What does the Baxi Platinum F22 fault code mean?
The F22 fault code on a Baxi Platinum boiler indicates a dry fire condition or low water pressure within the system. This can prevent the boiler from operating safely and efficiently, leading to heating and hot water issues.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water supply, causing the boiler to shut down to prevent damage.
- Dry Fire Condition: This happens when the boiler attempts to operate without adequate water, often due to a malfunctioning pressure sensor or pump.
Can I fix it myself? (DIY)
You can check and refill the water pressure by locating the filling loop and ensuring the pressure gauge reads between 1-1.5 bar. If the issue persists or if you suspect a gas or electrical fault, it is crucial to call a qualified Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F22 fault could be around £150-£250, primarily for pressure testing and potential component replacement, such as a pressure sensor or pump, depending on the specific cause of the fault.
