Good but not reported frequent descaling

Received as a gift in February, she worked 3 months prior to stop pumping of water from sarrêter full distribution and end with a red error code with wrench and the number 5. After a call to customer service, it makes me do some manipulation (off, on again, remove the tank) and of course we wonder if the scaling was done. What I say yes because the scaling symbol mavait indicated a few weeks ago this need.
So deposit machine at my authorized repairer, who 10 days na me said he found no fault.
Actually it worked one month.

Then rebelote early July. I decided to lemmener directly from my servicer. (This time I even made a video of failure)
15 days later my repairman tell me that he just had to make Lentretien (= descaling). To which I replied that it wasnt indicated by the symbol but an error code. Obviously it charges me Lentretien.

So I recontacted Saeco / philipps for a commercial gesture. I'll spare you the e-mail exchanges that boils down to: you should have done descaling!

So outcome of the case, when we buy a machine to 400, must be scaled every 2 months, than before knowing whether it takes to make you lose one or two cups and 3 liters of water before to have the error code 5. ( FYI i also of water softener on my domestic circuit, so the scale does not exist)
I will recover my machine tonight to pay my 45 ny repairer who can do nothing and the bad pub for saeco and if I have to choose a machine in the future I would go on delonghi.

Hoping that it might help some to make their choice.
