It was damaged on the oven's main Board. The electricity is 54A and they create it with one phase cable so you must have this amount of electricity in your store. When it will work i will come back to write more. Now waiting 1 more month until the mainboard arrives and their New Years Eve holidays to finish. The worst experience on buying machine i had ever have.
And there is no Superior or Supervisor to talk for complains. Also the technician know few things about this machine. They ask other technicians from i don't know which factory. But you will not start your machine at the same day. They need more that a week to answer on basic questions.
