The F1 error code on the IDEAL SYSTEM 15 boiler indicates "Low Water Pressure."

To resolve it:
1. Check the system pressure gauge; if it's below 0.3 bar, the boiler will not operate.
2. Repressurize the system to the correct level (typically around 1.0–1.5 bar).
3. If the error persists, check for leaks or pressure drops in the system.

If the issue remains unresolved, further inspection by a qualified engineer may be needed.
