What does the Ideal Mini F61 fault code mean?
The F61 fault code on the Ideal Mini indicates a problem with the domestic hot water (DHW) inlet temperature sensor. This fault suggests that the boiler is unable to accurately read the temperature of the incoming water, which can affect its ability to heat water effectively.
Common Causes
- Faulty DHW Inlet Temperature Sensor: The sensor may be malfunctioning or damaged, leading to incorrect temperature readings.
- Wiring Issues: Damaged or loose wiring connections to the temperature sensor can disrupt the signal 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 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 replacing the DHW inlet temperature sensor is around £150. This includes the cost of the part and labour, reflecting the typical pricing for a qualified engineer’s service in the UK.
