What does the Glow-worm Energy F95 fault code mean?
The F95 fault code on the Glow-worm Energy boiler indicates a domestic hot water (DHW) electrical fault. This typically suggests an issue with the electrical components responsible for heating the water, which may affect the boiler’s ability to provide hot water.
Common Causes
- Wiring Issues: Damaged or loose wiring connections can disrupt the electrical flow, leading to the F95 fault code.
- Faulty DHW Sensor: A malfunctioning domestic hot water sensor may fail to communicate the correct temperature readings, triggering the fault.
Can I fix it myself? (DIY)
It is strongly advised to call a Gas Safe Engineer for this issue, as it involves electrical components that can be dangerous if handled improperly. Attempting DIY repairs could void your warranty or lead to further complications.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F95 fault could range from £150 to £300, depending on whether wiring repairs or component replacements (like a DHW sensor) are needed. This estimate includes parts and labour, reflecting the complexity of electrical issues in boilers.
