What does the Ideal Logic Max F93 fault code mean?
The F93 fault code on the Ideal Logic Max indicates a calibration error with the domestic hot water (DHW) flow switch. This error typically suggests that the flow switch is not detecting water flow correctly, which can affect the boiler’s ability to provide hot water.
Common Causes
- Faulty Flow Switch: The flow switch may be defective or damaged, preventing it from accurately measuring water flow.
- Blocked Pipes: Obstructions in the water pipes can restrict flow, leading to incorrect readings by the flow switch.
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 the F93 fault code is around £150 to £250, primarily for the replacement of the flow switch and associated labour. This cost reflects the complexity of the repair and the need for a qualified technician.
