What are the common Glow-worm boiler error codes?

Glow-worm boilers are equipped with advanced diagnostics that can help identify issues with the system. Here are some of the most common error codes that may be displayed on a Glow-worm boiler and what they mean:

• F1 – Indicates a fault with the ignition or gas supply
• F2 – Indicates a fault with the flame
• F3 – Indicates a problem with the fan or air pressure switch
• F4 – Indicates a fault with the heat exchanger
• F5 – Indicates a problem with the flow or return temperature sensor
• F6 – Indicates a fault with the flow or return thermistor
• F7 – Indicates a problem with the water pressure sensor or pump
• F9 – Indicates a fault with the diverter valve
• F11 – Indicates a problem with the gas valve or control board
• F12 – Indicates a fault with the PCB or wiring.

These are some of the most common error codes for Glow-worm boilers, but there may be other error codes that are specific to certain models or situations. If you are experiencing an error code on your Glow-worm boiler, please do get in touch and we can help.

What are the Glow-worm boiler blocking error codes?

Glow-worm boilers may display blocking error codes when a fault has been detected and the boiler is temporarily locked out to prevent further damage. Here are some of the blocking error codes that may be displayed on a Glow-worm boiler and what they mean:

• F1 – Indicates a fault with the ignition or gas supply
• F2 – Indicates a fault with the flame
• F4 – Indicates a fault with the heat exchanger
• F9 – Indicates a fault with the diverter valve
• F11 – Indicates a problem with the gas valve or control board
• F12 – Indicates a fault with the PCB or wiring

When a blocking error code is displayed, the boiler will not restart until the fault has been resolved. In some cases, the fault may be resolved by resetting the boiler, but in other cases, a qualified heating engineer may be required to diagnose and repair the issue. It’s important to address blocking error codes as soon as possible to prevent further damage to the boiler and ensure that it operates safely and efficiently.

What are the Glow-worm boiler locking error codes?

Glow-worm boilers may display locking error codes when a fault has been detected that requires immediate attention to prevent further damage or ensure safe operation. Here are some of the locking error codes that may be displayed on a Glow-worm boiler and what they mean:

• F13 – Indicates a fault with the boiler’s temperature sensors, which may be caused by a wiring issue, a faulty sensor, or a problem with the control board.
• F14 – Indicates a problem with the flow or return temperature sensors, which may be caused by a wiring issue, a faulty sensor, or a problem with the control board.
• F15 – Indicates a problem with the NTC thermistor or wiring, which may cause the boiler to overheat.
• F16 – Indicates a problem with the fan or wiring, which may cause the boiler to overheat.
• F22 – Indicates a problem with the low water pressure sensor or a water pressure drop, which may cause the boiler to shut down to prevent damage.
• F28 – Indicates a problem with the flue gas sensor or wiring, which may cause the boiler to shut down for safety reasons.

When a locking error code is displayed, the boiler will shut down and may not restart until the fault has been resolved. It’s important to address locking error codes immediately to prevent further damage to the boiler and ensure safe operation.
