What does the Glow-worm Betacom F67 fault code mean?
The F67 fault code indicates a problem with the domestic hot water (DHW) return temperature sensor in the Glow-worm Betacom boiler. This sensor is crucial for monitoring the temperature of the water returning to the boiler, and a fault may lead to inefficient heating or no hot water supply.
Common Causes
- Faulty Temperature Sensor: The sensor may be malfunctioning or damaged, leading to incorrect temperature readings.
- Wiring Issues: Damaged or loose wiring connections to the sensor can disrupt its functionality and cause the fault code to appear.

It is recommended to call a Gas Safe Engineer for this issue, as it involves electrical components and gas safety regulations. Attempting to fix it yourself could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for replacing the DHW return temperature sensor is around £120. This includes the cost of the part and labour, as sensor replacements typically require professional installation to ensure safety and compliance.
