How to fix Ideal Logic Plus fault code F75

What does the Ideal Logic Plus F75 fault code mean?

The F75 fault code on the Ideal Logic Plus indicates a problem with energy consumption, typically related to the boiler’s ability to detect and manage its energy usage effectively. This can lead to inefficient operation and potential overheating issues if not addressed.

Common Causes

  • Blocked Flue: A blockage in the flue system can prevent proper ventilation, causing the boiler to misread energy consumption.
  • Faulty Sensors: Malfunctioning temperature or pressure sensors can lead to incorrect readings and trigger the F75 fault code.

Can I fix it myself? (DIY)

It is recommended to call a Gas Safe Engineer for any issues related to gas or electrical components. Attempting to fix these problems without proper training can be dangerous.

Estimated Repair Cost (2026 UK Prices)

The estimated repair cost for resolving the F75 fault could range around £150 to £300, depending on whether a sensor replacement or flue cleaning is required. This estimate reflects the cost of parts and labour for a qualified engineer.
