how can i fix my modena ferroli 80E boiler?

twelve weeks ago, my central heating and hot water stopped wrking, i had to move out and stay with friends as i have a young child and the house is too cold to live in. My plumber said it was the coil although did not actually open the boiler to see, and apparent;ly the coils you can not get hold of so told me i need a new boiler, this is not an option as i just dont have the cash. All the indicator lights are wrking except the pilot ones, its just like theres nothing powering up when you turn the water or heating on, normally makes a blowing sound but doesnt anymore....i hope you can help
