What does the Glow-worm Flexicom F87 fault code mean?
The F87 fault code on a Glow-worm Flexicom boiler indicates a compliance issue, often related to the boiler’s ability to operate within the required safety and efficiency standards. This fault typically arises from a failure in the boiler’s internal components or sensors that monitor its performance.
Common Causes
- Faulty Sensor: A malfunctioning sensor may fail to provide accurate readings, leading to compliance errors.
- Internal Component Failure: Issues with internal components, such as the PCB (Printed Circuit Board), can disrupt the boiler’s operation and trigger the F87 fault.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that require professional handling for safety reasons.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F87 fault could range from £150 to £300, depending on whether a sensor replacement or PCB repair is necessary. This estimate reflects the cost of parts and labour for a qualified engineer.
