Ferroli combi boiler F1 fault?

Any help appreciated. The gas meter is open and working fine. Boiler shows f1 fault code for no burner ignition tried holding reset button as suggested in online manual but it can't ignite and just flashes blue with F1 after about 30 seconds and 3 attempts to ignite. Any idea on how else to fix this or what could be wrong.
Do I contact my gas supplier or boiler manufacturer or even just my landlord?

No hot water or heating :(

Thanks!
