Sime Format 100c 6yrs old?

My boiler stopped working this morning, Homecall+ what a disaster!, gone bust and forgot to tell me! still helping themselves to my monthly premium though..in contact with FSCS. Getting a constant orange light, no DHW, no heating, nothing running in the boiler, wont ignite, when I run the DHW i hear a single click. Checked water pump seems to be free turning, boiler up till now running has been fine except the pump has been noisy off & on. Boiler seems dead! would appreciate any help..
