Glow-worm Printed Circuit Board Interconnect S202210

The printed circuit board interconnect is a Glow-worm wiring link used inside the appliance to carry signals between the main PCB and the surrounding electrical components. It is supplied under part number S202210 and was previously listed under code 202210. The part belongs to the EnergySaver range of Glow-worm boilers, where it forms part of the control and connection assembly rather than the gas-carrying side of the appliance.

• The boiler locks out or fails to complete its start sequence with no obvious fault elsewhere.
• Error codes appear on the display that point to a communication or control fault.
• The appliance runs intermittently, cutting in and out without a consistent pattern.
• Visible damage to the interconnect, such as scorching, brittle insulation or a loose or corroded plug.
• Faults that return after the main board has been replaced, suggesting the link between boards is at fault.

• Confirm the GC number on the appliance data badge against the compatibility list before ordering.
• Check that the existing part carries the code 202210 or S202210, as this interconnect is listed against both.
• Match the model name and variant exactly, including the P suffix where fitted, as the range covers several versions.
• Work on the appliance electrical connections should be carried out by a competent person, with the boiler isolated from the mains supply first.
