[Solved] Candy CS4 127TXME Smart Inverter Slim - Code 5by or Sby, what does it mean?

Dear forum users.

I am after buying a washing machine - Candy CS4 127TXME / 1-S.

The first wash is very good, the second one on the trouser program, I don't know because I haven't watched it. Washing as if finished but code 5by or Sby appeared on the display.

I have the impression that it did not spin very well (I always spin at 600 rpm, in earlier washing machines too) but maybe this program has such a charm ...
what does it mean? Because I can't find it anywhere.
Thanks for any info
I am uploading a photo of the display.

I bet it's Standby. They could have written End...

It crossed my mind but I rejected it as not very legible and that the manufacturer would not come up with such a stupid idea
I need to watch these messages carefully...

As suggested, the inscription is Stand By. Everything is OK
