What does the Ideal Mini F67 fault code mean?
The F67 fault code on the Ideal Mini indicates a domestic hot water (DHW) system flow fault, which typically means there is insufficient water flow to meet the demand for hot water. This can lead to the boiler shutting down to prevent damage or inefficiency.
Common Causes
- Blocked Filter: A blockage in the DHW filter can restrict water flow, causing the fault code to appear.
- Faulty Flow Sensor: If the flow sensor is malfunctioning, it may not accurately detect the water flow, triggering the F67 error.
Can I fix it myself? (DIY)
It is advisable to call a Gas Safe Engineer for this issue, as it may involve gas or 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 resolving an F67 fault could range from £150 to £300, depending on whether the issue is a simple filter clean or requires replacement of the flow sensor, which can be more expensive.
