How to fix Ideal Mini fault code F95

What does the Ideal Mini F95 fault code mean?

The F95 fault code on the Ideal Mini indicates a problem with the domestic hot water (DHW) system temperature, suggesting that the boiler is unable to maintain the required temperature for hot water delivery. This can lead to insufficient hot water supply or overheating issues.

Common Causes

  • Faulty DHW Sensor: The temperature sensor may be malfunctioning, causing incorrect readings and triggering the fault code.
  • Blocked Heat Exchanger: A blockage in the heat exchanger can prevent proper heat transfer, leading to temperature discrepancies.

Can I fix it myself? (DIY)

It is advisable to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that require professional handling. Attempting to fix it yourself could pose safety risks.

Estimated Repair Cost (2026 UK Prices)

The estimated repair cost for resolving the F95 fault could be around £150 to £250, primarily depending on whether the DHW sensor needs replacement or if the heat exchanger requires cleaning or repair.
