faulty. Regular inspection of electrodes during annual servicing helps ensure reliable ignition and safe flame detection.

• The appliance fails to ignite or repeatedly locks out.
• No spark is visible at the ignition electrode during the ignition cycle.
• The appliance reports a flame detection fault or shows an error code related to flame sensing.
• The electrode tips show signs of damage, corrosion, or heavy carbon build-up.
• Heating or hot water operation is intermittent, often shutting down shortly after start-up.
• The appliance may attempt to ignite multiple times before locking out.

• Check your appliance's model and serial number to confirm compatibility.
• Compare the part number 0020152564 with the existing part.
