What Does Glowworm F13 Fault Code Mean
The Glow Worm F13 fault shows a communication problem inside the boiler. This issue usually involves the sensor, wiring, or PCB. The PCB controls all boiler functions and shuts the system down when it detects a fault. This action protects your boiler from further damage.
Is Glowworm F13 Fault Dangerous
The F13 fault is not directly dangerous, but you should not ignore it. Your boiler will stop working, and your home will lose heating and hot water. If you delay repairs, the problem can get worse and cost more to fix.
Common Causes of F13 Fault Code
Faulty Sensor
Sensors monitor temperature and pressure. A damaged sensor can send wrong signals to the PCB and trigger the fault.
Wiring Issues
Loose or damaged wiring can block communication between components. This issue often causes sudden shutdowns.
PCB Failure
The PCB acts as the brain of the boiler. If it fails, the boiler cannot process data correctly. This fault is one of the most expensive to repair.
Loose Connections
Poor electrical connections can interrupt signals. Even a small loose wire can trigger the F13 code.
Can You Fix F13 Fault Yourself
You should not try to fix this fault yourself. Boilers use gas systems and require expert handling. Only a Gas Safe engineer should inspect and repair the issue.
You can try a simple reset:
- Turn the boiler off and on
- Press the reset button
- Wait a few minutes
If the fault returns, stop and call an engineer.

Follow the given below steps to fix the glowworm f13 fault code
- Call a Gas Safe Engineer
A qualified engineer will inspect your boiler and find the exact issue.
- Run Diagnostics
The engineer will test sensors, wiring, and PCB connections.
- Replace Faulty Parts
The engineer will replace damaged components with approved parts.
- Test the Boiler
The system will be tested to confirm safe and proper operation.
Why Boiler Servicing Prevents Faults
Regular servicing keeps your boiler running efficiently. An engineer will clean parts, check performance, and spot issues early. This process reduces the risk of sudden breakdowns like the F13 fault.
When to Replace Your Boiler
If your boiler is old and repairs cost too much, replacement may be the best option. New boilers use less energy and offer better performance. They also come with longer warranties.

Frequently Asked Questions
Usually on a normal PC keyboard (that also does not have F13) you can hit Shift F1 to access F13. There are no unique scan code for keys F13-F24, their scan codes are literally Shift+F1… F12. If you’re using something trust has a binding for F13, try hitting Shift+F1.
No, you should not fix this fault yourself. Boilers require professional handling. A Gas Safe engineer must inspect and repair the issue.
You should book annual boiler servicing. Regular checks help detect issues early and keep your boiler running efficiently.
F10 fault code indicates a problem with the central return flow thermistor in Glow Worm boilers. The fault commonly occurs due to a faulty temperature sensor or short circuit in the boiler system. Reset attempts may temporarily resolve the issue, but professional inspection is recommended for safety.
