What does the Baxi Platinum F68 fault code mean?
The F68 fault code indicates that the domestic hot water (DHW) pressure is too low, which can prevent the boiler from functioning correctly. This issue can lead to inadequate hot water supply and may require immediate attention to restore normal operation.
Common Causes
- Low Water Pressure: The pressure in the system may have dropped below the minimum required level due to leaks or insufficient filling.
- Faulty Pressure Relief Valve: A malfunctioning pressure relief valve can cause water to escape, leading to low pressure in the system.
Can I fix it myself? (DIY)
You can attempt to fix low pressure by checking the pressure gauge on the boiler and using the filling loop to add water to the system if necessary. However, if you suspect any gas or electrical issues, it is crucial to call a Gas Safe Engineer for safety reasons.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F68 fault could be around £150 to £250, depending on whether the issue is simply a refill or if a component like the pressure relief valve needs replacement.
