What does the Ideal Logic Plus F64 fault code mean?
The F64 fault code on the Ideal Logic Plus indicates a problem with the pressure switch, which is responsible for monitoring the boiler’s water pressure. This fault can prevent the boiler from operating correctly, leading to heating and hot water issues.
Common Causes
- Blocked Pressure Switch Tube: A blockage in the tube connecting the pressure switch to the system can prevent accurate pressure readings.
- Faulty Pressure Switch: The pressure switch itself may be malfunctioning or damaged, leading to incorrect signals being sent to the boiler’s control board.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as working with gas appliances can be dangerous. Attempting to fix the pressure switch without proper training may lead to further complications.
