Can I attempt to fix a Worcester Boiler Error Code 522 myself, or should I call a professional?

While you can try some basic troubleshooting steps, like resetting the boiler and checking the water pressure, it's generally best to call a qualified heating engineer to diagnose and repair a Worcester Boiler Error Code 522. Low water pressure issues can be complex, and attempting to fix them yourself without the proper knowledge and tools could lead to further damage or safety hazards. A professional can accurately identify the root cause and provide a safe and effective solution.
