How to fix Ideal Mini fault code F26

What does the Ideal Mini F26 fault code mean?

The F26 fault code on the Ideal Mini indicates a fan fault, which typically means that the fan is either not operating correctly or is not detected by the boiler’s control system. This can lead to inadequate ventilation and potential overheating, affecting the boiler’s performance.

Common Causes

  • Faulty Fan: The fan may have failed due to wear and tear or electrical issues, preventing it from spinning or operating properly.
  • Wiring Issues: Damaged or loose wiring connections to the fan can disrupt its operation, leading to the F26 fault code being triggered.

Can I fix it myself? (DIY)

It is recommended to call a Gas Safe Engineer for any repairs related to the fan, as these involve gas and electrical components that can be dangerous if handled improperly. Attempting to fix these issues without proper training can pose serious risks.
