difficult beginnings

nickel first day! we could test more coffee, chocolate etc .. and the next day .... impossible to operate the machine. 3sinaux red light flashing at the same time.
Fortunately on Saturday the service is open and after having fought with their advisor ("you can still send it back to Amazon, you have a period of 7 days" - "Bah !! we have not used the machine !!! It n 'is new! ") it ended up making us manipulation with T-Disc test.
Obviously we have to think about removing the T-Disc between uses, do not let the vacuum in the machine. For more worries!
