What does the Ideal Mini F72 fault code mean?
The F72 fault code on the Ideal Mini boiler indicates a central heating system outlet fault, which typically suggests that there is an issue with the flow of water from the boiler to the heating system. This could be due to a blockage, pump failure, or other circulation problems.
Common Causes
- Blocked Pipework: Debris or sludge in the heating system can obstruct water flow, leading to the F72 error.
- Faulty Pump: If the circulation pump is malfunctioning or has failed, it may not be able to move water through the system effectively.
Can I fix it myself? (DIY)
If you are comfortable with basic plumbing, you can check the pressure gauge and ensure it is within the recommended range (typically 1-1.5 bar). If the pressure is low, you can top it up using the filling loop. However, for any gas or electrical issues, it is crucial to call a qualified Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F72 fault could range from £150 to £300, depending on whether the issue is a simple blockage or requires pump replacement. A new pump can cost around £200, plus labour charges.
