What does the Ideal Logic Plus F30 fault code mean?
The F30 fault code on the Ideal Logic Plus indicates a problem with the temperature sensor, which is responsible for monitoring the boiler’s water temperature. This fault can lead to inefficient heating or the boiler shutting down to prevent damage.
Common Causes
- Faulty 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 cause communication failures between the sensor and the boiler’s control board.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair the issue, as working with gas appliances can be dangerous. Attempting to fix electrical components without proper training can also pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for replacing a faulty temperature sensor on an Ideal Logic Plus is around £150 to £200. This includes the cost of the part and labour, as the sensor itself typically costs about £50 to £80, with the remainder covering the engineer’s time.
