What is a F2 boiler fault?

What's this mean? Woke up freezing cold and the boiler screen is showing F2. Can I fix this myself?

"Hi Karen. F2 on an ideal boiler is flame loss. It will need to be looked at by a gas safe engineer. Regards Kevin"

"If it’s an ideal boiler then it’s a problem with combustion. Make sure your gas supply is okay and if it’s not that you’ll need to call a heating engineer"
