What does the Ideal Logic Max F75 fault code mean?
The F75 fault code indicates a calibration issue with the domestic hot water (DHW) temperature sensor in the Ideal Logic Max boiler. This can lead to inaccurate temperature readings and may affect the boiler’s ability to heat water effectively.
Common Causes
- Faulty DHW 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 communication and cause calibration faults.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to address this issue, as it involves gas and electrical components that require professional expertise. Attempting to fix it yourself could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for replacing the DHW temperature sensor is around £120 to £180, including parts and labour. This is based on the typical cost of the sensor and the time required for a qualified engineer to complete the repair.
