What does the Ideal Mini F73 fault code mean?
The F73 fault code on the Ideal Mini indicates a problem with the domestic hot water (DHW) system inlet, which may prevent the boiler from supplying hot water effectively. This issue can arise from various factors affecting the water supply or internal components.
Common Causes
- Blocked Inlet Filter: A blockage in the inlet filter can restrict water flow, leading to the F73 error.
- Faulty Flow Sensor: If the flow sensor is malfunctioning, it may not detect water flow correctly, triggering the fault code.
Can I fix it myself? (DIY)
It is advisable to call a Gas Safe Engineer for this issue, as it involves the boiler’s water supply system and may require professional tools and expertise to diagnose and repair safely.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F73 fault could be around £150 to £250, primarily depending on whether the inlet filter needs cleaning or replacement, or if the flow sensor requires servicing or replacement.
