Ferroli F 30 B Fault codes & diagnostics

What to check first

1. Locate the filling loop (a flexible metal hose) underneath the boiler.
2. Open the small valve or tap on the filling loop to allow water to enter the system.
3. Watch the pressure gauge on the front of the boiler until the needle reaches the green zone (usually 1.0 to 1.5 bar).
4. Close the valve tightly and check that the fault light has cleared.

Parts commonly replaced

What to check first

1. Locate the external filling loop, which is usually a metal braided hose underneath the boiler.
2. Open the small valve on the filling loop to allow water to enter the system until the pressure gauge reads between 1.0 and 1.5 bar.
3. Close the valve firmly and ensure the boiler resets itself.

What to check first

1. Locate the two small taps (filling loop) connected to the pipes underneath your boiler.
2. Open the taps slowly to let fresh water enter the system until the needle on the pressure gauge reaches approximately 1.5 bar.
3. Close both taps tightly and check the boiler display to see if the error light has cleared.
