Product Information
Full details
This guide is for owners of Glowworm boilers needing to replace a specific printed circuit board (PCB). The key benefit is restoring your boiler's central control system, ensuring proper operation and safety. A key caveat is that this part *must* be fitted by a certified Gas Safe engineer. The Glowworm S900847 PCB acts as the boiler's command centre, regulating all functions via switches, thermostats, and sensors, and implementing safety protocols to prevent issues like overheating or low water levels.

FAQs
Who should install the Glowworm S900847 PCB?
This part must be installed by a certified Gas Safe registered engineer due to the nature of boiler components and safety regulations.
What boiler models is this PCB compatible with?
This PCB (S900847) is designed for Glowworm boiler models such as Ultimate, Micron, Protherm, Ikon, and Xeon.
Can I return this part if I ordered the wrong one?
No, please note that this boiler part is non-returnable. Ensure you have correctly identified the required part number before purchasing.
What is the function of a printed circuit board in a boiler?
The PCB acts as the boiler's command centre, monitoring and regulating all operations using switches, thermostats, and sensors, while also enforcing safety precautions.
How do I know if my boiler's PCB needs replacing?
Symptoms can include erratic behavior, failure to ignite, repeated shutdowns, or specific error codes. A qualified engineer is needed to diagnose the problem accurately.
Is next-day delivery available for this part?
Orders received before 4 pm are usually dispatched for next business day delivery.
Troubleshooting
Boiler not responding or showing error codes
This could indicate a faulty PCB. A Gas Safe engineer should diagnose the issue and replace the PCB if necessary.
Intermittent heating or hot water issues
An aging or failing PCB may cause unpredictable operation. Professional diagnosis is required to confirm if the PCB is the root cause.
Boiler repeatedly shutting down
If safety sensors connected to the PCB are detecting abnormal readings (e.g., over-pressure, low water), the PCB will shut down the boiler. An engineer must investigate the underlying cause and potentially replace the PCB.
Pros and Cons
Pros
- Restores full boiler functionality by replacing the central control unit.
- Ensures critical safety features are operational.
- Directly compatible with specific Glowworm boiler models.
- Helps prevent further system damage by addressing a core component failure.
Cons
- Requires installation by a certified Gas Safe engineer, adding to cost and complexity.
- Non-returnable once purchased, emphasizing the need for accurate diagnosis before ordering.
- This is a spare part, not a complete system upgrade.
Setup, Compatibility & Care
Setup:
- Professional Installation Required: This part *must* be fitted by a Gas Safe registered engineer. Attempting self-installation can be dangerous and will void any warranties.
- Power Off: Ensure the boiler's electrical power supply is switched off at the main breaker before any work begins.
- Component Replacement: The engineer will carefully remove the old PCB and install the new Glowworm S900847.
Compatibility:
- This PCB is specifically designed for Glowworm boiler models including Ultimate, Micron, Protherm, Ikon, and Xeon.
- Verify your existing boiler model and the part number to ensure correct compatibility.
Care:
- The PCB itself requires no user maintenance. Proper care involves ensuring the boiler system is well-maintained overall.
- Regular servicing by a qualified engineer helps prevent issues that could overload or damage the PCB.
