Review on De "Longhi Magnifica S ECAM 21.117 coffee machine, silver / black by Anastazja Adziarejka ᠌

Bought this coffee machine. I read the instructions, turned it on, brewed coffee, made foam. Everything is fine. The second time you turned on the machine issued a general accident sign, this is an exclamation point in a red triangle. This despite the fact that all parts were washed and everything was done according to the instructions. Subsequent inclusions were successful through time. The problem was solved by turning off and on the main switch. P. S After calling the master from the official service, it turned out that the manufacturer installed an unusable outdated power board, which I was successfully replaced.
